我想确认设置属性

android:filterTouchesWhenObscured ="true"

会阻止这种情况在设备间发生，因为我打算制作一个安全的应用程序.

推荐答案

public class MyActivity extends Activity {
    protected void onCreate(Bundle bundle) {
        super.onCreate(bundle);
        final Button myButton = (Button)findViewById(R.id.button_id);
        myButton.setFilterTouchesWhenObscured(true);
        myButton.setOnClickListener(new View.OnClickListener() {
            // Perform action on click
            public void onClick(View v) {

            }
        }
    }
}
