Android有自带的对话框标题，但是不太美观，如果要给弹出的对话框设置一个自定义的标题，使用AlertDialog.Builder的setCustomTitle()方法。

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。

定义一个对话框标题的title.xml文件：

<?xml version="1.0" encoding="UTF-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"android:background="@color/white"android:gravity="center_vertical"android:orientation="vertical" ><LinearLayoutandroid: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" ><TextViewandroid: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" /></LinearLayout></LinearLayout>

MainActivity的布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"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" ><Buttonandroid:id="@+id/btn01"android:layout_width="150dp"android:layout_height="wrap_content"android:text="选择城市1" /><Buttonandroid:id="@+id/btn02"android:layout_width="150dp"android:layout_height="wrap_content"android:text="选择城市2" /></LinearLayout>

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;@Overrideprotected 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); }@Overridepublic void onClick(View v) {// TODO Auto-generated method stubswitch (v.getId()){case R.id.btn01:AlertDialog.Builder builder1 = new AlertDialog.Builder(MainActivity.this);builder1.setItems(cities, new DialogInterface.OnClickListener(){@Overridepublic 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(){@Overridepublic void onClick(DialogInterface dialog, int which){}});builder2.setCustomTitle(mTitleView);builder2.show();break;}} }

以上所述是小编给大家分享的Android使用setCustomTitle()方法自定义对话框标题，希望对大家有所帮助。
