At the moment I have got 2 class. The main class, and the LinearLayout class that returns linearLayout
The layout class has a button and a edittext view, and its going to bundle all up and return a view back to the main class to use it.
In the main class there will be a ArrayList that will be created here dynamically and in then end, will display them out.
Problem
I want to use QR scanner on each of button. I passed the context to the LinearLayout class in order to create components and create the scanner on the button click. Which it works on click of each created button in the layout list and it automatically callback to the main class onActivityResult method.
But then I want to update the text view for the linearLayout that was clicked.
I don't know how to get the position of which button(linearLayout) was clicked after the callback.
I got a feeling its something to do with Callback / interface. But I don't know how to use it fully
Code of the LinearLayout is call SearchBar :
EditText et;
Button bt;
LinearLayout ll;
IntentIntegrator _scanner;
public SearchBar(Context c){
et=new EditText(c);
bt=new Button(c);
//et.setHint("WayPoint");
bt.setText("Scan");
_scanner = new IntentIntegrator((Activity) c);
ll=new LinearLayout(c);
setLinearLayout();
bt.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
_scanner.initiateScan();
}
});
et.setLayoutParams(flowLeft());
bt.setLayoutParams(flowRight());
ll.addView(et);
ll.addView(bt);
}
public LinearLayout getSearchBar(){
return ll;
}
Code of the main class in brief:
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.activity_search);
//_scanner = new IntentIntegrator(this);
//button_scan = (Button) findViewById(R.id.button_scan);
ScrollView sv = new ScrollView(this);
ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.VERTICAL);
l2=new LinearLayout(this);
l2.setOrientation(LinearLayout.VERTICAL);
ll.addView(l2);
//testing for searchBar class
SearchBar origin= new SearchBar(this);
origin.setHint("Origin");
origin.setText("me");
sbs.add(origin);
ll.addView(sbs.get(0).getSearchBar());
destin= new SearchBar(this);
destin.setText("destin");
destin.setHint("destination");
destinLayout=destin.getSearchBar();
sbs.add(destin);
ll.addView(destinLayout);
sv.addView(ll);
this.setContentView(sv);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == IntentIntegrator.REQUEST_CODE) { // from Barcode Scanner
if (resultCode == RESULT_OK)
{
IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if (scanResult == null){
//Alert.ShowAlert(this, "Scanning", "Scan Failed");
}else {
String scanned = scanResult.getContents();
//How to get position of which button was fired
}
}
}
}
The function public void onClick(View v) has the View parameter. You can do whatever you want with that including getId() or getParent(). Maybe you want to call v.getParent() and store that in a class variable so that you can access it in onActivityResult?

Trying to create an app which makes lists. To create a new element in my list I want to use another activity. I do it like that:
public void onNewTask(View view)
{
Intent newTask = new Intent(MainActivity.this, NewTaskActivity.class);
MainActivity.this.startActivityForResult(newTask, 0);
}
After returning to the main activity with results like this:
public void onSave(View view){
Intent main = new Intent();
String[] data;
//getting data here//
main.putExtra("New_task", data);
setResult(RESULT_OK, main);
finish();
}
After that, the linear layout does not show any children, though if I debug my code, I can see that the layout still has them inside. I am adding children programmatically, like this:
LinearLayout linearLayout = findViewById(R.id.toDoLayout); //is in OnCreate()
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams //is in OnCreate()
(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
LinearLayout newLayout = new LinearLayout(this);
newLayout.setOrientation(LinearLayout.HORIZONTAL);
TextView newNumberTextView = new LargeTextViewWithMargins(this);
newNumberTextView.setText("Test");
newLayout.addView(newNumberTextView);
linearLayout.addView(newLayout, layoutParams);
And the onActivityResult is now in this form:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
setContentView(R.layout.activity_main);
}
I've found a similar question here. Does anyone know what may cause such a situation and how it is better to overcome it?
As kelvin suggested, I've removed setContenView from activityResult and this helped. However, I do not understand how it works, but it will do for me for now.
setContentView(R.layout.activity_main); sets the XML (Layout ) for your activity when you call setContentView it will inflate the Layout on the Screen. Now when you are calling it again in onActivityResult You are inflating the view again.
Also I would suggest you to use ListView / RecyclerView for showing lists.
Hello I want to have an Add function that allows me to input items to my GridView
For Background: I have a standard GridView and an XML activity (which contains 2 TextView) that I want to convert to my GridView. I also have a custom ArrayAdapter class and custom Word object (takes 2 Strings variables) that helps me do this.
My problem: I want to have an Add button that takes me to another XML-Layout/class and IDEALLY it input a single item and so when the user goes back to MainActivity the GridView would be updated along with the previous information that I currently hard-coded atm. This previous sentence doesn't work currently
Custom ArrayAdapter and 'WordFolder' is my custom String object that has 2 getters
//constructor - it takes the context and the list of words
WordAdapter(Context context, ArrayList<WordFolder> word){
super(context, 0, word);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
View listItemView = convertView;
if(listItemView == null){
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.folder_view, parent, false);
}
//Getting the current word
WordFolder currentWord = getItem(position);
//making the 2 text view to match our word_folder.xml
TextView title = (TextView) listItemView.findViewById(R.id.title);
title.setText(currentWord.getTitle());
TextView desc = (TextView) listItemView.findViewById(R.id.desc);
desc.setText(currentWord.getTitleDesc());
return listItemView;
}
}
Here is my NewFolder code. Which sets contentview to a different XML. it's pretty empty since I'm lost on what to do
public class NewFolder extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_folder_view);
Button add = (Button) findViewById(R.id.add);
//If the user clicks the add button - it will save the contents to the Word Class
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//make TextView variables and cast the contents to a string and save it to a String variable
TextView name = (TextView) findViewById(R.id.new_folder);
String title = (String) name.getText();
TextView descText = (TextView) findViewById(R.id.desc);
String desc = (String) descText.getText();
//Save it to the Word class
ArrayList<WordFolder> word = new ArrayList<>();
word.add(new WordFolder(title, desc));
//goes back to the MainActivity
Intent intent = new Intent(NewFolder.this, MainActivity.class);
startActivity(intent);
}
});
}
In my WordFolder class I made some TextView variables and save the strings to my ArrayList<> object but so far it's been useless since it doesn't interact with the previous ArrayList<> in ActivityMain which makes sense because its an entirely new object. I thought about making the ArrayList a global variable which atm it doesn't make sense to me and I'm currently lost.
Sample code would be appreciative but looking for a sense of direction on what to do next. I can provide other code if necessary. Thank you
To pass data between Activities to need to do a few things:
First, when the user presses your "Add" button, you want to start the second activity in a way that allows it to return a result. this means, that instead of using startActivity you need to use startActivityForResult.
This method takes an intent and an int.
Use the same intent you used in startActivity.
The int should be a code that helps you identify where a result came from, when a result comes. For this, define some constant in your ActivityMain class:
private static final int ADD_RESULT_CODE = 123;
Now, your button's click listener should looks something like this:
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent=new Intent(MainActivity.this, NewFolder.class);
startActivityForResult(intent, ADD_RESULT_CODE);
}
});
Now for returning the result.
First, you shouldn't go back to your main activity by starting another intent.
Instead, you should use finish() (which is a method defined in AppCompatActivity, you can use to finish your activity), this will return the user to the last place he was before this activity - ActivityMain.
And to return some data, too, you can use this code:
Intent intent=new Intent();
intent.putExtra("title",title);
intent.putExtra("desc",desc);
setResult(Activity.RESULT_OK, intent);
where title and desc are the variables you want to pass.
in your case it should look something like this:
public class NewFolder extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_folder_view);
Button add = (Button) findViewById(R.id.add);
//If the user clicks the add button - it will save the contents to the Word Class
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//make TextView variables and cast the contents to a string and save it to a String variable
TextView name = (TextView) findViewById(R.id.new_folder);
String title = (String) name.getText();
TextView descText = (TextView) findViewById(R.id.desc);
String desc = (String) descText.getText();
//Save it to the Word class
ArrayList<WordFolder> word = new ArrayList<>();
word.add(new WordFolder(title, desc));
Intent intent=new Intent();
intent.putExtra("title",title);
intent.putExtra("desc",desc);
setResult(Activity.RESULT_OK, intent);
//goes back to the MainActivity
finish();
}
});
}
You should probably also take care of the case where the user changed his mind and wants to cancel adding an item. in this case you should:
setResult(Activity.RESULT_CANCELLED);
finish();
In your ActivityMain you will have the result code, and if its Activity.RESULT_OK you'll know you should add a new item, but if its Activity.RESULT_CANCELLED you'll know that the user changed their mind
Now all that's left is receiving the data in ActivityMain, and doing whatever you want to do with it (like adding it to the grid view).
To do this you need to override a method called onActivityResult inside ActivityMain:
// Call Back method to get the Message form other Activity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
// check the result code to know where the result came from
//and check that the result code is OK
if(resultCode == Activity.RESULT_OK && requestCode == ADD_RESULT_CODE )
{
String title = data.getStringExtra("title");
String desc = data.getStringExtra("desc");
//... now, do whatever you want with these variables in ActivityMain.
}
}
I need to call a new activity, when a button inside one of my recyclerview row elements is called. Each row item in the list contains 4 buttons, one of which needs to open a new activity which will be used to edit the data in that row.
Here is the code for my button so far:
public void onBindViewHolder(CounterLayoutAdapter.ViewHolder holder, final
int position) {
final Counter counter = counterList.get(position);
//counter is a class which holds the data that will be displayed on one
//row
String comment = counter.getComment();
String name = counter.getCounterName();
int number = counter.getCurrentValue();
//LocalDate modifyDate = counter.getLastModifyDate();
Button up = holder.itemView.findViewById(R.id.buttonUp);
Button down = holder.itemView.findViewById(R.id.buttonDown);
Button reset = holder.itemView.findViewById(R.id.buttonReset);
Button edit = holder.itemView.findViewById(R.id.buttonEdit);
Button delete = holder.itemView.findViewById(R.id.buttonDelete);
// code for 4 other buttons goes here
//
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
Since I need the activity that I open to return user inputted data for me, I am using startActivityForResult. However, as far as I can tell, this will only work inside an actual activity class.
So then I tried passing the mainactivity context to my CounterLayoutAdapter class, where all of my button code is. However, the OnBindViewHolder method still cannot access it there. So I tried to pass the context to OnBindViewHolder, but that doesn't work either, as it won't override the abstract class if i do that..
So, how on earth can I call a new activity here?
Alternatively, if there is some other way to get user input into 4 fields and return that input back to the adapter, without calling an activity, that would work as well.
EDIT: viewholder and layout inflation
public static class ViewHolder extends RecyclerView.ViewHolder implements
View.OnClickListener {
private TextView name;
private TextView comment;
private TextView number;
//private TextView date;
public ViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
comment = itemView.findViewById(R.id.textComment);
name = itemView.findViewById(R.id.textName);
number = itemView.findViewById(R.id.editTextNum);
//date = itemView.findViewById(R.id.textDate);
}
#Override
public void onClick(View view) {}
}
#Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View inflatedView =
LayoutInflater.from(parent.getContext()).inflate(R.layout
.row_layout, parent, false);
return new ViewHolder(inflatedView);
}
You can call startActivityForResult() in adapter class.
Get context in adapter like Context context=holder.up.getContext();
then in your button's OnClickListener do this.
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent=new Intent(context,ActivityYouWantToStart.class);
//Pass any extras if you want to.
((Activity)context).startActivityForResult(intent,REQUEST_CODE);
}
});
Then in your activity (which contain this recyclerView) override onActivityResult like this
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CODE) {//same REQUEST_CODE you used in adapter
if (resultCode == RESULT_OK) {
//Do your thing and get the data you want.
adapter.onDataReady(Data data);//where adapter is your recycler adapter,
//and data is whatever data you want to pass to adapter
//(Data you got from the activityResult, do not confuse it with onActivityResult's parameter 'Intent data')
}
}
}
Finally in your Recycler Adapter class, define onDataReady() function like
public void onDataReady(Data data){
//Update RecyclerView with new data
}
Hope this helps. I once did this, and it works for me. Let me know if you have any problem.
As you see , you do not have to findViewById in onBindViewHolder.
public void onBindViewHolder(CounterLayoutAdapter.ViewHolder holder, final
int position) {
final Counter counter = counterList.get(position);
//counter is a class which holds the data that will be displayed on one
//row
String comment = counter.getComment();
String name = counter.getCounterName();
int number = counter.getCurrentValue();
//LocalDate modifyDate = counter.getLastModifyDate();
holder.edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
}
});
Then you should init edit in ViewHolder constructor.
public ViewHolder(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
comment = itemView.findViewById(R.id.textComment);
name = itemView.findViewById(R.id.textName);
number = itemView.findViewById(R.id.editTextNum);
//date = itemView.findViewById(R.id.textDate);
// init four button
edit = itemView.findViewById(R.id.buttonEdit)
}
As soon as the setOnClickListener executes I want to start another activity and transmit the variable cn.getID() to it. When inside the other activity I want to immidietaly start the method findlocation and give cn.getID() to it.
The method findLocation is not finished yet. The idea is, once it gets the ID of the other activities button, i can search with sqllite in my database for the place it belongs to, get longitude and latitude and tell mapcontroller focus the world map on this point.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.verladestellen);
final DB_Verladestellen db = new DB_Verladestellen(this);
List<DB_Place> placeList = db.getAllDBPlaces();
final LinearLayout layout = (LinearLayout) findViewById(R.id.verladestellen_liste);
for (final DB_Place cn : placeList) {
final LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
Button place = new Button(this);
place.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
place.setText(cn.getName());
place.setId(cn.getID());
row.addView(place);
row.setId(cn.getID());
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) place.getLayoutParams();
params.weight = 1.0f;
place.setLayoutParams(params);
place.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//Here I want to call the method to start the other activity
//and transmit cn.getID().
openMap(null);
}
});
layout.addView(row);
}
}
//The method to start the other activity
public void openMap(View view) {
Intent intent = new Intent(this, UI_MainActivity.class);
startActivity(intent);
}
This is the method from inside the new activity I want to execute immidietaly after it has started:
public void findLocation(View view){
MapView map = (MapView) findViewById(R.id.map);
IMapController mapController = map.getController();
mapController.setZoom(17);
GeoPoint myLocation = new GeoPoint(PLACEHOLDER X , PLACEHOLDER Y);
mapController.animateTo(myLocation);
}
EDIT:
#Murat K. After some edits this is my whole class now:
public class UI_Verladestellen extends AppCompatActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.verladestellen);
final DB_Verladestellen db = new DB_Verladestellen(this);
List<DB_Place> placeList = db.getAllDBPlaces();
final LinearLayout layout = (LinearLayout) findViewById(R.id.verladestellen_liste);
for (final DB_Place cn : placeList) {
final LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
Button place = new Button(this);
place.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT));
place.setText(cn.getName());
place.setId(cn.getID());
row.addView(place);
row.setId(cn.getID());
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) place.getLayoutParams();
params.weight = 1.0f;
place.setLayoutParams(params);
place.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
openMap(cn.getID());
}
});
layout.addView(row);
}
}
public void openMap(int view) {
Intent intent = new Intent(UI_Verladestellen.this, UI_MainActivity.class);
intent.putExtra("findLocation", 1);
startActivity(intent);
}
}
And this is the getIntent of my onCreate method in UI_MainActivity:
int i = getIntent().getIntExtra("findlocation", 999);
if(i == 1){
findLocation(i);
}
As I edited into my earlier comment, i cant see where my Button-ID is recieved. At first i thought i would be my ID, but that wouldnt work, since The Button ID can be every number from 1 to n.
You can achieve this with an Intent e.g.
Intent i = new Intent(BaseActivity.this, YourSecondActivity.class);
intent.putExtra("METHOD_TO_CALL", 1);
startActivity(i);
and in your onCreate() method of the starting Activity you check for it.
#Override
public void onCreate(Bundle savedInstanceState) {
int i = getIntent().getIntExtra("METHOD_TO_CALL", 999);
if(i == 1){
callMethod(i);
}
EDIT:
//The method to start the other activity
public void openMap(View view) {
Intent intent = new Intent(this, UI_MainActivity.class);
intent.putExtra("METHOD_TO_CALL", 1); // the 1 is a example, put your ID here
startActivity(intent);
}
Step #1: Use putExtra() to add your ID value to the Intent that you use with startActivity()
Step #2: In the other activity, call getIntent() in onCreate() to retrieve the Intent used to create the activity instance. Call get...Extra() (where ... depends on the data type) to retrieve your ID value. If the ID value exists, call your findLocation() method.
It depends on how you want it to work. If you only want it to execute when the activity is created (when it starts or screen rotates) then call the method within the activities onCreate method. If you want it called whenever the user returns to that activity which can include them leaving the app and coming back to it sometime later then onResume would be a better spot for it. Calling the method from either should work as you hope though.
I also recommend looking over the Activity lifecycle as that will help you a lot in the future.
I have just started Android Studio and am also a little new to java, so please excuse the inefficient code.
Anyway, when I click on the button on the main activity on my app to take the user to the activity that I want to display the images, my app stops working and it throws an OutOfMemoryError.
Here is MainActivty.java:
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button presidentQuizButton = (Button) findViewById(R.id.presidentQuizButton);
Button reviewPresidentsButton = (Button) findViewById(R.id.reviewPresidentsButton);
presidentQuizButton.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v){
//when button is clicked, do something
}
});
reviewPresidentsButton.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v){
//when button is clicked, do something
startActivity(new Intent(MainActivity.this, presidentReviewActivity.class));
}
});
}
Here is presidentReviewActivity.java:

And here is most of the error log:
http://imgur.com/xzFfPrq
Instead of store all the drawable content in an array. You can actually just store the resource id in a array.
replace private Drawable [] drawables = null; with private int[] drawableids
replace drawables = new Drawable[]{...} to drawableids = new int[]{...}
replace
drawable = drawables[presidentNumber];
imageView.setImageDrawable(drawable);
to
drawable = getResource().getDrawable(drawableids[presidentNumber]);
imageView.setImageDrawable(drawable);
Try to change as above steps and try again.
The nullpointerexception may be caused by you did not init the drawableids array or you are still using the drawables array instead of drawableids.
you are trying to load large size images directly into memory which causes out of memory exceptions,this issue is discussed in details and a nice solution is given in developers site
