示例：
一、确定对话框
AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("确认对话框"); builder.setIcon(R.drawable.icon_72); builder.setMessage("这里是对话框内容"); builder.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface arg0, int arg1) { // TODO Auto-generated method stub Toast.makeText(AlertDialog_text.this, "点击了确定按钮", 1).show(); } }); AlertDialog dialog = builder.create(); dialog.show(); //显示、
二、普通列表
final String[] items = new String[]{"语文","数学","英语","物理","化学"}; //列表项 Builder alertdialog = new AlertDialog.Builder(this); alertdialog.setTitle("你喜欢的课程").setItems(items, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Toast.makeText(AlertDialog_lianxi.this, items[which], Toast.LENGTH_SHORT).show(); } }); alertdialog.create().show(); //创建显示列表
三、单选列表
final String[] items_fruit = new String[]{"苹果","香蕉","橘子","西瓜","梨"}; Builder alerdialog = new AlertDialog.Builder(this); //设置列表标题 alerdialog.setTitle("你喜欢的水果"); //设置单选列表 alerdialog.setSingleChoiceItems(items_fruit, 0, new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub Toast.makeText(AlertDialog_lianxi.this, items_fruit[which], Toast.LENGTH_SHORT).show(); } }); //设置取消按钮并且设置响应事件 alerdialog.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub //取消按钮响应事件 } }); //添加确定按钮 并且设置响应事件 alerdialog.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub //确定按钮响应事件 } }); alerdialog.create().show();//创建显示列表
四、多选列表
final String[] items_fruit1 = new String[]{"苹果","香蕉","橘子","西瓜","梨"}; //设置项 final boolean[] items_fruit_selected = new boolean[]{true,false,false,false,false}; Builder alerdialog1 = new AlertDialog.Builder(this); //设置列表标题 alerdialog1.setTitle("你喜欢的水果"); //设置多选列表 alerdialog1.setMultiChoiceItems(items_fruit1, items_fruit_selected, new DialogInterface.OnMultiChoiceClickListener() { @Override public void onClick(DialogInterface dialog, int which, boolean isChecked) { // TODO Auto-generated method stub items_fruit_selected[which] = isChecked; } }); //设置取消按钮并且设置响应事件 alerdialog1.setNegativeButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub //取消按钮响应事件 } }); //添加确定按钮 并且设置响应事件,将选择的项显示 alerdialog1.setPositiveButton("确定", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub //确定按钮响应事件 StringBuilder stringBuilder = new StringBuilder(); for(int i=0;i<items_fruit_selected.length;i++) { if(items_fruit_selected[i] == true) { stringBuilder.append(items_fruit1[i]+"、"); } } Toast.makeText(AlertDialog_lianxi.this, stringBuilder.toString(), Toast.LENGTH_SHORT).show(); } }); alerdialog1.create().show();//创建显示列表
5、自定义布局对话框
对话框布局文件
<?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:gravity="center_horizontal" android:orientation="vertical" > <EditText android:layout_width="match_parent" android:layout_height="wrap_content" android:editable="false" android:text="自定义对话框"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="这里是自定义对话框的内容" android:textSize="20dp" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="确定" /> </LinearLayout> layout_dialog package com.example.demo1; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; public class MainActivity extends Activity { private Button btn_openDialog; private View view; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); btn_openDialog = (Button) findViewById(R.id.id_submit); btn_openDialog.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub view = LayoutInflater.from(MainActivity.this).inflate(R.layout.layout_dialog, null); AlertDialog dialog = new AlertDialog.Builder(MainActivity.this) .setTitle("主题") .setIcon(R.drawable.ic_launcher) .setView(view) .setPositiveButton("取消", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // TODO Auto-generated method stub } }) .create(); dialog.show(); } }); } } MainActivity.class
