Android 实现简单截屏并保存为文件

直接上代码：

    /**     * 截屏     * @param v视图     * @param filePath  保存路径     */    private void getScreenHot(View v, String filePath)    {                try        {        Bitmap bitmap = Bitmap.createBitmap(v.getWidth(), v.getHeight(), Config.ARGB_8888);        Canvas canvas = new Canvas();        canvas.setBitmap(bitmap);        v.draw(canvas);        try        {        FileOutputStream fos = new FileOutputStream(filePath);        bitmap.compress(CompressFormat.PNG, 100, fos);        }        catch (FileNotFoundException e)        {        throw new InvalidParameterException();        }        }        catch (Exception e)        {          Log.i("截屏", "内存不足！");          e.printStackTrace();        }    }

调用方法：

getScreenHot((View) getWindow().getDecorView(), "/sdcard/test1.png");
