如何以编程方式获取/合并谷歌地图v2和xml布局的屏幕截图？

Question

我正在使用这个答案的代码来截取Google Map v2, 它给出了输出:

哪个可以拍摄Map的屏幕截图

使用以下代码,我可以使用黑色地图屏幕的布局屏幕截图,如下面的代码地图将在ScreenShot中黑色

String mPath = Environment.getExternalStorageDirectory().toString()
                + "/" + "myTestScr" + System.currentTimeMillis() + ".jpeg";
Bitmap bitmap;
        View v1 = (View) findViewById(R.id.rootviewtest);
        v1.setDrawingCacheEnabled(true);
        bitmap = Bitmap.createBitmap(v1.getDrawingCache());
        v1.setDrawingCacheEnabled(false);

        OutputStream fout = null;
        File imageFile = new File(mPath);

        try {
            fout = new FileOutputStream(imageFile);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
            fout.flush();
            fout.close();

        } catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

以上代码的输出:

我真正需要的是:

所以,现在我的问题是如何在第3屏幕中获得输出programmatically？

帮我合并两个(1和2)屏幕拍摄一个屏幕截图programmatically？

或者programmatically在拍摄(1和2)屏幕截图后合并两个图像的任何其他替代方案？

调用以下方法以使用地图截取屏幕截图:

public void captureMapScreen() {
        SnapshotReadyCallback callback = new SnapshotReadyCallback() {

            @Override
            public void onSnapshotReady(Bitmap snapshot) {
                try {
                    mView.setDrawingCacheEnabled(true);
                    Bitmap backBitmap = mView.getDrawingCache();
                    Bitmap bmOverlay = Bitmap.createBitmap(
                            backBitmap.getWidth(), backBitmap.getHeight(),
                            backBitmap.getConfig());
                    Canvas canvas = new Canvas(bmOverlay);
                    canvas.drawBitmap(snapshot, new Matrix(), null);
                    canvas.drawBitmap(backBitmap, 0, 0, null);
                    FileOutputStream out = new FileOutputStream(
                            Environment.getExternalStorageDirectory()
                                    + "/MapScreenShot"
                                    + System.currentTimeMillis() + ".png");

                    bmOverlay.compress(Bitmap.CompressFormat.PNG, 90, out);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        };

        mMap.snapshot(callback);

    }

mview是您的布局的根视图,mMap是您的地图片段.

确保您拥有最新的Google Play ServicesAPI.

mView.setDrawingCacheEnabled(true);
Bitmap backBitmap = mView.getDrawingCache();
Bitmap bmOverlay = Bitmap.createBitmap(
backBitmap.getWidth(), backBitmap.getHeight(),
backBitmap.getConfig());
Canvas canvas = new Canvas(bmOverlay);
canvas.drawBitmap(snapshot, new Matrix(), null);
canvas.drawBitmap(backBitmap, 0, 0, null);

snapshot.compress(Bitmap.CompressFormat.PNG, 90, out);如果您只想要地图的屏幕截图,请跳过这些行并使用.
