starting the same activity with button in android

Question

Is it possible to start the same activity on button click. I have a button in my MainActivity and I want that when I click that button the current Activity (MainActivity) restarts (start again) ? Thanks in Advance.

Solution 1

Try this :)

Button buttonOne = (Button) findViewById(R.id.button1);
buttonOne.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
       Intent intent = new Intent(MainActivity.this,
                        MainActivity.class);

                startActivity(intent);
}
 });

But i dont understand why you wanna do this :P

Solution 2

The only way to do this is to launch the Intent to that Activity again. But, I don't see why you would want to do that, jut refresh the content of the Activity calling the same activity within that activity.. is redundant and doesn't make sense.

Solution 3

If you just want to reload the activity, for whatever reason, you can use this.recreate(); where this is the Activity.

I couldn't get solved this, that's why I thought it other way.

Its always better to solve the core problem than patch a symptom.

Its working , but when I press backbutton the app crashes why ?

use finish(); after startActivity(intent); so that it will close current activity and disply the new one

This is never a good practice. Instead you should startActivity() for the same activity and call finish() in the current one.
