這篇文章主要為大家詳細(xì)介紹了Android實(shí)現(xiàn)彈窗進(jìn)度條效果，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

Android自定義進(jìn)度條主要是修改ProgressBar的style，彈窗則是在Dialog里顯示ProgressBar。

直接上代碼。

在style.xml里加入如下代碼：

<style name="ProgressBar_Mini" parent="@android:style/Widget.ProgressBar.Horizontal"> 
  <item name="android:maxHeight">50dip</item> 
  <item name="android:minHeight">8dip</item> 
  <item name="android:indeterminateOnly">false</item> 
  <item name="android:indeterminateDrawable">@android:drawable/progress_indeterminate_horizontal</item> 
  <item name="android:progressDrawable">@drawable/progressbar_mini</item> 
</style> 
<style name="dialog" parent="@android:style/Theme.Dialog"> 
  <item name="android:windowFrame">@null</item> 
  <item name="android:windowIsFloating">true</item> 
  <item name="android:windowIsTranslucent">true</item> 
  <item name="android:windowNoTitle">true</item> 
  <item name="android:backgroundDimEnabled">true</item> 
  <item name="android:windowBackground">@color/transparent</item> 
 </style>

新建drawable/progressbar_mini.xml內(nèi)容如下：

<layer-list xmlns:android="http://schemas.android.com/apk/res/android" > 
 <item android:id="@android:id/background"> 
  <shape> 
   <corners android:radius="0dip" /> 
   <gradient 
    android:angle="270" 
    android:centerY="0.75" 
    android:endColor="#F5F5F5" 
    android:startColor="#BEBEBE" /> 
  </shape> 
 </item> 
 
 <item android:id="@android:id/secondaryProgress"> 
  <clip> 
   <shape> 
    <corners android:radius="0dip" /> 
    <gradient 
     android:angle="270" 
     android:centerY="0.75" 
     android:endColor="#165CBC" 
     android:startColor="#85B0E9" /> 
   </shape> 
  </clip> 
 </item> 
 
 <item android:id="@android:id/progress"> 
  <clip> 
   <shape> 
    <corners android:radius="0dip" /> 
    <gradient 
     android:angle="270" 
     android:centerY="0.75" 
     android:endColor="#00FF66" 
     android:startColor="#00FF66" /> 
   </shape> 
  </clip> 
 </item> 
</layer-list>

myprogressbar.xml的內(nèi)容如下：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 android:background="@drawable/back_qian" 
 android:gravity="center" 
 android:orientation="vertical" > 
 
 <TextView 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:gravity="center" 
  android:text="正在切換狀態(tài)...." 
  android:textSize="18sp" 
  android:textColor="@color/black" /> 
 
 <TextView 
  android:layout_width="fill_parent" 
  android:layout_height="wrap_content" 
  android:gravity="center" 
  android:text="" /> 
 
<ProgressBar 
 android:id="@+id/progressBar1"  
 style="@style/ProgressBar_Mini" 
 android:layout_width="290dp" 
 android:layout_height="17dp" /> 
  
</LinearLayout>

MyProgressBar.java的內(nèi)容如下：

package com.wl.util; 
 
import android.app.Dialog; 
import android.content.Context; 
import android.content.DialogInterface; 
import android.content.DialogInterface.OnCancelListener; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.widget.ProgressBar; 
 
import com.wl.R; 
 
public class MyProgressBar { 
 Dialog dialog; 
 Context context; 
 // 聲明ProgressBar對(duì)象 
 private ProgressBar pro1; 
  
 
 /** 
  * 構(gòu)造 
  */ 
 public MyProgressBar(Context context) { 
  // TODO Auto-generated constructor stub 
  this.context = context; 
  dialog = new Dialog(context, R.style.dialog); 
  dialog.setOnCancelListener(onCancelListener); 
 } 
 
 /** 
  * 初始化進(jìn)度對(duì)話框 
  */ 
 public void initDialog() { 
 
  LayoutInflater inflater = (LayoutInflater) context 
    .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
  View view = inflater.inflate(R.layout.myprogressbar, null); 
  dialog.setContentView(view); 
  pro1 = (ProgressBar) dialog.findViewById(R.id.progressBar1); 
  // 設(shè)置進(jìn)度條是否自動(dòng)旋轉(zhuǎn),即設(shè)置其不確定模式,false表示不自動(dòng)旋轉(zhuǎn) 
  pro1.setIndeterminate(false); 
  // 設(shè)置ProgressBar的最大值 
  pro1.setMax(100); 
 
  // 設(shè)置ProgressBar的當(dāng)前值 
  pro1.setProgress(0); 
 
   
  dialog.show(); 
 } 
 
 public void setProgress(int progressValue) { 
  pro1.setProgress(progressValue); 
 } 
  
 public void colseDialog() { 
  dialog.dismiss(); 
 } 
 
 public boolean isShowing() { 
  if (dialog.isShowing()) { 
   return true; 
  } else { 
   return false; 
  } 
 } 
 
 OnCancelListener onCancelListener = new OnCancelListener() { 
  @Override 
  public void onCancel(DialogInterface dialog) { 
   // TODO Auto-generated method stub 
   dialog.dismiss(); 
  } 
 }; 
}

調(diào)用代碼如下：

MyProgressBar myProgressBar; 
myProgressBar = new MyProgressBar(Dialog_TestActivity.this); 
myProgressBar.initDialog(); 
    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      // TODO Auto-generated method stub 
 
 
      try { 
       Thread.sleep(200); 
      } catch (InterruptedException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
      } 
      for (int i = 0; i < 100; i++) { 
       handler.sendEmptyMessage(0); 
       try { 
        Thread.sleep(30); 
       } catch (InterruptedException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      } 
     } 
    }).start(); 
Handler handler = new Handler() { 
  @Override 
  public void handleMessage(Message msg) { 
   // 改變ProgressBar的當(dāng)前值 
   myProgressBar.setProgress(intCounter++); 
   if (intCounter == 100) { 
    intCounter = 0; 
    myProgressBar.colseDialog(); 
   } 
  }  
 };

按返回退出：

@Override 
 public void onBackPressed() { 
  // TODO Auto-generated method stub 
  Log.d("11", "onBackPressed()"); 
 
  if (myProgressDialog.isShowing()) { 
   myProgressDialog.colseDialog(); 
  } 
  if (myProgressBar.isShowing()) { 
   myProgressBar.colseDialog(); 
  } 
 
  super.onBackPressed(); 
 }
