Example 83 with SurfaceView

use of android.view.SurfaceView in project BarcodeEye by BarcodeEye.

the class CaptureActivity method onResume.

@Override
protected void onResume() {
    super.onResume();
    // CameraManager must be initialized here, not in onCreate(). This is necessary because we don't
    // want to open the camera driver and measure the screen size if we're going to show the help on
    // first launch. That led to bugs where the scanning rectangle was the wrong size and partially
    // off screen.
    mCameraManager = new CameraManager(getApplication());
    mViewfinderView.setCameraManager(mCameraManager);
    mHandler = null;
    SurfaceView surfaceView = (SurfaceView) findViewById(R.id.preview_view);
    SurfaceHolder surfaceHolder = surfaceView.getHolder();
    if (mHasSurface) {
        // The activity was paused but not stopped, so the surface still exists. Therefore
        // surfaceCreated() won't be called, so init the camera here.
        initCamera(surfaceHolder);
    } else {
        // Install the callback and wait for surfaceCreated() to init the camera.
        surfaceHolder.addCallback(this);
