Android自带的对话框标题不好看，如果我们需要给弹出的对话框设置一个自己定义的标题，可以使用AlertDialog.Builder的setCustomTitle()方法。

定义一个对话框标题的title.xml文件：

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:background="@color/white"

android:gravity="center_vertical"

android:orientation="vertical" >

android:id="@+id/patient_top"

android:layout_width="match_parent"

android:layout_height="50dp"

android:layout_alignParentTop="true"

android:background="@color/green"

android:gravity="center_vertical|center_horizontal"

android:orientation="vertical" >

android:id="@+id/txtPatient"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="选择城市"

android:textColor="@color/white"

android:textSize="20sp" />

MainActivity的布局文件：

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:gravity="center_vertical|center_horizontal"

android:orientation="vertical"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="com.hzhi.dialogtest.MainActivity" >

android:id="@+id/btn01"

android:layout_width="150dp"

android:layout_height="wrap_content"

android:text="选择城市1" />

android:id="@+id/btn02"

android:layout_width="150dp"

android:layout_height="wrap_content"

android:text="选择城市2" />

MainActivity.java文件：

package com.hzhi.dialogtest;

import android.support.v7.app.ActionBarActivity;

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 ActionBarActivity implements OnClickListener{

final String[] cities = new String[6];

Button button_01, button_02;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

initView();

}

private void initView(){

cities[0] = "北京";

cities[1] = "上海";

cities[2] = "深圳";

cities[3] = "广州";

cities[4] = "杭州";

cities[5] = "成都";

button_01 = (Button) findViewById(R.id.btn01);

button_01.setOnClickListener(this);

button_02 = (Button) findViewById(R.id.btn02);

button_02.setOnClickListener(this);

}

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()){

case R.id.btn01:

AlertDialog.Builder builder1 = new AlertDialog.Builder(MainActivity.this);

builder1.setItems(cities, new DialogInterface.OnClickListener()

{

@Override

public void onClick(DialogInterface dialog, int which)

{

}

});

builder1.setTitle("选择城市");

builder1.show();

break;

case R.id.btn02:

LayoutInflater layoutInflater = LayoutInflater.from(MainActivity.this);

View mTitleView = layoutInflater.inflate(R.layout.title, null);

AlertDialog.Builder builder2 = new AlertDialog.Builder(MainActivity.this);

builder2.setItems(cities, new DialogInterface.OnClickListener()

{

@Override

public void onClick(DialogInterface dialog, int which)

{

}

});

builder2.setCustomTitle(mTitleView);

builder2.show();

break;

}

}

}

运行效果如下，左边是点击第一个按钮，弹出Android系统自带的对话框(直接用setTitle()设置标题)；右边是点击第二个按钮，首先inflate一个View，然后用setCustomTitle()方法把该View设置成对话框的标题。
