main.xml:

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical" android:layout_width="fill_parent"android:layout_height="fill_parent"><Button    android:id="@+id/btn"    android:layout_height="wrap_content"    android:layout_width="wrap_content"    android:text="查找网络连接"/>    </LinearLayout>

.java代码如下：

package org.lxh.demo;import android.app.Activity;import android.app.AlertDialog;import android.app.Dialog;import android.app.ProgressDialog;import android.content.DialogInterface;import android.os.Bundle;import android.view.LayoutInflater;import android.view.View;import android.view.View.OnClickListener;import android.widget.AdapterView;import android.widget.AdapterView.OnItemClickListener;import android.widget.AdapterView.OnItemSelectedListener;import android.widget.Button;import android.widget.Spinner;import android.widget.TextView;public class Hello extends Activity {private Button btn = null;private static final int MAX_PROGRESS=100;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState); // 生命周期方法super.setContentView(R.layout.main); // 设置要使用的布局管理器this.btn = (Button) super.findViewById(R.id.btn);this.btn.setOnClickListener(new OnClickListenerImpl());}private class OnClickListenerImpl implements OnClickListener {public void onClick(View v) {final ProgressDialog proDialog=new ProgressDialog(Hello.this);proDialog.setTitle("搜索网络");proDialog.setMessage("请耐心等待...");proDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);proDialog.setMax(MAX_PROGRESS);proDialog.setProgress(30);proDialog.setButton("后台处理", new DialogInterface.OnClickListener() {public void onClick(DialogInterface arg0, int arg1) {proDialog.dismiss();}});proDialog.onStart();new Thread(){public void run(){for(int x=0;x<MAX_PROGRESS;x++){try {Thread.sleep(500);} catch (InterruptedException e) {e.printStackTrace();}proDialog.incrementProgressBy(1);}proDialog.dismiss();}}.start();proDialog.show();}}}
