我已经是从所谓的活动TabActivity（我知道这是不建议使用）为：带摄像头的意图拍照永远不会回到onActivityResult（）
intent2 = new Intent().setClass(this, sin2.class);
spec = tabHost.newTabSpec("second").setIndicator("Second").setContent(intent2);
tabHost.addTab(spec);
这是拍摄照片的活动，将它们保存并设置缩略图。它完美的作品在大量的设备，但三星Galaxy掌上或银河奇迹（总的Android 2.X）有时当我启动相机意图，它永远不会回到onActivityResult()，这意味着：
- 我拍照
- 我保存它
- 我不回去
onActivityResult() - 它让我再拍一张照片
和循环...我永远不会回来，如果我按finish()，我回到我目前的活动。
我读过StackOverflow关于做像getParent().startActivityForResult(Intent,RequestCode);这样的东西，但不起作用。
这是我把我的照片：提前
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.
}
}
}
谢谢！
我的代码：
上的onCreate（photo是位图）：
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();
}
});
照片（INT）功能：
@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){

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 {

函数sacarfoto()给出了一个String，但有时候会用于执行一个进程，但这个错误并不重要。
“num”的值是什么？ –
我有很多'if（requestCode == someNum）'，我处理它...它在一些设备上正常工作，例如我的。 num可能是1,2或3 –
