谷歌已经完成了这项功能要求。请看

原始问题

使用旧版本的谷歌地图Android API,我能够捕获谷歌地图的屏幕截图,并通过社交媒体共享。我使用以下代码捕获屏幕截图并将图像保存到文件中,效果非常好:

public String captureScreen()
{
    String storageState = Environment.getExternalStorageState();
    Log.d("StorageState", "Storage state is: " + storageState);

    // image naming and path  to include sd card  appending name you choose for file
    String mPath = this.getFilesDir().getAbsolutePath();

    // create bitmap screen capture
    Bitmap bitmap;
    View v1 = this.mapView.getRootView();
    v1.setDrawingCacheEnabled(true);
    bitmap = Bitmap.createBitmap(v1.getDrawingCache());
    v1.setDrawingCacheEnabled(false);

    OutputStream fout = null;

    String filePath = System.currentTimeMillis() + ".jpeg";

    try 
    {
        fout = openFileOutput(filePath,
                MODE_WORLD_READABLE);

        // Write the string to the file
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
        fout.flush();
        fout.close();
    } 
    catch (FileNotFoundException e) 
    {
        // TODO Auto-generated catch block
        Log.d("ImageCapture", "FileNotFoundException");
        Log.d("ImageCapture", e.getMessage());
        filePath = "";
    } 
    catch (IOException e) 
    {
        // TODO Auto-generated catch block
        Log.d("ImageCapture", "IOException");
        Log.d("ImageCapture", e.getMessage());
        filePath = "";
    }

    return filePath;
}
但是,api V2使用的新GoogleMap对象不像MapView那样具有“getRootView()”方法

我试着这样做:

    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.basicMap);

    View v1 = mapFragment.getView();
但我得到的屏幕截图没有任何地图内容,如下所示:

有人知道如何拍摄新的谷歌地图Android API V2的截图吗

更新

我还尝试通过以下方式获取rootView:

View v1 = getWindow().getDecorView().getRootView();
这会产生一个屏幕截图,其中包括屏幕顶部的操作栏,但地图仍然是空白的,就像我附加的屏幕截图一样

更新


一个功能请求已经提交给谷歌。如果这是您希望google在将来添加的内容,请启动功能请求:

编辑:此答案不再有效-google Maps Android API V2上的屏幕截图功能请求已完成。看

原始接受答案


由于新的Android API v2地图是使用OpenGL显示的,因此不可能创建屏幕截图。

Eclipse DDMS可以捕获屏幕,即使它是google map v2


如果您有“root”,请尝试调用/system/bin/screencap或/system/bin/screenshot。我从更新中了解到,Google添加了一个快照方法**!:

已经完成了对Android Google Map API V2 OpenGL层截屏方法的功能请求

要获取屏幕截图,只需实现以下界面:

public abstract void onSnapshotReady (Bitmap snapshot)
并致电:

公共最终作废快照(GoogleMap.SnapshotReadyCallback回调)


该示例截图显示了标准的“图像共享”选项:

图像捕获完成后,它将触发标准的“共享图像”对话框,以便用户选择如何共享图像:

public void openShareImageDialog(String filePath) 
{
File file = this.getFileStreamPath(filePath);

if(!filePath.equals(""))
{
    final ContentValues values = new ContentValues(2);
    values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
    values.put(MediaStore.Images.Media.DATA, file.getAbsolutePath());
    final Uri contentUriFile = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);

    final Intent intent = new Intent(android.content.Intent.ACTION_SEND);
    intent.setType("image/jpeg");
    intent.putExtra(android.content.Intent.EXTRA_STREAM, contentUriFile);
    startActivity(Intent.createChooser(intent, "Share Image"));
}
else
{
            //This is a custom class I use to show dialogs...simply replace this with whatever you want to show an error message, Toast, etc.
    DialogUtilities.showOkDialogWithText(this, R.string.shareImageFailed);
}
}

文档如下

以下是用示例捕获Google Map V2屏幕截图的步骤

第1步。打开
Android Sdk管理器(窗口>Android Sdk管理器)
然后
展开附加功能
now
更新/安装Google Play Services至第10版
如果已安装
则忽略此步骤

在这里读笔记

第2步。
重新启动Eclipse

第3步。
导入com.google.android.gms.maps.GoogleMap.SnapshotReadyCallback

第4步。如下图所示,制作捕捉/存储地图屏幕/图像的方法

public void CaptureMapScreen() 
{
SnapshotReadyCallback callback = new SnapshotReadyCallback() {
            Bitmap bitmap;

            @Override
            public void onSnapshotReady(Bitmap snapshot) {
                // TODO Auto-generated method stub
                bitmap = snapshot;
                try {
                    FileOutputStream out = new FileOutputStream("/mnt/sdcard/"
                        + "MyMapScreen" + System.currentTimeMillis()
                        + ".png");

                    // above "/mnt ..... png" => is a storage path (where image will be stored) + name of image you can customize as per your Requirement

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

        myMap.snapshot(callback);

        // myMap is object of GoogleMap +> GoogleMap myMap;
        // which is initialized in onCreate() => 
        // myMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map_pass_home_call)).getMap();
}
第5步。现在调用此
CaptureMapScreen()
方法来捕获图像

在我的例子中,
在onCreate()中单击按钮调用此方法,
工作正常

如:

Button btnCap = (Button) findViewById(R.id.btnTakeScreenshot);
    btnCap.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            try {
                CaptureMapScreen();
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }

        }
    });
gmap.setOnMapLoadedCallback(mapLoadedCallback);
final SnapshotReadyCallback snapReadyCallback = new SnapshotReadyCallback() {
        Bitmap bitmap;
        @Override
        public void onSnapshotReady(Bitmap snapshot) {
            bitmap = snapshot;

            try {

                //do something with your snapshot

                imageview.setImageBitmap(bitmap);

            } catch (Exception e) {
                e.printStackTrace();
            }


        }
    };

GoogleMap.OnMapLoadedCallback mapLoadedCallback = new GoogleMap.OnMapLoadedCallback() {
        @Override
        public void onMapLoaded() {
            gmap.snapshot(snapReadyCallback);
        }
};

检查Doc和

,因为投票最多的答案不适用于地图片段顶部的多段线和其他覆盖(我一直在寻找),所以我想分享这个解决方案

public void captureScreen()
        {
            GoogleMap.SnapshotReadyCallback callback = new GoogleMap.SnapshotReadyCallback()
            {


                @Override
                public void onSnapshotReady(Bitmap snapshot) {
                    try {
                        getWindow().getDecorView().findViewById(android.R.id.content).setDrawingCacheEnabled(true);
                        Bitmap backBitmap = getWindow().getDecorView().findViewById(android.R.id.content).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);

                        OutputStream fout = null;

                        String filePath = System.currentTimeMillis() + ".jpeg";

                        try
                        {
                            fout = openFileOutput(filePath,
                                    MODE_WORLD_READABLE);

                            // Write the string to the file
                            bmOverlay.compress(Bitmap.CompressFormat.JPEG, 90, fout);
                            fout.flush();
                            fout.close();
                        }
                        catch (FileNotFoundException e)
                        {
                            // TODO Auto-generated catch block
                            Log.d("ImageCapture", "FileNotFoundException");
                            Log.d("ImageCapture", e.getMessage());
                            filePath = "";
                        }
                        catch (IOException e)
                        {
                            // TODO Auto-generated catch block
                            Log.d("ImageCapture", "IOException");
                            Log.d("ImageCapture", e.getMessage());
                            filePath = "";
                        }

                        openShareImageDialog(filePath);


                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            };

           ;


            map.snapshot(callback);
        }
