這篇文章主要介紹了Android中AlertDialog各種對(duì)話框的用法在項(xiàng)目開發(fā)中經(jīng)常用的到，本文給大家介紹的非常詳細(xì)，具有參考借鑒價(jià)值

目標(biāo)效果：

程序運(yùn)行，顯示圖一的幾個(gè)按鈕，點(diǎn)擊按鈕分別顯示圖二到圖六的對(duì)話框，點(diǎn)擊對(duì)話框的某一項(xiàng)或者按鈕，也會(huì)顯示相應(yīng)的吐司輸出。

1.activity_main.xml頁面存放五個(gè)按鈕。

activity_main.xml頁面：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".MainActivity" > 
<Button 
android:id="@+id/btnSure" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_marginTop="10dp" 
android:text="確認(rèn)對(duì)話框"/> 
<Button 
android:id="@+id/btnRadio" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_marginTop="60dp" 
android:text="單選對(duì)話框"/> 
<Button 
android:id="@+id/btnCheck" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_marginTop="110dp" 
android:text="多選對(duì)話框"/> 
<Button 
android:id="@+id/btnList" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_marginTop="160dp" 
android:text="列表對(duì)話框"/> 
<Button 
android:id="@+id/btnMy" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:layout_marginTop="210dp" 
android:text="自定義對(duì)話框"/> 
</RelativeLayout>

2.新建dialog.xml頁面，作為最后一個(gè)自定義對(duì)話框的布局頁面。

dialog.xml頁面：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:orientation="vertical" > 
<LinearLayout 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:orientation="horizontal" > 
<EditText 
android:id="@+id/edInput" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_weight="2" > 
<requestFocus /> 
</EditText> 
<Button 
android:id="@+id/btnOk" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:layout_weight="1" 
android:text="確定" /> 
</LinearLayout> 
<ImageView 
android:id="@+id/ivPicture" 
android:layout_width="wrap_content" 
android:layout_height="280dp" 
android:src="@drawable/white" /> 
<TextView 
android:id="@+id/textView1" 
android:layout_gravity="center" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:text="TextView" /> 
</LinearLayout>

3.MainActivity.java頁面處理對(duì)話框的彈出及點(diǎn)擊事件。

MainActivity.java頁面：

package com.example.alertdialog; 
import android.os.Bundle; 
import android.app.Activity; 
import android.app.AlertDialog; 
import android.content.DialogInterface; 
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 MainActivity extends Activity implements OnClickListener { 
private Button btnSure,btnRadio,btnCheck,btnList,btnMy; 
private String[] sexList={"男","女"};//單選列表 
private String[] likeList={"籃球","足球","打游戲","聽音樂","看電影"};//多選列表 
private String[] itemList={"項(xiàng)目經(jīng)理","策劃","測(cè)試","美工","程序員"};//列表 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.activity_main); 
getId();//獲取控件id 
click();//按鈕綁定點(diǎn)擊事件 
} 
/*獲取控件id*/ 
private void getId() { 
btnSure = (Button) findViewById(R.id.btnSure); 
btnRadio=(Button) findViewById(R.id.btnRadio); 
btnCheck=(Button) findViewById(R.id.btnCheck); 
btnList=(Button) findViewById(R.id.btnList); 
btnMy=(Button) findViewById(R.id.btnMy); 
} 
/*按鈕綁定點(diǎn)擊事件*/ 
private void click() { 
btnSure.setOnClickListener(this); 
btnRadio.setOnClickListener(this); 
btnCheck.setOnClickListener(this); 
btnList.setOnClickListener(this); 
btnMy.setOnClickListener(this); 
} 
@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
getMenuInflater().inflate(R.menu.main, menu); 
return true; 
} 
@Override 
public void onClick(View view) { 
switch (view.getId()) { 
case R.id.btnSure: 
showDialog1();//確認(rèn)對(duì)話框 
break; 
case R.id.btnRadio: 
showDialog2();//單選對(duì)話框 
break; 
case R.id.btnCheck: 
showDialog3();//多選對(duì)話框 
break; 
case R.id.btnList: 
showDialog4(); 
break; 
case R.id.btnMy: 
showDialog5(); 
break; 
} 
} 
/*確認(rèn)對(duì)話框*/ 
private void showDialog1() { 
AlertDialog.Builder builder=new AlertDialog.Builder(this); 
builder.setTitle("確認(rèn)對(duì)話框");//設(shè)置標(biāo)題 
builder.setIcon(R.drawable.ic_launcher);//設(shè)置圖標(biāo) 
builder.setMessage("確認(rèn)對(duì)話框提示內(nèi)容");//設(shè)置內(nèi)容 
/*添加對(duì)話框中確定按鈕和點(diǎn)擊事件*/ 
builder.setPositiveButton("確定",new DialogInterface.OnClickListener() { 
@Override 
public void onClick(DialogInterface arg0, int arg1) { 
Toast.makeText(MainActivity.this,"點(diǎn)擊了確定按鈕",Toast.LENGTH_SHORT).show(); 
} 
}); 
/*添加對(duì)話框中取消按鈕和點(diǎn)擊事件*/ 
builder.setNegativeButton("取消",new DialogInterface.OnClickListener() { 
@Override 
public void onClick(DialogInterface arg0, int arg1) { 
Toast.makeText(MainActivity.this,"點(diǎn)擊了取消按鈕",Toast.LENGTH_SHORT).show(); 
} 
}); 
AlertDialog dialog=builder.create();//獲取dialog 
dialog.show();//顯示對(duì)話框 
} 
/*單選對(duì)話框*/ 
private void showDialog2() { 
AlertDialog.Builder builder=new AlertDialog.Builder(this); 
builder.setTitle("性別");//設(shè)置標(biāo)題 
builder.setIcon(R.drawable.ic_launcher);//設(shè)置圖標(biāo) 
/*參數(shù)一位單選列表文字，參數(shù)二為默認(rèn)第幾個(gè)選中（-1默認(rèn)不選中），參數(shù)三是創(chuàng)建監(jiān)聽器*/ 
builder.setSingleChoiceItems(sexList,-1,new DialogInterface.OnClickListener() { 
@Override 
public void onClick(DialogInterface dialog, int which) { 
String sex=sexList[which]; 
Toast.makeText(MainActivity.this,"這個(gè)人性別為"+sex, Toast.LENGTH_SHORT).show(); 
} 
}); 
/*添加對(duì)話框中取消按鈕點(diǎn)擊事件*/ 
builder.setNegativeButton("取消",new DialogInterface.OnClickListener() { 
@Override 
public void onClick(DialogInterface dialog, int which) { 
dialog.dismiss();//關(guān)閉對(duì)話框 
} 
}); 
AlertDialog dialog=builder.create();//獲取dialog 
dialog.show();//顯示對(duì)話框 
} 
/*多選對(duì)話框*/ 
private void showDialog3() { 
AlertDialog.Builder builder=new AlertDialog.Builder(this); 
builder.setTitle("愛好");//設(shè)置標(biāo)題 
builder.setIcon(R.drawable.ic_launcher);//設(shè)置圖標(biāo) 
/*參數(shù)同單選對(duì)話框一樣，另外第二個(gè)參數(shù)默認(rèn)不選中為null，而不是-1*/ 
builder.setMultiChoiceItems(likeList,null,new DialogInterface.OnMultiChoiceClickListener() { 
@Override 
public void onClick(DialogInterface dialog, int which, boolean isChecked) { 
if(isChecked){ 
Toast.makeText(MainActivity.this,"我喜歡"+likeList[which],Toast.LENGTH_SHORT).show(); 
}else{ 
Toast.makeText(MainActivity.this,"我不喜歡"+likeList[which],Toast.LENGTH_SHORT).show(); 
} 
} 
}); 
/*添加對(duì)話框中取消按鈕點(diǎn)擊事件*/ 
builder.setNegativeButton("取消",new DialogInterface.OnClickListener() { 
@Override 
public void onClick(DialogInterface dialog, int which) { 
dialog.dismiss();//關(guān)閉對(duì)話框 
} 
}); 
AlertDialog dialog=builder.create();//獲取dialog 
dialog.show();//顯示對(duì)話框 
} 
/*列表對(duì)話框*/ 
private void showDialog4() { 
AlertDialog.Builder builder=new AlertDialog.Builder(this); 
builder.setTitle("部門列表");//設(shè)置標(biāo)題 
builder.setIcon(R.drawable.ic_launcher);//設(shè)置圖標(biāo) 
builder.setItems(itemList,new DialogInterface.OnClickListener() { 
@Override 
public void onClick(DialogInterface dialog, int which) { 
Toast.makeText(MainActivity.this,"我點(diǎn)擊了"+itemList[which],Toast.LENGTH_SHORT).show(); 
} 
}); 
AlertDialog dialog=builder.create();//獲取dialog 
dialog.show();//顯示對(duì)話框 
} 
/*自定義對(duì)話框*/ 
private void showDialog5() { 
LayoutInflater inflater=LayoutInflater.from(this); 
View view=inflater.inflate(R.layout.dialog,null);//獲取自定義布局 
AlertDialog.Builder builder=new AlertDialog.Builder(this); 
builder.setTitle("自定義對(duì)話框");//設(shè)置標(biāo)題 
builder.setIcon(R.drawable.ic_launcher);//設(shè)置圖標(biāo) 
builder.setView(view);//設(shè)置自定義樣式布局到對(duì)話框 
AlertDialog dialog=builder.create();//獲取dialog 
dialog.show();//顯示對(duì)話框 
} 
}

4.運(yùn)行就出現(xiàn)目標(biāo)效果了。

關(guān)于Android中AlertDialog各種對(duì)話框的用法就給大家介紹這么多，希望對(duì)大家有所幫助！
