在Android中確定ProgressDialog

Question

我想要有一個ProgressDialog確定進度欄，而不是默認微調器。這似乎很容易：ProgressDialog有方法setIndeterminate，方法show接受布爾值來指示不確定性。但這些方式對我不起作用！該對話框仍然與微調不確定。如何改變行爲？

Answer 1

您需要致電：

progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); 

查看官方開發指南Showing a progress bar與連接到該部分的示例源代碼。

Answer 2

ProgressDialog dialog = new ProgressDialog(this); 
dialog.setMessage("Registering. Please wait..."); 
dialog.setIndeterminate(true); 
dialog.setCancelable(false); 
dialog.show(); 

Try this code should work fine... 

Answer 3

Oh Sorry.. Try this 

1) Create a layout file with below code 

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" android:id="@+id/RelativeLayout_DownloadProgress" android:paddingLeft="20dp" android:paddingBottom="20dp" android:paddingRight="10dp" android:paddingTop="20dp"> 
    <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/downloading_video_tv" android:text="@string/downloading_video" android:textStyle="bold" android:textColor="@color/COLOR_WHITE"></TextView> 
    <TextView android:layout_height="wrap_content" android:layout_width="wrap_content" android:id="@+id/download_progress_tv" android:text="@string/zero_percent" android:layout_below="@+id/downloading_video_tv" android:textColor="@color/COLOR_WHITE"></TextView> 

    <Button 
     android:id="@+id/download_cancel_btn" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_alignParentRight="true" 
     android:layout_below="@+id/downloading_video_tv" 
     android:text="@string/Cancel" 
     android:textColor="@color/COLOR_CANCEL_BTN" android:layout_marginLeft="5dp"> 
</Button> 

    <ProgressBar 
     android:id="@+id/download_progressbar" 
     style="?android:attr/progressBarStyleHorizontal" 
     android:layout_width="fill_parent" 
     android:layout_height="13dp" 
     android:layout_below="@id/download_progress_tv" 
     android:layout_toLeftOf="@id/download_cancel_btn" 
     android:indeterminateOnly="false" 
     android:max="100" 
     android:progressDrawable="@drawable/dwnld_progress" > 

</ProgressBar> 


</RelativeLayout> 



2) In your code do the following 

    i) in oncreate() method add the following lines.. 
     //Download progress layout inflate 
     RelativeLayout relativelayout_DownloadProgress = (RelativeLayout)_inflater.inflate(R.layout.downloadprogress, null); 
     TextView downloadProgress_PercentageTV = (TextView)relativelayout_DownloadProgress.findViewById(R.id.download_progress_tv); 
     Button downloadProgress_CancelBtn = (Button)relativelayout_DownloadProgress.findViewById(R.id.download_cancel_btn); 
     ProgressBar download_progressBar = (ProgressBar)relativelayout_DownloadProgress.findViewById(R.id.download_progressbar); 
     downloadProgress_CancelBtn.setOnClickListener(new OnClickListener() {   
      public void onClick(View v) { 
       // TODO Auto-generated method stub 

       dismissDialog(0); 
      } 
     }); 
    ii) //Creating Dialogs i.e., below onCreate() method 
    protected Dialog onCreateDialog(int id) { 
     switch (id) { 
     case 0: 
      return new AlertDialog.Builder(_activity) 
      .setView(relativelayout_DownloadProgress) 
      .create(); 
     }//switch end 
     return null; 
    }//onCreateDialog() 

    iii) on any click event add the following lines. 
    showDialog(0);download_progressBar.setProgress(0); 


Sorry i know its too long code but its working code in application...Try it might need modifications like variables must be declared in class scope.
