Im a noob at android. Мое приложение продолжает сбой, когда я использую метод AddGroup(), но работает, когда я использую метод Activity AddContentView().Мое приложение вылетает при использовании addView()
Причина, по которой я хочу использовать addView() вместо addContentView(), заключается в том, что я хочу иметь возможность удалять макеты, когда это не необходимо, что невозможно с помощью addContentView().
Код: MainActivity.java
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//CAMERA VIEW
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
surfaceView = (SurfaceView)findViewById(R.id.surfaceview);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.addCallback(this);
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
ViewGroup rootView = (ViewGroup) findViewById(R.layout.activity_main);
LayoutInflater mLayoutInflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
//GRAPHICS VIEW
glSurfaceView = new GLSurfaceView(this);
glSurfaceView.setEGLConfigChooser(8, 8, 8, 8, 16, 0);
glSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
glSurfaceView.setRenderer(new GLRenderer());
//crash
//rootView.addView(glSurfaceView, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
//not crash
addContentView(glSurfaceView, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
glSurfaceView.setZOrderMediaOverlay(true);
//CONTROLS VIEW
View ctrlLayout = mLayoutInflater.inflate(R.layout.activity_controls, rootView);
//crash
//rootView.addView(ctrlLayout, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
//not crash
addContentView(ctrlLayout, new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
ctrlLayout.bringToFront();
textView = (TextView)ctrlLayout.findViewById(R.id.text);
rtTextView = (TextView)ctrlLayout.findViewById(R.id.rt_text);
btnStart = (Button)ctrlLayout.findViewById(R.id.button1);
}

EDIT:
Я изменил свой код, как предложено FD_
ViewGroup rootView = mLayoutInflater.inflate (R.layout.activity_main, null); Теперь, когда я вызываю setContentView (rootView) в конце функции onCreate, он сбой.

Это сделало работу. Мое приложение больше не сбой, но теперь addView() ничего не отображает. Какие-либо предложения? –
И я уже пытался изменить параметры макета glSurfaceView и ctrlView на WRAP_CONTENT, но все еще не работает. –
Если вы используете подход выше (LayoutInflater), вам нужно позвонить setContentView (rootView); в конце onCreate. –
