Мое приложение зависает, когда через addView()

Im noob на android. Мое приложение продолжает сбой всякий раз, когда я использую метод ViewGroup addView (), но работает, когда я использую метод activity addContentView ().

причина, по которой я хочу использовать addView() вместо addContentView (), заключается в том, что я хочу иметь возможность удалять макеты, когда они не нужны, что невозможно с addContentView().

код: В 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);
}

        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/btn_start" />

</RelativeLayout>

EDIT:

Я изменил свой код, как предложил FD_

ViewGroup rootView = mLayoutInflater.надуть (R. layout.activity_main, null); Теперь, когда я вызываю setContentView (rootView) в конце функции onCreate, он аварийно завершает работу.

вот logcat:

нужно позвонить setContentView() прежде чем вы можете использовать findViewById() в своем Activity. Кроме того, findViewById() возвращает представления, включенные в представление содержимого и идентифицированные с помощью id значение передается в качестве аргумента, поэтому передача ресурса макета никогда не будет работать.

другой вариант-раздуть представление самостоятельно, используя LayoutInflater:

LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
ViewGroup rootView  = inflater.inflate(R.layout.main, null);
13

для других, которые в конечном итоге здесь пытаемся отследить эту ошибку, используя пользовательские представления, дважды проверьте, что вы правильно надувать. Следующее изменение решило мои проблемы.

ошибка: 

View view = inflate(getContext(), R.layout.foo, this);
addView(view);

работает: 

View view = inflate(getContext(), R.layout.foo, null);
addView(view);

у меня была такая же проблема при использовании attachToRoot = true

final View submitButton = LayoutInflater.from(this).inflate
            (R.layout.view_button_simple, rootView, true);

мне пришлось изменить его на

final View submitButton = LayoutInflater.from(this).inflate
            (R.layout.view_button_simple, rootView, false);
