- Android not provided double tap supported events so i have generated manually using handler.
- handler provided using postDelayed() method to delay post to time set by developer.
- delay time set in milliseconds and 1000 milliseconds == 1 second.
public class MainActivity extends Acitivity{
int count =0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public void onBackPressed() {
// TODO Auto-generated method stub
if (count == 0)
count = 1;
else
count = 2;
android.os.Handler h = new android.os.Handler();
h.postDelayed(new Runnable() {
@Override
public void run() {
if (count == 2) {
this.finish();
// Just Put Your Code for Exit
Log.d("DoubleTap", "Exit");
}
count= 0;
}
}, 500);//You can set double tap interval, currently set half second
// super.onBackPressed();
}
}
Thanks for this, I followed your method but used the delay to reset the counter instead.
ReplyDeleteint backPressed=0;
@Override
public void onBackPressed() {
// This will be called either automatically for you on 2.0
// or later, or by the code above on earlier versions of the
// platform.
if (backPressed == 0) {
Toast.makeText(getApplicationContext(), "Tap again to exit", Toast.LENGTH_SHORT).show();
backPressed=1;
android.os.Handler h = new android.os.Handler();
h.postDelayed(new Runnable() {
@Override
public void run() {
backPressed=0;
}
}, Toast.LENGTH_SHORT);//You can set double tap interval, currently set half second
} else
finish();
}
