我已經是從所謂的活動TabActivity
(我知道這是不建議使用)爲:帶攝像頭的意圖拍照永遠不會回到onActivityResult()
intent2 = new Intent().setClass(this, sin2.class);
spec = tabHost.newTabSpec("second").setIndicator("Second").setContent(intent2);
tabHost.addTab(spec);
這是拍攝照片的活動,將它們保存並設置縮略圖。它完美的作品在大量的設備,但三星Galaxy掌上或銀河奇蹟(總的Android 2.X)有時當我啓動相機意圖,它永遠不會回到onActivityResult()
,這意味着:
- 我拍照
- 我保存它
- 我不回去
onActivityResult()
- 它讓我再拍一張照片
和循環...我永遠不會回來,如果我按finish()
,我回到我目前的活動。
我讀過StackOverflow關於做像getParent().startActivityForResult(Intent,RequestCode);
這樣的東西,但不起作用。
這是我把我的照片: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.
}
}
}
謝謝!
我的代碼:
上的onCreate(photo
是位圖):
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);

函數sacarfoto()
給出了一個String,但有時候會用於執行一個進程,但這個錯誤並不重要。
「num」的值是什麼? –
我有很多'if(requestCode == someNum)',我處理它...它在一些設備上正常工作,例如我的。 num可能是1,2或3 –
