無法使用Theme.Dialog啓動活動

我不知道如何處理這個問題，我想我已到處搜索。但是這個問題只是神祕的。我有一個名爲EditdataActivity無法使用Theme.Dialog啓動活動

public class EditdataActivity extends ActionBarActivity{ 
    logclass clogs = new logclass(); 
    EditText edt_ln; 
    EditText edt_lat; 
    EditText edt_long; 
    Button btn_cancel; 
    Button btn_save; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_dataedit); 
     clogs =(logclass) getIntent().getSerializableExtra("MyClass"); 
     edt_ln = (EditText) findViewById(R.id.edt_Ln); 
     edt_lat = (EditText) findViewById(R.id.edt_lat); 
     edt_long = (EditText) findViewById(R.id.det_long); 
     btn_cancel = (Button) findViewById(R.id.cancel_btn); 
     btn_save = (Button) findViewById(R.id.btn_save); 

     edt_ln.setText(clogs.getname()); 
     edt_lat.setText(clogs.getlatloc()+""); 
     edt_long.setText(clogs.getlongloc()+""); 

     OnClickListener savelistener = new OnClickListener() {   
      @Override 
      public void onClick(View v) { 
       //notifpopup("Save changes?"); 
      } 
     }; 
     btn_save.setOnClickListener(savelistener);  

     OnClickListener cancellistener = new OnClickListener() {    
      @Override 
      public void onClick(View v) { 
       Intent intent1 = new Intent(EditdataActivity.this, AdddataclassActivity.class); 
       intent1.putExtra("MyClass", clogs); 
       intent1.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
       startActivity(intent1); 
       overridePendingTransition (R.anim.open_main, R.anim.close_next); 
      } 
     }; 
     btn_cancel.setOnClickListener(cancellistener); 

    } 

    void notifpopup(String notif){ 
     AlertDialog.Builder alert = new AlertDialog.Builder(this); 
     alert.setTitle(notif); 
     alert.setPositiveButton("YES", new DialogInterface.OnClickListener() { 
      public void onClick(DialogInterface dialog, int whichButton) { 
       clogs.setname(edt_ln.getText().toString()); 
       double lat = Double.parseDouble(edt_lat.getText().toString()); 
       double longl = Double.parseDouble(edt_long.getText().toString()); 
       clogs.setlatloc(lat); 
       clogs.setlongloc(longl); 
      } 
     }); 

     alert.setNegativeButton("Cancel", 
       new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int whichButton) { 

        } 
      }); 

      alert.show(); 
    } 
}

的活動，這是從這個活動

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     ........ 
     clogs =(logclass) getIntent().getSerializableExtra("MyClass"); 
     ........ 

      Button edit_data = (Button) findViewById(R.id.btn_addattrbdel); 
      OnClickListener editlistener = new OnClickListener() {   
       @Override 
       public void onClick(View v) { 
        gotoeditview(); 
       } 
      }; 
      edit_data.setOnClickListener(editlistener); 
    } 

    void gotoeditview(){ 
     Intent intentl = new Intent(this,EditdataActivity.class); 
     intentl.putExtra("MyClass", clogs); 
     intentl.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
     startActivity(intentl); 
     overridePendingTransition (R.anim.appear, R.anim.disappear); 
    }

稱爲然而，當我執行它，如在logcat的beloc

發生錯誤..但正如我已經讀過一些建議的解決方案，我將我的EditDataActivity更改爲Acitvity ..它沒有任何錯誤..但它只顯示此..

我有其他活動而這正是像這樣在我的項目。但他們都工作正常，我試過..重新啓動我的Eclipse IDE ..但它沒有工作..請幫助，也許我只是忘了一些東西。感謝..這裏是我的項目的清單文件..

對不起，我長的帖子...

是什麼THR在ActionBarActivityDelegate.java:110，並張貼烏爾ActionBarActivityDelegate.java文件太多。 – 2014-10-17 09:25:06

IllegalStateException，在VM未處於正確狀態時嘗試執行操作時引發。 – 2014-10-17 09:28:20

如果您想創建自己的自定義對話框，請創建延伸DialogFragment而不是創建活動的類。它很容易使用，您不必在清單中聲明它們。

使用這樣的：

public class EditDataDialog extends DialogFragment { 

    // Properties here 
    ..... 

    @Override 
    public View onCreateView(LayoutInflater inflater, 
      ViewGroup container, Bundle savedInstanceState) 
    { 
     View view = inflater.inflate(R.layout.activity_dataedit, container, false); 

     // Properties init here 
     ..... 

     return view; 
    } 
}

然後，在您的主要活動，稱之爲：

// Show the "edit data" dialog 
FragmentManager fm = getSupportFragmentManager(); 
EditDataDialog editDataDialog = new EditDataDialog(); 
editDataDialog.show(fm, "edit_data_dialog");

我想我寧願使用這種方法..比使用其他活動..它更容易處理..謝謝... – ErenRavenHeart 2014-10-17 09:58:04

好，很高興能有用:) – 2014-10-17 10:16:57

如果你想使用ActionBarActivity，它的主題必須是一個Theme.AppCompat主題（或後代）。

如果你想使用Theme.Dialog主題，你的活動不應該延伸ActionBarActivity。
