I have an augmented reality app that shows the the camera view and a
GLSurfaceView with a polygon that can be rotated touching the screen.
The main layout of my app is a FrameLayout. The frameLayout contains
the cameraView and the GLSurfaceView. My app also have two buttons on
the screen (zoom in/out) on a RelativeLayout overlaying the
cameraView.
The problem is that the cameraview is overlapping the other two views
(the zoom buttons, and the GLSurfaceView with the polygon), i only can
see the cameraView on the screen. If i remove the cameraview from the
main FrameLayout of my app then i can see the GLSurfaceView and the
zoom buttons without problems.
How can i solve this? i need that the GLSurfaceView overlays the
cameraView and the RelativeLayout with the zoom buttons overlays the
GLSurfaceView...
THis is the code:
public class ARLambo3DSample extends Activity {
private CustomCameraView cv=null;
private ImageView minus;
private ImageView plus;
private MySurfaceView mySurfaceView;
private boolean pressed=false; //algún boton de zoom pulsado
private boolean zoomIn=false; //si zoomIn=true entonces hace zoomIn y
si es false hace zoomOut
private myThread t1; //Hilo que gestiona el zoomIn y el zoomOut
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
FrameLayout fl = new FrameLayout(this.getApplicationContext());
cv = new CustomCameraView(this.getApplicationContext());
RelativeLayout rl= new
RelativeLayout(this.getApplicationContext());
//turn off the window's title bar
requestWindowFeature(Window.FEATURE_NO_TITLE);
//fullscreen
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
fl.addView(cv);
minus= new ImageView(getApplicationContext());
minus.setImageResource(R.drawable.minus2);
rl.addView(minus);
plus= new ImageView(getApplicationContext());
plus.setImageResource(R.drawable.plus2);
rl.addView(plus);
Display display = ((WindowManager)
getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
int w = display.getWidth();
int h = display.getHeight();
RelativeLayout.LayoutParams minusPosition = new
RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
RelativeLayout.LayoutParams plusPosition = new
RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT);
minusPosition.leftMargin = (int)(w*0.77);
minusPosition.topMargin = (int)(h*0.80); //0.66 si no es
fullscreen
minus.setLayoutParams(minusPosition);
plusPosition.leftMargin = (int)(w*0.88);
plusPosition.topMargin = (int)(h*0.80);
plus.setLayoutParams(plusPosition);
mySurfaceView = new MySurfaceView(this);
setContentView(fl);
plus.setClickable(true); //esto es necesario para poder
gestionar
cuando el boton se presiona y se suelta
minus.setClickable(true); //esto es necesario para poder
gestionar
cuando el boton se presiona y se suelta
minus.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
{
switch(event.getAction())
{
case MotionEvent.ACTION_DOWN: //boton
presionado
zoomIn=false;
pressed=true;
break;
case MotionEvent.ACTION_UP: //boton se
suelta
pressed=false;
break;
}
return false;
}
});
plus.setOnTouchListener(new OnTouchListener() {
public boolean onTouch(View v, MotionEvent event)
{
switch(event.getAction())
{
case MotionEvent.ACTION_DOWN: //boton
presionado
zoomIn=true;
pressed=true;
break;
case MotionEvent.ACTION_UP: //boton se
suelta
pressed=false;
break;
}
return false;
}
});
t1= new myThread();
t1.start();
fl.addView(mySurfaceView);
fl.addView(rl);
}
protected void onResume() {
super.onResume();
mySurfaceView.onResume();
}
protected void onPause() {
super.onPause();
mySurfaceView.onPause();
}
}
