对于那些想要捕获GLSurfaceView的人，getDrawingCache或绘制到画布方法将不起作用。

在帧呈现之后，您必须读取OpenGL帧缓冲区的内容。这里有一个很好的答案

对于整页滚动截图

如果你想要捕捉一个完整的视图截图(其中包含一个滚动视图左右)，那么在这个库中进行检查

https://github.com/peter1492/LongScreenshot

你所要做的就是导入Gradel，并创建一个bigscreen的对象

长截图=新BigScreenshot(这个，x, y);

当自动滚动屏幕视图组并在最后组装在一起时，将接收回调的屏幕截图位图。

get截图(Bitmap) {}

哪些可以保存到画廊或任何必要的用途，他们之后

仅限系统应用!

Process process;
process = Runtime.getRuntime().exec("screencap -p " + outputPath);
process.waitFor();

注意:系统应用不需要执行“su”命令执行该命令。

如果你想从片段中截取截图，请遵循以下步骤:

Override onCreateView(): @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment View view = inflater.inflate(R.layout.fragment_one, container, false); mView = view; } Logic for taking screenshot: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { View view = mView.findViewById(R.id.scrollView1); shareScreenShotM(view, (NestedScrollView) view); } method shareScreenShotM)(): public void shareScreenShotM(View view, NestedScrollView scrollView){ bm = takeScreenShot(view,scrollView); //method to take screenshot File file = savePic(bm); // method to save screenshot in phone. } method takeScreenShot(): public Bitmap takeScreenShot(View u, NestedScrollView z){ u.setDrawingCacheEnabled(true); int totalHeight = z.getChildAt(0).getHeight(); int totalWidth = z.getChildAt(0).getWidth(); Log.d("yoheight",""+ totalHeight); Log.d("yowidth",""+ totalWidth); u.layout(0, 0, totalWidth, totalHeight); u.buildDrawingCache(); Bitmap b = Bitmap.createBitmap(u.getDrawingCache()); u.setDrawingCacheEnabled(false); u.destroyDrawingCache(); return b; } method savePic(): public static File savePic(Bitmap bm){ ByteArrayOutputStream bytes = new ByteArrayOutputStream(); bm.compress(Bitmap.CompressFormat.JPEG, 100, bytes); File sdCardDirectory = new File(Environment.getExternalStorageDirectory() + "/Foldername"); if (!sdCardDirectory.exists()) { sdCardDirectory.mkdirs(); } // File file = new File(dir, fileName); try { file = new File(sdCardDirectory, Calendar.getInstance() .getTimeInMillis() + ".jpg"); file.createNewFile(); new FileOutputStream(file).write(bytes.toByteArray()); Log.d("Fabsolute", "File Saved::--->" + file.getAbsolutePath()); Log.d("Sabsolute", "File Saved::--->" + sdCardDirectory.getAbsolutePath()); } catch (IOException e) { e.printStackTrace(); } return file; }

对于activity，您可以简单地使用View v1 = getWindow().getDecorView().getRootView();而不是mView

注:仅适用于root phone

编程方式:adb shell /system/bin/screencap -p /sdcard/img.png

Process sh = Runtime.getRuntime().exec("su", null,null);
OutputStream os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));
os.flush();
os.close();
sh.waitFor();    

然后将img.png读取为位图，并按照您的意愿使用。

调用这个方法，传入你想要屏幕截图的最外层ViewGroup:

public Bitmap screenShot(View view) {
    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),
            view.getHeight(), Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    view.draw(canvas);
    return bitmap;
}
