通过code的Andr​​oid抓图 [英] Android take screenshot via code

问题描述

这应该不会太艰难的问题。我想利用我的布局（视图）的屏幕截图，并通过手机短信发送的能力。有人可以走我虽然步骤？

This shouldn't be too tough of a question. I want the ability to take a screenshot of my layout (view) and send it via sms. Can someone walk me though the steps?

谢谢！

编辑： 它没有成为一个屏幕截图我想，只要你将我们从一个视图以某种方式让所有的渲染像素。

It doesn't have to be a 'screenshot' I guess, just as long as we can get all of the rendered pixels from a view somehow.

推荐答案

围绕网络我发现code一些片段，我能得到协同工作。

Around the web I found some snippets of code that I was able to get working together.

下面是一个解决方案，效果很好：

Here is a solution that works well:

设置根布局：

View content = findViewById(R.id.layoutroot);
content.setDrawingCacheEnabled(true);

函数来获取渲染视图：

Function to get the rendered view:

private void getScreen()
{
    View content = findViewById(R.id.layoutroot);
    Bitmap bitmap = content.getDrawingCache();
    File file = new File("/sdcard/test.png");
    try 
    {
        file.createNewFile();
        FileOutputStream ostream = new FileOutputStream(file);
        bitmap.compress(CompressFormat.PNG, 100, ostream);
        ostream.close();
    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }
}
