Android call onClick method without Clicking

问题:

I want to use existing onClick method to make my program simpler. It consists of onClick method and other method:

@Override public void onClick(View v) {   switch(v.getId()){   case R.id.button1:     ....     break;   } }  void foo(){   ....   onClick(????); } 

Is there any way to make it do the same behaviour like when i click it on the phone?

回答1:

you can use View.performClick()

reference

回答2:

performClick() will play a sound just like if the user clicked on that view, therefore in most cases it's better to use callOnClick(), which will call the OnClickListener without playing any click sound. (Available since API level 15)

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) myView.callOnClick(); //won't play sound else myView.performClick(); //will play sound
