Question

嗨在我的应用程序中，我在android中创建一个应用程序，我必须截取当前活动的屏幕截图并将其保存到SD卡中。

为此我使用一个名为下载的菜单按钮，如果我点击下载我想将当前活动保存到SD卡。

现在我的问题是它保存到SD卡但屏幕截图变成了一半。我想下载整个屏幕并将其保存到sdcard.how下载完整的活动。

任何人都可以帮我解决这个问题。

            } catch (Exception ex) {
                ex.printStackTrace();
            }
            return stream;
        }
    }
}

这是允许我的屏幕截图存储在SD卡上并随后用于您需要的代码，您可以使用以下代码实现：

// image naming and path  to include sd card  appending name you choose for file
String mPath = Environment.getExternalStorageDirectory().toString() + "/" +  ACCUWX.IMAGE_APPEND;   

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

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

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

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

然后，当你需要访问时使用这样的东西： Uri uri = Uri.fromFile（new File（mPath））;

尝试以下代码捕获整个屏幕并保存为位图。：

View v = view.getRootView();
v.setDrawingCacheEnabled(true);
Bitmap b = v.getDrawingCache();
String extr = Environment.getExternalStorageDirectory().toString();
File myPath = new File(extr, "print.jpg");
FileOutputStream fos = null;
try {
    fos = new FileOutputStream(myPath);
    b.compress(Bitmap.CompressFormat.JPEG, 100, fos);
    fos.flush();
    fos.close();
    MediaStore.Images.Media.insertImage( getContentResolver(), b, 
                                         "Screen", "screen");
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

希望这会对你有所帮助。
