Android开发中提示框Toast、AlertDialog的使用!

先了解一下AlertDialog.Builder创建对话框的几个常用方法:

setTitle() :设置标题
setIcon() :设置图标
setMessage():设置提示内容
setView() : 设置自定义视图
setItems() :设置对话框要显示的一个list
setMultiChoiceItems() :设置对话框显示的复选框
setNeutralButton() :普通按钮

setPositiveButton() :添加"Yes"按钮
setNegativeButton() :添加"No"按钮
create() : 创建对话框

show() :显示对话框

下面以一个例子简单演示一下其应用,先看一下效果图:

自定义视图:

 


代码示例如下:

一个主activity,两个布局文件;


ReviewCriteria.java

[java] 
package com.test.restaurantfinder; 
 
import android.app.Activity; 
import android.app.AlertDialog; 
import android.content.DialogInte易做图ce; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.Gravity; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.Toast; 
 
public class ReviewCriteria extends Activity { 
    private static final String tag = "reviewCriteria"; 
    private final String arrayFruit[] = new String[]{"apple","banana","pear"}; 
     
    private Button tishiButton = null;      //提示Toast的按钮  
    private Button tishiAlert = null;       //普通AlertDialog  
    private Button tishiAlertItem = null;   //类似ListItem  
    private Button AlertRadio = null;       //类似RadioButton  
    private int selectedFruitIndex = 0;      
     
    private Button CheckButton = null;      //类似CheckBox  
    final boolean[] arrayFruitSelected = new boolean[] {false, true, false}; //默认选中  
     
    private Button myCustomButton = null;       //自定义视图  
    private View myCustomView = null; 
     
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.activity_review_criteria); 
         
        this.tishiButton = (Button)findViewById(R.id.tishiButton); 
        this.tishiAlert = (Button)findViewById(R.id.tishiAlart); 
        this.tishiAlertItem = (Button)findViewById(R.id.AlertItem); 
        this.AlertRadio = (Button)findViewById(R.id.AlertSingleChoice); 
        this.CheckButton = (Button)findViewById(R.id.AlertCheckBox); 
        this.myCustomButton = (Button)findViewById(R.id.customView); 
         
        //Toast  
        this.tishiButton.setOnClickListener( 
                new OnClickListener(){ 
                    @Override 
                    public void onClick(View v){ 
                        Log.i(tag, "in onClick1"); 
                        /*注:在内嵌函数中使用时context 一定要对,不能只是this,而应该是Class.this或者getApplicationContext()*/ 
                        //Toast.makeText(ReviewCriteria.this, "this is a toast", Toast.LENGTH_LONG).show();  
                        Toast toast = Toast.makeText(ReviewCriteria.this, "this is a toast", Toast.LENGTH_SHORT); 
                        toast.setGravity(Gravity.CENTER, 0, 0); 
                        toast.show(); 
                    } 
                }); 
         
        //AlertDialog  
        this.tishiAlert.setOnClickListener( 
                new OnClickListener(){ 
                    public void onClick(View v){ 
                        new AlertDialog.Builder(ReviewCriteria.this). 
                        setIcon(R.drawable.ic_launcher).//图标  
                        setTitle("Delete?").//标题  
                        setMessage("this is a AlertDialog!").//提示内容  
                        setPositiveButton("Yes", new DialogInte易做图ce.OnClickListener() {//确定  
                            @Override
