an xml layout will be displayed in the form of dialog

In service , the effect of this dialog is no problem .

But if it is in intentservice , the same as the start dialog code, all run , no error, just do not show this dialog box , which is why?
Great God seeking answers ah ! ! ! !

intentservice is a subclass of service , which in addition to the message handling both bit different, why this difference so big? ? ? ? Jia ! ! !

intentservice in the part of the code :


protected void onHandleIntent (Intent intent) {
_DownloadApkService.requestService ();
}

then requestService () in a dialog box will open to display the dialog code as follows:

	public void showUpdateDialog(){
  		View v = View.inflate(context, R.layout.update, null);
  		AlertDialog.Builder builder = new AlertDialog.Builder(context);
  		builder.setTitle("yyyyyyyy");
  		String new_version_desc = getSharePreferences(HybridGlobalDefination._New_Version_Desc, "New Version, download now?");
  		builder.setMessage(new_version_desc);
  		builder.setView(v);
  		tDialog = builder.create();
  		tDialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
  		tDialog.show();
  		WindowManager.LayoutParams lp = tDialog.getWindow().getAttributes();
  		WindowManager wm = (WindowManager)context.getSystemService(Context.WINDOW_SERVICE);
  		Display display = wm.getDefaultDisplay();
  		if(display.getHeight() > display.getWidth()){
  			lp.width = (int)(display.getWidth() * 1.0);
  		}
  		else{
  			lp.width = (int)(display.getWidth() * 0.5);
  		}
  		tDialog.getWindow().setAttributes(lp);
  		Button bt1 = (Button)tDialog.getWindow().findViewById(R.id.button2);
  		bt1.setOnClickListener(new Button.OnClickListener(){
  			public void onClick(View v) {
  				downloadStatusBar();
  				tDialog.dismiss();	
  				
  			}			
  		});
  		Button bt2 = (Button)tDialog.getWindow().findViewById(R.id.button1);
  		bt2.setOnClickListener(new Button.OnClickListener(){
  			public void onClick(View v){
  				tDialog.dismiss();
  			}
  		});
  		
  	}

Jiqiu reason ah ! !

------ Solution ---------------------------------------- ----
Intentservice
child thread can not operate the UI thread.

I also found this problem that I wanted to display a dialog box with INTENTSERVICE how do I

ah . I was so used currently . But would like to replace that method I asked . Not like I do not change it. Changed so that it would listen to the radio activity .
------ eference --------------------------------------- < br> intentservice after the completion of the implementation of the method will automatically call stopself so can not be used to end his
