Android实现弹窗进度条效果

Android自定义进度条主要是修改ProgressBar的style，弹窗则是在Dialog里显示ProgressBar。

直接上代码。

在style.xml里加入如下代码：

 
  50dip 
  8dip 
  false 
  @android:drawable/progress_indeterminate_horizontal 
  @drawable/progressbar_mini 
 

 
  @null 
  true 
  true 
  true 
  true 
  @color/transparent 
  

新建drawable/progressbar_mini.xml内容如下：

myprogressbar.xml的内容如下：

MyProgressBar.java的内容如下：

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; 
 // 声明ProgressBar对象 
 private ProgressBar pro1; 
  
 
  
 public MyProgressBar(Context context) { 
  // TODO Auto-generated constructor stub 
  this.context = context; 
  dialog = new Dialog(context, R.style.dialog); 
  dialog.setonCancelListener(onCancelListener); 
 } 
 
  
 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); 
  // 设置进度条是否自动旋转,即设置其不确定模式,false表示不自动旋转 
  pro1.setIndeterminate(false); 
  // 设置ProgressBar的最大值 
  pro1.setMax(100); 
 
  // 设置ProgressBar的当前值 
  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(); 
  } 
 }; 
} 

调用代码如下：

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) { 
   // 改变ProgressBar的当前值 
   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(); 
 }
