3、MainActivity中的代码：

package com.example.lession16_dialog; import android.os.Bundle; import android.os.Handler; import android.os.Message; import android.app.Activity; import android.app.AlertDialog; import android.app.ProgressDialog; import android.content.DialogInterface; import android.view.Menu; import android.view.View; import android.widget.Toast; public class MainActivity extends Activity { public Handler handler; private static final int MAX_PROGRESS=100; private static final int PRO=10; private int progress=10; private ProgressDialog progressDialog; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @SuppressWarnings("deprecation") public void openDialog(View v) { handler=new Handler(){ @Override public void handleMessage(Message msg) { super.handleMessage(msg); switch (msg.what) { case PRO: if(progress>=MAX_PROGRESS){ //重新设置 progress=0; progressDialog.dismiss(); //销毁对话框 }else{ progress++; progressDialog.incrementProgressBy(1); //延迟发送消息 handler.sendEmptyMessageDelayed(PRO, 100); } break; default: break; }} }; progressDialog=new ProgressDialog(this); progressDialog.setIcon(R.drawable.ic_launcher); progressDialog.setTitle("正在处理数据。。。"); progressDialog.setMessage("请稍后。。"); progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL); //设置进度条对话框//样式（水平，旋转）//进度最大值 progressDialog.setMax(MAX_PROGRESS); progressDialog.setButton("暂停",new DialogInterface.OnClickListener() {@Override public void onClick(DialogInterface dialog, int which) { //删除消息队列 handler.removeMessages(PRO); } }); progressDialog.setButton2("取消",new DialogInterface.OnClickListener() {@Override public void onClick(DialogInterface dialog, int which) { //删除消息队列 handler.removeMessages(PRO); //恢复进度条初始值 progress=0; progressDialog.setProgress(progress); } }); //显示 progressDialog.show(); //必须设置到show之后 progress=(progress>0)?progress:0; progressDialog.setProgress(progress); //线程 handler.sendEmptyMessage(PRO); } public void test1() { new AlertDialog.Builder(this) .setIcon(R.drawable.ic_launcher) .setTitle("xxxx") .setMessage("是否创建文件") .setPositiveButton("确认", new DialogInterface.OnClickListener() {@Override public void onClick(DialogInterface dialog, int which) { // 创建文件 new AlertDialog.Builder(MainActivity.this).setMessage( "文件已经被创建").show(); } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() {@Override public void onClick(DialogInterface dialog, int which) { new AlertDialog.Builder(MainActivity.this) .setMessage("您已经选择了取消的按钮,该文件不会被创建").create() .show(); } }).show(); } public void test2() { // 创建对话框 AlertDialog alertDialog = new AlertDialog.Builder(this).create(); // 设置对话框的标题 alertDialog.setTitle("xxxx"); // 设置对话框的内容 alertDialog.setMessage("消息"); // 显示对话框 alertDialog.show(); } public void test3() { AlertDialog alertDialog = new AlertDialog.Builder(this) .setTitle("xxxx").setMessage("啊大声大声道").show(); } public void test4() { final String items[] = { "Java", "Php", "3G", ".Net" }; new AlertDialog.Builder(this).setTitle("简单列表对话框") .setItems(items, new DialogInterface.OnClickListener() {@Override public void onClick(DialogInterface dialog, int which) { // 第一个参数dialog int which 条目 Toast.makeText(getApplicationContext(), "aaa" + items[which], Toast.LENGTH_LONG).show(); } }).show(); } public void test5(){ final String items[]={"JAVA",".NET","3G","PHP"}; new AlertDialog.Builder(this).setTitle("单选列表对话框") //数字2代表的是数组的下标 .setSingleChoiceItems(items, 2, new DialogInterface.OnClickListener() {@Override public void onClick(DialogInterface dialog, int which) { //第一个参数 dialogint which那个条目 Toast.makeText(getApplicationContext(), "xxxxx"+items[which], Toast.LENGTH_LONG).show(); } }).show(); } public void test6(){ final String items[]={"JAVA",".NET","PHP","3G"}; new AlertDialog.Builder(this).setTitle("多选列表对话框的简单实现") .setMultiChoiceItems(items, new boolean[]{false, true,true,true},new DialogInterface.OnMultiChoiceClickListener() {@Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { Toast.makeText(getApplicationContext(), "sad"+items[which], Toast.LENGTH_LONG).show(); } }).show(); }}
