Android: How to restart an Activity

Question

I'm trying to restart an Activity in my App, but I have some problems.

When I use recreate();, the activity doesn't completely restart, the EditTexts don't get empty.

I also tried this code:

Intent myIntent = getIntent();
myIntent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
finish();
startActivity(myIntent);

BUT:

At the start, my Activity have an EditText and it get auto-focus. I'm using this code to open Keyboard when focus, and close when lost focus:

txtNumber.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
         if (hasFocus) {
             imm.showSoftInput(txtNumber, InputMethodManager.SHOW_IMPLICIT);
         } else {
             imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
         }
    }
});

But it doesn't works when Activity starts, so i had to add android:windowSoftInputMode="stateVisible" to the AndroidManifest.xml.

The problem is that: the 2nd code (for restart the activity) ignore this, and don't open the Keyboard at the start.

How can I open the Keyboard at the Activity Start programmatically? Or how can I completely restart an activity using recreate();?

Sorry for bad english, I hope you understand.

recreate() and call finish(). for older apis (I guess lower 13(?)) startActivity(new Intent(this, getIntent()) and call finish(); and you may put a bundle into the intent, then receive it in onCreate and use it to update/ set up your UI — Martin Pfeffer, Jan 20 '16 at 07:55
try inside oncreate -- (getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);) from here -- http://stackoverflow.com/questions/5593053/open-soft-keyboard-programmatically — Tasos, Jan 20 '16 at 07:57
Try to txtNumber.requestFocus() after activity restart at onResume — Allen Chan, Jan 20 '16 at 07:58
@MartinPfeffer `recreate()` and `finish()` just close the activity. — Julián Pera, Jan 20 '16 at 07:59
@JuliánPera sorry, my bad... recreate does invoke finish() already.. — Martin Pfeffer, Jan 20 '16 at 08:03
@MartinPfeffer With `recreate()`, the Activity's EditTexts don't get empty. @Tasos Same result that using `android:windowSoftInputMode="stateVisible"`. @AllenChan Nothing, i also tried turning on the focuseable attribute in the layout. — Julián Pera, Jan 20 '16 at 08:15
@TargetApi(Build.VERSION_CODES.CUPCAKE) public void changeKeyboardState() { InputMethodManager imm = (InputMethodManager) getContext().getSystemService(Context.INPUT_METHOD_SERVICE); imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); } — Martin Pfeffer, Jan 20 '16 at 09:02

I tried that. Look at the 2nd code in the original post. – Julián Pera Jan 20 '16 at 08:05

add focusable to your EditText and call requestFocus() when you need to show the the keyboard.

I guess that EditText is focuseable by default. Anyway, i added `focusable`/`focusableInTouchMode` and put `requestFocus()` in `onResume`, but nothing. Keyboard doesn't show up. – Julián Pera Jan 20 '16 at 09:45

What about this?:

Intent i = getBaseContext().getPackageManager().getLaunchIntentForPackage(getBaseContext().getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);

This just close the activity. – Julián Pera Jan 20 '16 at 08:24
I dont know. Im testing this code right now, and it just close the activity. Maybe because the button is inside a DialogAlert? – Julián Pera Jan 20 '16 at 08:31
The interesting part is, i am using above codes with a `Dialog`(and it's working).let us know your implementation if you want, but above codes are working in my application. – ʍѳђઽ૯ท Jan 20 '16 at 08:35
