Java Examples for android.view.PixelCopy

The following java examples will help you to understand the usage of android.view.PixelCopy. These source code samples are taken from different open source projects.

Example 1

Project: platform_frameworks_base-master File: HardwareCanvasSurfaceViewActivity.java View source code

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FrameLayout content = new FrameLayout(this);
    mSurfaceView = new SurfaceView(this);
    mSurfaceView.getHolder().addCallback(this);
    Button button = new Button(this);
    button.setText("Copy bitmap to /sdcard/surfaceview.png");
    button.setOnClickListener((View v) -> {
        final Bitmap b = Bitmap.createBitmap(mSurfaceView.getWidth(), mSurfaceView.getHeight(), Bitmap.Config.ARGB_8888);
        PixelCopy.request(mSurfaceView, b, (int result) -> {
            if (result != PixelCopy.SUCCESS) {
                Toast.makeText(HardwareCanvasSurfaceViewActivity.this, "Failed to copy", Toast.LENGTH_SHORT).show();
                return;
            }
            try {
                try (FileOutputStream out = new FileOutputStream(Environment.getExternalStorageDirectory() + "/surfaceview.png")) {
                    b.compress(Bitmap.CompressFormat.PNG, 100, out);
                }
            } catch (Exception e) {
            }
        }, mSurfaceView.getHandler());
    });
    LinearLayout layout = new LinearLayout(this);
    layout.setOrientation(LinearLayout.VERTICAL);
    layout.addView(button, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);
    layout.addView(mSurfaceView, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
    content.addView(layout, new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT));
    setContentView(content);
}
