这是合理的活动：

       android:layout_width="wrap_content" 
       android:layout_height="wrap_content"

您好请尝试下面的参考链接进度条tutorials.Hope它应该对你有帮助。您可以下载示例源代码并在您的应用程序中尝试。

Progress Bar

Progress bar for downloading a file

Android Progress Bar Example

嗨这里我补充从服务器的代码示例下载文件。请检查并让我知道。

import java.io.InputStream; 
    import java.net.URL; 
    import android.app.Activity; 
    import android.app.ProgressDialog; 
    import android.os.Bundle; 
    import android.util.Log; 
    import android.view.View; 
    import android.widget.Button; 
    import java.io.BufferedInputStream; 
    import java.io.FileOutputStream; 
    import java.io.OutputStream; 
    import java.net.URLConnection; 
    import android.app.Dialog; 
    import android.graphics.drawable.Drawable; 
    import android.os.AsyncTask; 
    import android.os.Environment; 
    import android.widget.ImageView; 

    public class download extends Activity { 

     // button to show progress dialog 
     Button btnShowProgress; 

     // Progress Dialog 
     private ProgressDialog pDialog; 
     ImageView my_image; 
     // Progress dialog type (0 - for Horizontal progress bar) 
     public static final int progress_bar_type = 0; 

     // File url to download 
     private static String file_url = "http://alshbab90.softsmedia.com/helmi_1.mp3"; 

     @Override 
     public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     // show progress bar button 
     btnShowProgress = (Button) findViewById(R.id.btnProgressBar); 
     // Image view to show image after downloading 
     my_image = (ImageView) findViewById(R.id.my_image); 
     /** 
     * Show Progress bar click event 
     * */ 
      btnShowProgress.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
      // starting new Async Task 
      new DownloadFileFromURL().execute(file_url); 
      } 
     }); 
     } 

     /** 
     * Showing Dialog 
     * */ 
     @Override 
     protected Dialog onCreateDialog(int id) { 
     switch (id) { 
     case progress_bar_type: // we set this to 0 
      pDialog = new ProgressDialog(this); 
      pDialog.setMessage("Downloading file. Please wait..."); 
      pDialog.setIndeterminate(false); 
      pDialog.setMax(100); 
      pDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); 
      pDialog.setCancelable(true); 
      pDialog.show(); 
      return pDialog; 
     default: 
      return null; 
     } 
     } 

     /** 
     * Background Async Task to download file 
     * */ 
     class DownloadFileFromURL extends AsyncTask<String, String, String> { 

     /** 
     * Before starting background thread 
     * Show Progress Bar Dialog 
     * */ 
     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
      showDialog(progress_bar_type); 
     } 

     /** 
     * Downloading file in background thread 
     * */ 
     @Override 
     protected String doInBackground(String... f_url) { 
      int count; 
      try { 
      URL url = new URL(f_url[0]); 
      URLConnection conection = url.openConnection(); 
      conection.connect(); 
      // this will be useful so that you can show a tipical 0-100% progress bar 
      int lenghtOfFile = conection.getContentLength(); 

      // download the file 
      InputStream input = new BufferedInputStream(url.openStream(), 8192); 

      // Output stream 
      OutputStream output = new FileOutputStream("/sdcard/helmi_1.mp3"); 

      byte data[] = new byte[1024]; 

      long total = 0; 

      while ((count = input.read(data)) != -1) { 
       total += count; 
       // publishing the progress.... 
       // After this onProgressUpdate will be called 
       publishProgress(""+(int)((total*100)/lenghtOfFile)); 

       // writing data to file 
       output.write(data, 0, count); 
      } 

      // flushing output 
      output.flush(); 

      // closing streams 
      output.close(); 
      input.close(); 

      } catch (Exception e) { 
      Log.e("Error: ", e.getMessage()); 
      } 

      return null; 
     } 

     /** 
     * Updating progress bar 
     * */ 
     protected void onProgressUpdate(String... progress) { 
      // setting progress percentage 
      pDialog.setProgress(Integer.parseInt(progress[0])); 
      } 

     /** 
     * After completing background task 
     * Dismiss the progress dialog 
     * **/ 
     @Override 
     protected void onPostExecute(String file_url) { 
      // dismiss the dialog after the file was downloaded 
      dismissDialog(progress_bar_type); 

      // Displaying downloaded image into image view 
      // Reading image path from sdcard 
       String imagePath = Environment.getExternalStorageDirectory().toString() + "/helmi_1.mp3"; 
      // setting downloaded into image view 
      my_image.setImageDrawable(Drawable.createFromPath(imagePath)); 
     } 

     } 
    } 

创建的main.xml：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<!-- Download Button --> 
<Button android:id="@+id/btnProgressBar" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:text="Download File with Progress Bar" 
    android:layout_marginTop="50dip"/> 

<!-- Image view to show image after downloading --> 
<ImageView android:id="@+id/my_image" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"/> 

</LinearLayout> 

需要补充的AndroidManifest.xml许可的，

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

希望它应该对你有帮助。请尝试让我知道。谢谢
