从Android 11 (API级别30)，你可以用辅助服务截屏:

takeScreenshot -截取指定显示的屏幕截图，并通过AccessibilityService.ScreenshotResult返回。

参数视图是根布局对象。

public static Bitmap screenShot(View view) {
                    Bitmap bitmap = null;
                    if (view.getWidth() > 0 && view.getHeight() > 0) {
                        bitmap = Bitmap.createBitmap(view.getWidth(),
                                view.getHeight(), Bitmap.Config.ARGB_8888);
                        Canvas canvas = new Canvas(bitmap);
                        view.draw(canvas);
                    }
                    return bitmap;
                }

您可以尝试以下库: http://code.google.com/p/android-screenshot-library/ Android截图库(ASL)允许以编程方式从Android设备捕获屏幕截图，而不需要具有root访问权限。相反，ASL利用了在后台运行的本地服务，每次设备启动时通过Android调试桥(ADB)启动。

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

这个问题的大多数答案使用Canvas绘图方法或绘图缓存方法。然而，View.setDrawingCache()方法在API 28中已弃用。目前，用于制作截图的推荐API是API 24提供的PixelCopy类(但接受Window参数的方法可从API 26 == Android 8.0 Oreo获得)。下面是一个检索位图的示例Kotlin代码:

@RequiresApi(Build.VERSION_CODES.O)
fun saveScreenshot(view: View) {
    val window = (view.context as Activity).window
    if (window != null) {
        val bitmap = Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)
        val locationOfViewInWindow = IntArray(2)
        view.getLocationInWindow(locationOfViewInWindow)
        try {
            PixelCopy.request(window, Rect(locationOfViewInWindow[0], locationOfViewInWindow[1], locationOfViewInWindow[0] + view.width, locationOfViewInWindow[1] + view.height), bitmap, { copyResult ->
                if (copyResult == PixelCopy.SUCCESS) {
                    saveBitmap(bitmap)
                }
                // possible to handle other result codes ...
            }, Handler())
        } catch (e: IllegalArgumentException) {
            // PixelCopy may throw IllegalArgumentException, make sure to handle it
        }
    }
}

只是扩展塔拉洛卡的答案。您必须添加以下行才能使其工作。我已将映像名称设置为静态。请确保您使用taraloca的时间戳变量，以防您需要动态图像名称。

    // Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
        Manifest.permission.READ_EXTERNAL_STORAGE,
        Manifest.permission.WRITE_EXTERNAL_STORAGE
};

private void verifyStoragePermissions() {
    // Check if we have write permission
    int permission = ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        // We don't have permission so prompt the user
        ActivityCompat.requestPermissions(this, PERMISSIONS_STORAGE, REQUEST_EXTERNAL_STORAGE);
    }else{
        takeScreenshot();
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        if (requestCode == REQUEST_EXTERNAL_STORAGE) {
            takeScreenshot();
        }
    }
}

在AndroidManifest.xml文件中，以下条目是必须的:

< uses-permission android: name = " android.permission。READ_EXTERNAL_STORAGE " / > < uses-permission android: name = " android.permission。WRITE_EXTERNAL_STORAGE " / >
