Question

我有一个从TabActivity调用的活动（我知道它已被弃用）：

intent2 = new Intent().setClass(this, sin2.class);
spec = tabHost.newTabSpec("second").setIndicator("Second").setContent(intent2);
tabHost.addTab(spec);

这是一个拍摄照片，保存并设置缩略图的活动。它适用于很多设备，但在三星Galaxy Pocket 或 Galaxy Wonder （总是Android 2.x）有时当我启动相机时意图，它永远不会回到onActivityResult()，这意味着：

我拍了照片
我保存
我没有回到onActivityResult()
它允许我拍摄另一张照片

并循环......我再也没有回来，如果按finish()，我会回到当前的活动。

我已经阅读了StackOverflow关于做getParent().startActivityForResult(Intent,RequestCode);之类的内容但是没有用。

这是我拍照的方式：

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mMakePhotoUri = Uri.fromFile(photofile);
i.putExtra(MediaStore.EXTRA_OUTPUT, mMakePhotoUri);
startActivityForResult(i, num);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode==RESULT_OK)
    {
        if (requestCode == 1)
        {
            .............. things I do.
        }
    }
}

提前致谢!!

我的代码：

（photo是一个BitMap）：

        scatta.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View v) {
            photo = null; 
            if(foto1.getDrawable()==null)
                foto(1);
            else if(foto2.getDrawable()==null)
                foto(2);
            else if(foto3.getDrawable()==null)
                foto(3);
            else
                Toast.makeText(sinistri2.this, "Cancella una foto per poter scattare un'altra", Toast.LENGTH_LONG).show();
        }
    });

foto（int）函数：

@SuppressLint("SimpleDateFormat")
public void hacerfoto(int num){
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd_HHmmss");
String n = sdf.format(new Date());
String fotoname = "Immagine-"+ n +".jpg";
File photostorage = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
File photostorage2 = new File(photostorage, "im");
photostorage2.mkdirs();
photofile = new File(photostorage2, fotoname);

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
mMakePhotoUri = Uri.fromFile(photofile);
i.putExtra(MediaStore.EXTRA_OUTPUT, mMakePhotoUri);
startActivityForResult(i, num);
}

我的onActivityResult功能：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    String filename = sacarfoto();

    if (requestCode == 1){

        sacarfoto();


        if(photo != null){
            ruta1 = sacarfoto();
            foto1.setBackgroundColor(Color.parseColor("#00000000"));
            photo = f.resize(photo, filename);
            foto1.setImageBitmap(photo);

            cancellare1.setVisibility(View.VISIBLE);

        }
        else{
            cancellare1.setVisibility(View.GONE);
            foto1.setBackgroundResource(R.drawable.fondoicona);
            Toast.makeText(this, "C'è stato un errore, riprova a scattare la foto", Toast.LENGTH_LONG).show();
        }

        try {
        Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
        File f = new File(ruta1);
        Uri contentUri = Uri.fromFile(f);
        mediaScanIntent.setData(contentUri);
        this.sendBroadcast(mediaScanIntent);
        } catch (Exception e) {

        }
    }
    if (requestCode == 2){
        sacarfoto();
        if(photo != null){
            ruta2 = sacarfoto();
            photo = f.resize(photo, filename);
            foto2.setImageBitmap(photo);
            foto2.setBackgroundColor(Color.parseColor("#00000000"));
            cancellare2.setVisibility(View.VISIBLE);
        }
        else{
            cancellare2.setVisibility(View.GONE);
            foto2.setBackgroundResource(R.drawable.fondoicona);
            Toast.makeText(this, "C'è stato un errore, riprova a scattare la foto", Toast.LENGTH_LONG).show();
        }

        mediaScanIntent.setData(contentUri);
        this.sendBroadcast(mediaScanIntent);
        } catch (Exception e) {

        }
    }
    if (requestCode == 3){
         sacarfoto();

        if(photo != null){
            ruta3 = sacarfoto();
            photo = f.resize(photo, filename);
            foto3.setImageBitmap(photo);

            photo = f.decodeAndResizeFile(new File(selectedImagePath));


        } catch(NullPointerException ex){
            try {
            photo = (Bitmap) data.getExtras().get("data");
            }
            catch (Exception e){

                }
                else if (foto2.getDrawable()==null){
                    photo = f.resize(photo,selectedImagePath);
                    ruta2 = selectedImagePath;
                    foto2.setImageBitmap(photo);
                    foto2.setBackgroundColor(Color.parseColor("#00000000"));
                    cancellare2.setVisibility(View.VISIBLE);
                }
                else if (foto3.getDrawable()==null){
                    photo = f.resize(photo,selectedImagePath);

                    Toast.makeText(sinistri2.this, "Cancella una foto per poter scattare un'altra", Toast.LENGTH_LONG).show();


            }
            else{

                Toast.makeText(this, "Non si è potuto riuscire, riprova scattando una foto o scegliendo una foto dalla gallery.", Toast.LENGTH_LONG).show();
            }
    }
    }

}

函数sacarfoto()给出了一个String但有时可以用于执行一个进程，但是在这个错误中并不重要。

我很确定你认为它永远不会被归还，但事实上它正在返回RESULT_CANCEL。尝试在if(result == RESULT_CANCEL)中添加onActivityResult。也许相机不可能保存图片或类似的东西。

使用Camera Intent拍照永远不会回到onActivityResult（）
