I have been able to save one entry to shared preferences and for it to display in a list view on another view but I am wanting to add multiple entries and them to display in the listview too. I thought I had the correct code but it doesn't see mto have changed anything. My intent is a favourites list, I take the entry data from one view and display it in another view.
SingleView Activity:
SharedPreferences.Editor fd;
SharedPreferences FeedPref;
private ArrayList<String> addArray = new ArrayList<>();
txt = (TextView) findViewById(R.id.name);
add = (Button) findViewById(R.id.btnAdd);
FeedPref = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
fd = FeedPref.edit();
add.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String message = txt.getText().toString();
if (addArray.contains(message)) {
Toast.makeText((getBaseContext()), "Plant Already Added", Toast.LENGTH_LONG).show();
} else {
addArray.add(message);
FeedPref = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
fd = FeedPref.edit();
fd.putInt("array_size", addArray.size());
for (int i = 0; i < addArray.size(); i++) {
fd.putString("Status_" + i, addArray.get(i));
}
fd.commit();
Toast.makeText((getBaseContext()), "Plant Added", Toast.LENGTH_LONG).show();
}
}
});

My code used to replace the previous entries and I realized I needed to use different keys for storing in shared preferences. Now my code does not output anything in the listview. please help
Java code where I ask for information about the person (name, favcolor, favfood)
public class personInfo extends AppCompatActivity {
EditText editText_name;
EditText editText_favfood;
EditText editText_favcolor;
Button button_save;
static int count = 0;
SharedPreferences sharedPreferences;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_personinfo);
Log.d(MainActivity.class.getSimpleName(), "onCreate");
editText_name = (EditText) findViewById(R.id.editText_name);
editText_favcolor = (EditText) findViewById(R.id.editText_favcolor);
editText_favfood = (EditText) findViewById(R.id.editText_favfood);
button_save = (Button) findViewById(R.id.button_save);
button_save.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
count++;
SharedPreferences sharedPreferences = getSharedPreferences("ENTRIES", 0);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("name" + count, editText_name.getText().toString());
editor.putString("favcolor" + count, editText_favcolor.getText().toString());
editor.putString("favfood" + count, editText_favfood.getText().toString());
editor.apply();
editor.putInt("numOfEntries", count);
Intent it = new Intent(personInfo.this, listOfPeople.class);
startActivity(it);
}
});
}
}
Java code, page that is supposed to display the entries
public class listOfPeople extends AppCompatActivity {
ListView listView;
ArrayList<listEntry> list = new ArrayList<>();
listEntry le;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_list);
listView = (ListView) findViewById(R.id.listView_persons);
SharedPreferences sharedPreferences = getSharedPreferences("ENTRIES", MODE_PRIVATE);
int count = sharedPreferences.getInt("numOfEntries", 0);
for(int i = 1; i <= count; i++){
String nameValue = sharedPreferences.getString("name" + i, "");
String favcolorValue = sharedPreferences.getString("favcolor" + i, "");
String favfoodValue = sharedPreferences.getString("favfood" + i, "");
le = new listEntry(nameValue, favcolorValue, favfoodValue);
list.add(le);
}
personListAdapter adapter = new personListAdapter(this, R.layout.entryrow, list);
listView.setAdapter(adapter);
}
}
You are applying (saving) preferences before putting count
editor.apply();
editor.putInt("numOfEntries", count);
Just put before applying
editor.putInt("numOfEntries", count);
editor.apply();
call editor.apply() after editor.putInt("numOfEntries", count);
editor.putInt("numOfEntries", count);
editor.apply();
I am a beginner developer who is studying Android.
The function I want to develop is "Save the data entered in EditText as JSON, save it as SharedPreference, and output it to ListView".
To save it as SharedPreference is OK, but, To output it to ListView is not working now.
MainActivity.java:
public class MainActivity extends AppCompatActivity {
private ListView listView;
private Button save_btn;
private ArrayList<List> data = new ArrayList<List>();
ListAdapter adapter;
String title="";
String info="";
int img = R.drawable.man;
String jsondata;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView) findViewById(R.id.listView);
save_btn = (Button) findViewById(R.id.button1);
loadArrayList(getApplicationContext());
adapter = new ListAdapter(this, R.layout.row, data);
listView.setAdapter(adapter);
registerForContextMenu(listView);
save_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
View dlgview = View.inflate(MainActivity.this, R.layout.adds, null);
//adds.xml
final EditText et_title = (EditText) dlgview.findViewById(R.id.editText1);
final EditText et_info = (EditText) dlgview.findViewById(R.id.editText2);
ImageView img1 = (ImageView) dlgview.findViewById(R.id.imageView2);
AlertDialog.Builder dlg = new AlertDialog.Builder(MainActivity.this);
dlg.setTitle("ADD");
dlg.setView(dlgview);
dlg.setNegativeButton("Save", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
JSONObject jsonObject = new JSONObject();
JSONArray jsonArray = new JSONArray();
try{
jsonObject.put("title", et_title.getText().toString());
jsonObject.put("info", et_info.getText().toString());
jsonObject.put("image",img);
jsonArray.put(jsonObject);
} catch (JSONException e){
e.printStackTrace();
}
jsondata = jsonArray.toString();
saveArrayList();
adapter.notifyDataSetChanged();
}
});
dlg.setPositiveButton("Cancel",null);
dlg.show();
}
});
}//End of onCreate
private void saveArrayList(){
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = sharedPrefs.edit();
editor.putString("jsonData", jsondata);
Log.i("moi","get Data test : " + "jsonData");
editor.apply();
}
private void loadArrayList(Context context){
SharedPreferences sharedPrefs2 = PreferenceManager.getDefaultSharedPreferences(context);
int size = sharedPrefs2.getInt("appreciation_size",0);
String strJson = sharedPrefs2.getString("jsonData", "fail");
Log.i("moi","get SharedPreferences test : " + strJson);
if (strJson != "fail")
{
try {
JSONArray response = new JSONArray(strJson);
for (int i=0; i<size; i++)
{
JSONObject jsonobject = response.getJSONObject(i);
title = jsonobject.getString("title");
Log.i("moi","title test : " + "title");
info = jsonobject.getString("info");
Log.i("moi","info test : " + "info");
data.add(new List(title, info, img));
}
adapter = new ListAdapter(getApplicationContext(), R.layout.row, data);
listView.setAdapter(adapter);
} catch (JSONException e){
e.printStackTrace();
}
}
}
}//End of class
Because you just called loadArrayList() once in onCreate(). That means your data in adapter just changes once.
you call adapter.notifyDataSetChanged() but this method doesnt callloadArrayList()`.
so try to save new json into data in onClick()
Try to remove your code:
adapter = new ListAdapter(this, R.layout.row, data);
listView.setAdapter(adapter);
in CreateView.
I think you set adapter listview double.
i hope that helps you.. thanks
I can transfer my array-data from an activity to the other, but not my string-data, and I don't know why.
This is my mainActivity:
protected void onClickCityBreak(View v) {
persons = (EditText) findViewById(R.id.txtPerson);
days = (EditText) findViewById(R.id.txtDays);
String p = persons.toString();
String d = days.toString();
String [] arrayCityBreak = getResources().getStringArray(R.array.citybreak);
Intent myintent = new Intent(MainActivity.this, TripActivity.class);
myintent.putExtra("PERSONS", p);
myintent.putExtra("DAYS", d);
myintent.putExtra("PLACES",arrayCityBreak);
startActivity(myintent);
}
This is my other activity I am sending to:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_trip);
String person = getIntent().getStringExtra("PERSONS");
String day = getIntent().getStringExtra("DAYS");
TextView txtPerson = (TextView) findViewById(R.id.txtViewPersons);
txtPerson.setText("Persons travelling: " + person);
TextView txtDay = (TextView) findViewById(R.id.txtViewDays);
txtDay.setText("Days of traveling: " + day);
String[] arrayCityBreak = getIntent().getStringArrayExtra("PLACES");
ArrayAdapter<String> adapterCityBreak = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayCityBreak);
ListView myview = (ListView) findViewById(R.id.lstView);
myview.setAdapter(adapterCityBreak);
}
I get this on my TextView in the application:
android.support.v7.widget.AppCompactEditText{13e7726VFED...CL. ........563,56....#7f0c0059 app:id/txtDays\
The same for txtPerson.
I have also tried using Bundle
Getting the content of an EditText should be done in this way :
String p = persons.getText().toString();
String d = days.getText().toString();
Also if you have another problems with putExtra, you can do something like this:
MainActivity:
protected void onClickCityBreak(View v) {
persons = (EditText) findViewById(R.id.txtPerson);
days = (EditText) findViewById(R.id.txtDays);
String p = persons.getText().toString();
String d = days.getText().toString();
String [] arrayCityBreak = getResources().getStringArray(R.array.citybreak);
Intent myintent = new Intent(MainActivity.this, TripActivity.class);
AnotherActivityClass secondactivity = new AnotherActivityClass();
secondactivity.persons = p;
secondactivity.days = d;
secondactivity.places = arrayCityBreak;
startActivity(myintent);
}
Create public string persons and days, also create public String[] in SecondActivity:
public String days;
public String persons;
public String [] places;
And then in SecondActivity use this values:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_trip);
TextView txtPerson = (TextView) findViewById(R.id.txtViewPersons);
txtPerson.setText("Persons travelling: " + person);
TextView txtDay = (TextView) findViewById(R.id.txtViewDays);
txtDay.setText("Days of traveling: " + day);
ArrayAdapter<String> adapterCityBreak = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, arrayCityBreak);
ListView myview = (ListView) findViewById(R.id.lstView);
myview.setAdapter(adapterCityBreak);
}
I am developing an app. In it I'm using a listview. When I click on list item, it should go to next activity, i.e ProfileActivity2.java. It works fine, but in this ProfileActivty2 there is a button at the bottom and when I click on this button my app gets crashed and stopped in listview page. And shows the error java.lang.Throwable: setStateLocked in listview layout file i.e At setContentView. How do I solve this error?

I think the error is at this line inside btn.setOnClickListener of getview block just use startActivity(intent);
Here i have declared the product class variables and assigned it.
product.java
public class Product {
String[] name= new String[100];
int price;
int image;
boolean box;
Product(String[] _describe, int _price, int _image, boolean _box) {
name = _describe;
price = _price;
image = _image;
box = _box;
}
}
This is my product class. What should i change in the above coding??
public class MainActivity extends Activity {
String[] data =new String[] {"no:1","no:2","no:3","no:4","no:5","no:6"};
String[] columnTags = new String[] {"ProcessName", "IpItem", "IpColor", "OpItem","OpColor", "PlanQty", "DcQty", "RecQty", "RtQty"};
ArrayList products = new ArrayList();
ListAdapter1 boxAdapter;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fillData();
boxAdapter = new ListAdapter1(this, products);
ListView lvMain = (ListView) findViewById(R.id.lvMain);
lvMain.setAdapter(boxAdapter);
}
void fillData() {
for (int i = 0; i <= 20; i++) {
products.add(new Product(columnTags, i * 100,i * 553
, false));
}
}
public void showResult(View v) {
String result = "Selected Product are :";
int totalAmount=0;
for (Product p : boxAdapter.getBox()) {
if (p.box){
result += "\n" + p.name;
totalAmount+=p.image;
}
}
String total="Total="+totalAmount;
// Toast.makeText(this, result+"\n"+"Total Amount:="+totalAmount, Toast.LENGTH_LONG).show();
Bundle bundle=new Bundle();
bundle.putString("res",result);
bundle.putString("tot",total);
Intent intent = new Intent(MainActivity.this,MainActivity2Activity.class);
intent.putExtras(bundle);
startActivity(intent);
}
}
The first parameter of your add() requires a String[] and you are passing it a String.
Just change ,
products.add(columnTags[i],i*100,i*553,false)
to
products.add(columnTags,i*100,i*553,false)
Also do the following,
for(...)
{
String temp = columnTags[i];
products.add(temp,i*100,i*553,false)
}
EDIT
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
fillData();
ArrayAdapter boxAdapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, new ArrayList<String>(Arrays.asList(products.name)));
ListView lvMain = (ListView) findViewById(R.id.lvMain);
lvMain.setAdapter(boxAdapter);
}
void fillData() {
String temp;
for (int i = 0; i <columnTags.length; i++) {
temp = columnTags[i];
products.add(new Product(temp, i * 100,i * 553, false));
}
}
