捕捉屏幕截图在Android上使用Java code [英] Capture Screen shot on Android using Java code
问题描述
可能重复:
截图Android的
我想捕捉截图编程(不是屏幕截图我的观点),并创建了一个应用程序采取屏幕截图我的看法。
I would like to capture screenshots programatically (not the screen shot of my view) and have created an application to take the screen shot of my view.
我试图捕捉设备的屏幕快照(比如,如果用户opned任何图像文件)通过使用Java code(我想创建服务,并从服务中,我们可以拍照,但我不知道如何实现这一目标)。
I am trying to capture the device screen shot (like if user opned any image file) by using Java code(I thought of creating service and from service we can take picture but I am not sure how to achieve this).
我发现了一些本土code。使用帧缓冲FB0,但我很明白这个,也不知道如何使用它。
I found some native code using frame buffer fb0 but I am very knew to this and no idea how to use it.
推荐答案
下面是一个解决方案,把你的屏幕截图,并把它写入SD卡
Here is a solution to take the screenshot of your screen and write it to the sd card
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( Environment.getExternalStorageDirectory() + "/test.png");
try
{
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, ostream);
ostream.close();
}
catch (Exception e)
{
e.printStackTrace();
}
}
记住要添加
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
您AndroidManifest。
to your AndroidManifest.
