推荐答案

您可以通过重写做到这一点的onPause 中的onPause方法活动和方法清除所有的EditText值：

you can do this by overriding onPause method of Activity and in onPause method clear all EditText Value as:

@Override
 protected void onPause(){
        super.onPause();

         // Clear all value here
        editTextone.setText("");
        editTexttwo.setText("");
    }
