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)
        {
          e.printStackTrace();
        }
    }

调用方法：

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