使用手机摄像头,捕获图像活动后不会返回特定活动

Question

我正在使用手机的相机并使用android.provider.MediaStore.ACTION_IMAGE_CAPTURE从我的应用程序中捕获图像.

单击捕获按钮后,它会显示保存或丢弃.单击保存按钮,它将返回相机而不是应用程序.并且图像保存在gallary中而不是我声明的输出文件中.

以下是我的代码

    @Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    Intent in=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    startActivityForResult(in, 0);

}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (resultCode==RESULT_OK) {
    Bitmap bm=(Bitmap) data.getExtras().get("data");
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    bm.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

    //you can create a new file name "test.jpg" in sdcard folder.
    File f = new File(Environment.getExternalStorageDirectory()
                            + File.separator + "player1.jpg");
    try {
        f.createNewFile();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    //write the bytes in file
    FileOutputStream fo = null;
    try {
        fo = new FileOutputStream(f);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    try {
        fo.write(bytes.toByteArray());
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }finally{
        Intent pic=new Intent(pic1.this, GameMenu.class);
        startActivity(pic);
        finish();
    }
}
else {
    Toast.makeText(getApplicationContext(), "Canceled", Toast.LENGTH_LONG).show();
    Intent pic=new Intent(pic1.this, Menu.class);
    startActivity(pic);
    finish();
}

请提出是否有任何解决方案..提前致谢...

编辑1:我已经在三星galaxy y duos(android 2.3.6)上检查了这段代码,但它无法正常工作.并且在galaxy pop(2.2.1)和HTC野火(2.3.5)上检查相同,它的工作完美.

使用下面的意图来捕获图像，getTempFile()是您提到的存储路径

Intent photoPickerIntent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                       photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempFile());

                       photoPickerIntent.putExtra("outputFormat",Bitmap.CompressFormat.JPEG.toString());
                       photoPickerIntent.putExtra("return-data", true);
                       startActivityForResult(photoPickerIntent,TAKE_PICTURE);

获取临时文件：

private Uri getTempFile() {


        File root = new File(Environment.getExternalStorageDirectory(), "Directory");
        if (!root.exists()) {
            root.mkdirs();
        }
             File file;

             file = new File(root,filename+".jpeg" );

             muri = Uri.fromFile(file);
             photopath=muri.getPath();

              Log.e("getpath",muri.getPath());
              return muri;

           }
