Android截图 截取ContentView 截取指定的View并且保存

释放双眼,带上耳机,听听看~!

截取DecorView

getWindow().getDecorView().setDrawingCacheEnabled(true);
        try {
            File myCaptureFile = new File("/mnt/sdcard/"
                    + System.currentTimeMillis() + ".jpg");
            BufferedOutputStream bos = new BufferedOutputStream(
                    new FileOutputStream(myCaptureFile));
            getWindow().getDecorView().getDrawingCache()
                    .compress(Bitmap.CompressFormat.JPEG, 80, bos);
            bos.flush();
            bos.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        getWindow().getDecorView().setDrawingCacheEnabled(false);

截取指定的View

view.setDrawingCacheEnabled(true);
        try {
            File myCaptureFile = new File("/mnt/sdcard/"
                    + System.currentTimeMillis() + ".jpg");
            BufferedOutputStream bos = new BufferedOutputStream(
                    new FileOutputStream(myCaptureFile));
            view.getDrawingCache()
                    .compress(Bitmap.CompressFormat.JPEG, 80, bos);
            bos.flush();
            bos.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        view().setDrawingCacheEnabled(false);

截取不包括状态栏的部分

/**
     * 页面返回动画
     */
    private void gobackAnimation(){
        getWindow().getDecorView().setDrawingCacheEnabled(true);
        Bitmap bm = getWindow().getDecorView().getDrawingCache();
        Rect rect = new Rect();
        getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);
        final Bitmap bitmap = Bitmap.createBitmap(bm, 0, rect.top, Device.getScreenWidth(), Device.getScreenHeight() - rect.top);;
        bm.recycle();
        final ImageView imageView = new ImageView(ActivityOnlineAndUser.this);
        imageView.setScaleType(ScaleType.FIT_XY);
        imageView.setImageBitmap(bitmap);
        getWindow().addContentView(imageView, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
        Animation anim = AnimationUtils.loadAnimation(ActivityOnlineAndUser.this, R.anim.push_right_out);
        anim.setAnimationListener(new AnimationListener() {
            
            @Override
            public void onAnimationStart(Animation animation) {
                
            }
            
            @Override
            public void onAnimationRepeat(Animation animation) {
                
            }
            
            @Override
            public void onAnimationEnd(Animation animation) {
                // 回收资源
                imageView.setImageBitmap(null);
                bitmap.recycle();
                ((ViewGroup)imageView.getParent()).removeView(imageView);
                // 设置成False,否则会很浪费性能
                getWindow().getDecorView().setDrawingCacheEnabled(false);
            }
        });
        imageView.startAnimation(anim);
    }
