Parsing user input in edittext field of the type date and check for correct date format

I am working on an Android app and processing user input from an edittext field. I want to check if the user entered a correct date format; however, for reasons that I don´t understand, I need to convert the type of the edittext type date to a string and then convert it back to a float number, to check against a regular expression and that is not working correctly.

Actually, why do I need to read the input in an input type of date, cast it to an integer and check if this integer value has the right format? Isn`t there any other, better way? I just want to check that the users does not enter more than 6 digits and that these digits have the right format.
Any hints or help would be appreciated, thanks!

I just want to check that the users does not enter more than 6 digits and that these digits have the right format.
Lets say, required format is dd-mm-yy
Use regex - \d{2}-\d{2}-\d{2}
For example,
if (inputSTR.matches("\\d{2}-\\d{2}-\\d{2}")) {
// input matches to required pattern
} else {
// Show error msg
}

First, Tim Biegeleisen’s comment that you should use a date picker rather than an EditText is probably well worth considering.
Anyway, if you get your date as a string, the recommended way of validating it is to try to parse it into a date and see if you succeed — not through a regular expression. And you certainly shouldn’t try to parse it as an integer, that is bound to fail. My code would go something like:
String ss = date.getText().toString();
if (ss.isEmpty()) {
// tell the user to enter something
} else {
try {
LocalDate.parse(ss);
// tell the user the format is right
} catch (DateTimeParseException dtpe) {
// tell the user that this is not a valid date
}
}
I am assuming that your date should be in the format yyyy-MM-dd. This is the default parse format for LocalDate, so it’s rather straightforward if you know about exceptions and try/catch constructs. If you require a different format, you will need to specify it through a DateTimeFormatter.
The advantage over the regex approach is it gives you much better validation. ^\\d{4}-\\d{2}-\\d{2}$ will accept 2017-29-11 and 2017-11-92 as dates, where the parsing approach will catch if the month is not 1 through 12 or the day-of-month is not within the number of days in that month.
Now you are at it, if you need to keep your date (likely since you asked the user to enter it), keep it as a LocalDate object rather than a string. This will prepare your app for doing all sorts of operations on the date. Whenever you need a string, just use LocalDate.toString(). Or use a DateTimeFormatter if you want the string as for example “Sunday November 19, 2017” or even in German or some other language.
I am using java.time, the modern Java date and time API also known as JSR-310. Unfortunately this doesn’t come with most Android devices yet. The solution is the ThreeTenABP, the backport of JSR-310 to Android. I encourage you to get this and start coding.

Are there additional buttons for ExoPlayer for Android?

Are there any additional libraries that contain button graphics for the Android ExoPlayer found here. There are the options for fast forward, rewind, play, pause and a few others but there are no options for a mute/unmute or fast forward 2x/4x/etc. I want those options as I build an alternative UI.

Change the Media Controller to provide the options that going to mute/unmute or fast forward. For adding these view(Buttons) in to the view of controller then for that customize the media controller. Check this also Custom Media Controller

What am i doing wrong and how can i fix this.

I was able o fix this by using an android handler object instead :
import android.os.Handler;
public class CustomNumberPicker extends LinierLayout{
private final Handler handler = new Handler
private void init(Context context){
minus_button.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
if (!plus_held) {
minus_held = true;
handler.post(new autoValueChanger());
}
return false;
}
});
minus_button.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (!plus_held && (event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL)) {
minus_held = false;
}
return false;
}
});
}
private class autoValueChanger implements Runnable {
/**
* Starts executing the active part of the class' code. This method is
* called when a thread is started that has been created with a class which
* implements {#code Runnable}.
*/
#Override
public void run() {
if (minus_held) {
if (current_value > MIN) {
decreaseValue();
handler.postDelayed(new autoValueChanger(), 100);
}else{
minus_held = false;
}
}else if(plus_held) {
if (current_value < MAX){
increaseValue();
handler.postDelayed(new autoValueChanger(),100);
}else {
plus_held = false;
}
}
}
}

I searched for a lot of codes for onlistview scrolling, but didn't know how to implement it. The problem is, when I call my asynctask, I have an url param,
like new getArticles("http://example.com").execute();
I want to implement an onscrolllistener, but it goes like this, my param is usually set to: http://www.example.com/category/categoryname/, so the second page goes like http://www.example.com/category/categoryname/page/2/, the third one goes http://www.example.com/category/categoryname/page/3/ and so on. Each page has got 7 items that need to be parsed.
How could I implement onscrolllistener, because of the url param?
Thanks in advance.

Base on this link, I have written following solution to add elements ( 30 elements at a time, i.e page size = 30) to listview asynchronously.
Create a class named EndlessListView as follows:
public class EndlessListView extends ListView implements OnScrollListener {
private View footer;
private boolean isLoading;
private EndlessListener listener;// listner
private EndlessAdapter endlessAdapter;// adapter.
private int maxNoOfElement;
public EndlessListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
this.setOnScrollListener(this);
}
public EndlessListView(Context context, AttributeSet attrs) {
super(context, attrs);
this.setOnScrollListener(this);
}
public EndlessListView(Context context) {
super(context);
this.setOnScrollListener(this);
}
public void setListener(EndlessListener listener) {
this.listener = listener;
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if (getAdapter() == null)
return;
if (getAdapter().getCount() == 0 || getAdapter().getCount() <= 5)
return;
int l = visibleItemCount + firstVisibleItem;
if (l >= totalItemCount && !isLoading) {
// It is time to add new data. We call the listener
Log.e("LOAD", "DATA");
isLoading = true;
listener.loadData();
}
}
public void setMaxElemnt(int maxNoOfElement) {
this.maxNoOfElement = maxNoOfElement;
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
public void setLoadingView(int resId) {
LayoutInflater inflater = (LayoutInflater) super.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
footer = (View) inflater.inflate(resId, null);
this.addFooterView(footer);
}
public void setAdapter(EndlessAdapter adapter) {
super.setAdapter(adapter);
this.endlessAdapter = adapter;
}
public void addNewData(List<Integer> data) {
endlessAdapter.setData(data);
endlessAdapter.notifyDataSetChanged();
isLoading = false;
}
public static interface EndlessListener {
public void loadData();
}
}
After this we have to create the adapter for it,called
EndlessAdapter
public class EndlessAdapter extends BaseAdapter {
private List<Integer> mIntegers;
private Context context;
public EndlessAdapter(Context context) {
this.context = context;
}
public void setData(List<Integer> mIntegers) {
this.mIntegers = mIntegers;
}
#Override
public int getCount() {
if (mIntegers == null)
return 0;
return mIntegers.size();
}
#Override
public Integer getItem(int index) {
if (mIntegers == null) {
return null;
} else {
return mIntegers.get(index);
}
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return 0;
}
class ViewHolder {
TextView textView;
}
#Override
public View getView(int index, View view, ViewGroup viewGroup) {
ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
view = ((LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE))
.inflate(R.layout.rows, viewGroup, false);
holder.textView = (TextView) view.findViewById(R.id.mtext);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
holder.textView.setText(getItem(index) + "");
return view;
}
}
Now in xml of the activity we could use EndlessListView(in com.example.stackoverflow package) as follows :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<com.example.stackoverflow.EndlessListView
android:id="#+id/endlessListView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</RelativeLayout>
After this step we need to make following change in the MainActivity
public class MainActivity extends Activity implements EndlessListener {
private EndlessAdapter adapter;
private EndlessListView endlessListView;
private List<Integer> data;
private int gStartIndex = 30;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
endlessListView = (EndlessListView) findViewById(R.id.endlessListView);
adapter = new EndlessAdapter(this);
data = new ArrayList<Integer>();
endlessListView.setLoadingView(R.layout.footer);
// endlessListView.showFooter();
endlessListView.setListener(this);
endlessListView.setAdapter(adapter);
gStartIndex = 0;
fillData(gStartIndex);
}
private void fillData(int startIndex) {
new AsyncLoadData().execute(startIndex);
}
#Override
public void loadData() {
fillData(gStartIndex);
}
private class AsyncLoadData extends AsyncTask<Integer, Integer, Void> {
#Override
protected Void doInBackground(Integer... params) {
int gendIndex = params[0] + 30;
gStartIndex = gendIndex;
/***
* Here you could add your n/w code. To simulate the n/w comm. i am
* adding elements to list and making it sleep for few sec.
* */
for (int i = params[0]; i < gendIndex; i++) {
publishProgress(i);
}
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
data.add(values[0]);
}
#Override
protected void onPostExecute(Void result) {
endlessListView.addNewData(data);
}
}
}

This custom ScrollListView that I just found has OnBottomReachedListener which you can implement from your Activity or Fragment and receive events when user hits the bottom of the page. You would also need to track the current page and when bottom is hit to download the next page. The latest data should be added to your existing ArrayList and you should call notifyDataSetChanged() on your adapter so ListView can render the new data. You don't have to create new adapter, you just need to update the data source which is your ArrayList.
If you support orientation change you would must to save in onSaveInstanceState() your current page number so when Activity or Fragment is recreated it can continue from correct page. And you would have to keep the ArrayList data source safe of configuration changes because you don't want to downloaded it again. I would suggest using the Fragment with setRetainInstance() set to true to persist ArrayList.
Here is my custom code for keeping data around using RetainFragment:
/**
* A simple non-UI Fragment that stores a single Object
* and is retained over configuration changes.
*/
public class RetainFragment<E extends Object> extends Fragment {
/** Object for retaining. */
private E mObject;
/**
* Empty constructor as per the Fragment documentation
*/
public RetainFragment() {}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Make sure this Fragment is retained over a configuration change
setRetainInstance(true);
}
/**
* Store a single object in this Fragment.
*
* #param object The object to store
*/
public void setObject(E object) {
mObject = object;
}
/**
* Get the stored object.
*
* #return The stored object
*/
public E getObject() {
return mObject;
}
}
Example of RetainFragment usage in your Activity:
FragmentManager fm = getFragmentManager();
mRetainFragment = (RetainFragment<ArrayList>) fm.findFragmentByTag(RETAIN_FRAG);
if (mRetainFragment == null) {
mRetainFragment = new RetainFragment<>();
mRetainFragment.setObject(new ArrayList());
fm.beginTransaction().add(mRetainFragment, RETAIN_FRAG).commit();
}
ArrayList yourArrayList = mRetainFragment.getObject();
// Now your ArrayList is saved accrossed configuration changes

here what you want fist add onscrolllistner to listview
boolean loading_flage = false;
yourlistview.setOnScrollListener(new OnScrollListener() {
#Override
public void onScrollStateChanged(
AbsListView view,
int scrollState) {
// TODO Auto-generated method stub
}
#Override
public void onScroll(AbsListView view,
int firstVisibleItem,
int visibleItemCount,
int totalItemCount) {
final int lastItem = firstVisibleItem
+ visibleItemCount;
if ((lastItem == totalItemCount)
& loading_flage == false) {
//this to prevent the list to make more than one request in time
loading_flage = true;
//you can put the index for your next page here
loadMore(int page);
}
}
});
and then in loading more after loading the page set the loading with false and parse the data add it to the data that you aleardy have
//notify the adapter
adapter.notifyDataSetChanged();
loading_flage = false;

You can achieve by adding the scrolllistener on listview and check condition if list last visible item is last in ArrayList then call the asynctask with incremented page number and update the listview,mean while add the view on listview and after getting the result from server remove the loading more view from the listview like this -
AndroidListViewLoadMoreActivity.java
public class AndroidListViewLoadMoreActivity extends Activity {

First, you need a OnScrollListener method like this:
private OnScrollListener onScrollListener() {
return new OnScrollListener() {
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
int threshold = 1;
int count = listView.getCount();
if (scrollState == SCROLL_STATE_IDLE) {
if (listView.getLastVisiblePosition() >= count - threshold && pageCount < 2) {
Log.i(TAG, "loading more data");
// Execute LoadMoreDataTask AsyncTask
//It reached ListView bottom
getDataFromUrl(url_page2);
}
}
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount,
int totalItemCount) {
}
};
}
set List View scroll listener by listView.setOnScrollListener(onScrollListener());

How can add a touchable image view inside of edit text?

I need to add a touchable image view inside an edit text like ms word screen.How can we design an android layout screen for this purpose?I have tried the code shown below:
public class edittext extends EditText
{
public String defaultValue = "";
final Drawable imgX = getResources().getDrawable(android.R.drawable.presence_offline ); // X image
private Html.ImageGetter imageGetter;
public edittext(Context context, AttributeSet attrs)
{
super(context, attrs);
init();
// TODO Auto-generated constructor stub
}
public edittext(Context context, AttributeSet attrs, int defStyle)
{
super(context, attrs, defStyle);
init();
// TODO Auto-generated constructor stub
}
public edittext(Context context)
{
super(context);
init();
// TODO Auto-generated constructor stub
}
void init() {
// Set bounds of our X button
imgX.setBounds(0, 0, imgX.getIntrinsicWidth(), imgX.getIntrinsicHeight());
// There may be initial text in the field, so we may need to display the button
manageClearButton();
edittext.this.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
edittext et = edittext.this;
// Is there an X showing?
if (et.getCompoundDrawables()[2] == null) return false;
// Only do this for up touches
if (event.getAction() != MotionEvent.ACTION_UP) return false;
// Is touch on our clear button?
if (event.getX() > et.getWidth() - et.getPaddingRight() - imgX.getIntrinsicWidth()) {
et.setText("");
edittext.this.removeClearButton();
}
return false;
}
});
edittext.this.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
edittext.this.manageClearButton();
}
public void afterTextChanged(Editable arg0) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
});
}
void manageClearButton() {
if (this.getText().toString().equals("") )
removeClearButton();
else
addClearButton();
}
void addClearButton() {
this.setCompoundDrawables(this.getCompoundDrawables()[0],
this.getCompoundDrawables()[1],
imgX,
this.getCompoundDrawables()[3]);
}
void removeClearButton() {
this.setCompoundDrawables(this.getCompoundDrawables()[0],
this.getCompoundDrawables()[1],
null,
this.getCompoundDrawables()[3]);
}
}
if anyone knows about it please help me with thanks.

I am doing it like that. The Drawable will be at the right side of the EditText. Please try the code.
EditText contactLine = new EditText(getActivity());
Drawable drawable = getActivity().getResources().getDrawable(...);
drawable.setBounds(new Rect(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight()));
contactLine.setCompoundDrawables(null, null, drawable, null);
contactLine.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
Drawable co = v.getCompoundDrawables()[2];
if (co == null) {
return false;
}
if (event.getAction() != MotionEvent.ACTION_DOWN) {
return false;
}
if (event.getX() > v.getMeasuredWidth() - v.getPaddingRight()
- co.getIntrinsicWidth()) {
whatYouWantToDo();
return true;
} else {
return false;
}
}
});

or you can simply use ImageButton , example :
public void addListenerOnImageButton() {
imageButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// called when imageButton Clicked
}
});}

May be you could do that in a layout using RelativeLayout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/et1"
android:layout_width="200dp"
android:layout_height="100dp"
android:clickable="false"
android:focusable="false"
android:background="#drawable/ic_action_search"/>
<ImageView
android:id="#+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/et1"
android:paddingLeft="5dp"
android:background="#drawable/ic_launcher"
/>
</RelativeLayout>

For a moveable view in a RelativeLayout, you ca do this. The DragView can be a ImageView.
View DragView;
private boolean inDrag;
int xDragTouchOffset, yDragTouchOffset;
#Override
public boolean onTouchEvent(View View, MotionEvent event) {
final int action = event.getAction();
final int x = (int) event.getX();
final int y = (int) event.getY();
boolean result = false;
if (action == MotionEvent.ACTION_DOWN)
inDrag = true;
xDragTouchOffset = x;
yDragTouchOffset = y;
result = true;
} else if (action == MotionEvent.ACTION_MOVE && inDrag == true) {
setDragImagePosition(x, y);//HERE YOU HANDLE THE POSITION OF YOUR VIEW
result = true;
} else if (action == MotionEvent.ACTION_UP && inDrag ==true) {
inDrag = false;
result = true;
}
return result;
}
private void setDragImagePosition(int x, int y){
RelativeLayout.LayoutParams lp = (RelativeLayout.LayoutParams) DragView
.getLayoutParams();
lp.setMargins(x - xDragImageOffset - xDragTouchOffset, y
- yDragImageOffset - yDragTouchOffset, 0, 0);
dragImage.setLayoutParams(lp);
}
