Android如何防止特定對話框片段的屏幕旋轉

Question

在我的應用程序中，我有幾個對話框片段。 我想要的是：

當一個特定的對話框片段打開併發生旋轉時，我想阻止該特定片段的屏幕旋轉。

另外，我希望其他片段在屏幕旋轉上正常工作。

下面是對話片段的Java代碼，我想停止屏幕旋轉：

public class DialogDelete extends DialogFragment implements View.OnClickListener { 
 

 
    TextView textViewNaslov, textViewNote; 
 
    ImageView mBtnClose, mBtnReturn, mBtnDelete; 
 
    private RealmResults<Drop> mRealmResolts; 
 
    private Realm mRealm; 
 
    private Calendar calendar;//pravimo objekt kalendara 
 
    private BucketPickerView_Unselected mBucketNoteTimeNonSelected; //ovo nam je drugi bucket pickerview kojeg ne mozemo mjenjati 
 
    private Bundle argumetns; 
 

 

 
    @Override 
 
    public void onCreate(@Nullable Bundle savedInstanceState) { 
 
     super.onCreate(savedInstanceState); 
 
     setStyle(DialogFragment.STYLE_NORMAL, R.style.DialogTheme); //dodajemo temu koju smo napravili preko editora 
 

 
    } 
 

 
    @Nullable 
 
    @Override 
 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
 
     return inflater.inflate(R.layout.dialog_delete, container, false); 
 
    } 
 

 
    @Override 
 
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { 
 
     super.onViewCreated(view, savedInstanceState); 
 

 

 
     mBtnClose = (ImageButton) view.findViewById(R.id.btn_close_note_delete); 
 
     mBtnReturn = (ImageButton) view.findViewById(R.id.dialog_btn_return_delete); 
 
     mBtnDelete = (ImageView) view.findViewById(R.id.dialog_btn_delete); 
 
     textViewNaslov = (TextView) view.findViewById(R.id.dialog_text_naslov_delete); 
 
     textViewNote = (TextView) view.findViewById(R.id.dialog_text_note_delete); 
 
     mBucketNoteTimeNonSelected = (BucketPickerView_Unselected) view.findViewById(R.id.bpv_date_in_note_unselected_deleted); 
 

 

 
     argumetns = getArguments(); // ovo je bundle 
 
     int position = argumetns.getInt("POSITION"); 
 

 
     textViewNaslov.setText(mRealmResolts.get(position).getWhat()); 
 
     textViewNote.setText(mRealmResolts.get(position).getWhat_note()); 
 

 
     long vrijeme = mRealmResolts.get(position).getWhen();//dohvacamo trenutno vrijeme iz realma 
 

 
     calendar = Calendar.getInstance();// dohvacamo objekt kalendar sa masu podataka a medju njima je i DATE, YEAR, MONTH... 
 
     calendar.setTimeInMillis(vrijeme); //postavljamo da je vrijeme ovog kalendar objekta ono koje smo dohvatili iz realma 
 

 
     int date = calendar.get(Calendar.DATE); //dohvacamo iz kalendar bjekta date 
 
     int month = calendar.get(Calendar.MONTH); 
 
     int year = calendar.get(Calendar.YEAR); 
 

 
     mBucketNoteTimeNonSelected.update(date, month, year, 0, 0, 0);//ovo nam je za onaj drugi bucket picker view sto ne mozemo da ga mjenajmo 
 

 

 
     mBtnClose.setOnClickListener(this); 
 
     mBtnReturn.setOnClickListener(this); 
 
     mBtnDelete.setOnClickListener(this); 
 

 
    } 
 

 
    //Pozivamo iz activity prilikom klika i saljemo ove podatke koje koristimo onda ovdje 
 
    public void setChangeDeleteListener(ChangeNoteListener mChangeNoteListener, RealmResults<Drop> realmResults, Realm realm) { 
 
     mRealmResolts = realmResults; 
 
     mRealm = realm; 
 
    } 
 

 
    @Override 
 
    public void onClick(View v) { 
 
     int id = v.getId(); 
 
     int position = argumetns.getInt("POSITION"); 
 

 

 
     switch (id) { 
 
      case R.id.btn_close_note_delete: 
 
       dismiss(); 
 
       break; 
 
      case R.id.dialog_btn_return_delete: 
 
       mRealm.beginTransaction(); 
 
       mRealm.copyToRealm(mRealmResolts.get(position)).setDeleted(false); 
 
       mRealm.commitTransaction(); 
 

 
       Log.d("Petarkaracic", "onClick: Ovo je u dilaog delete "); 
 
       dismiss(); 
 
       break; 
 
      case R.id.dialog_btn_delete: 
 
       mRealm.beginTransaction(); 
 
       mRealmResolts.deleteFromRealm(position); 
 
       mRealm.commitTransaction(); 
 
       Log.d("Petarkaracic", "onClick: Ovo je u dilaog delete "); 
 
       dismiss(); 
 
       break; 
 
     } 
 
    } 
 
}

Answer 1

坐落在DialogFragment類下面的標籤要鎖定屏幕旋轉

@Override public void onResume() { 
    super.onResume(); 
    //lock screen to portrait 
    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 
} 

@Override public void onPause() { 
    super.onPause(); 
    //set rotation to sensor dependent 
    getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR); 
}

在您的片段加入這一行

Settings.System.putInt(getActivity().getContentResolver(), Settings.System.ACCELEROMETER_ROTATION, 0); 
    //change 0 to 1 to enable screen rotation 

你可能需要添加許可

<uses-permission android:name="android.permission.WRITE_SETTINGS" /> 

您可能需要添加運行權限此
