How to prevent the activity from loading twice on pressing the button

Question

I am trying to prevent the activity from loading twice if I press the button twice instantly after the first click.

I have an activity which loads on click of a button, say

 myButton.setOnClickListener(new View.OnClickListener() {       public void onClick(View view) {        //Load another activity     } }); 

Now because the activity to be loaded has network calls, it takes a little time to load (MVC). I do show a loading view for this but if I press the button twice before that, I can see the activity being loaded twice.

Do any one know how to prevent this?

Answer 1

Add this to your Activity definition in AndroidManifest.xml...

android:launchMode = "singleTop" 

For example:

<activity             android:name=".MainActivity"             android:theme="@style/AppTheme.NoActionBar"             android:launchMode = "singleTop"/>

In the button's event listener, disable the button and show another activity.

    Button b = (Button) view;     b.setEnabled(false);      Intent i = new Intent(this, AnotherActitivty.class);     startActivity(i); 

Override onResume() to re-enable the button.

@Override     protected void onResume() {         super.onResume();          Button button1 = (Button) findViewById(R.id.button1);         button1.setEnabled(true);     }
