Android自帶的對話框標題不好看,如果我們需要給彈出的對話框設置一個自己定義的標題,可以使用AlertDialog.Builder的setCustomTitle()方法。 定義一個對話框標題的title.xml文件: <?xml version="1.0" encoding="UTF-8"?>
Android自帶的對話框標題不好看,如果我們需要給彈出的對話框設置一個自己定義的標題,可以使用AlertDialog.Builder的setCustomTitle()方法。
定義一個對話框標題的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" > <LinearLayout 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" > <TextView android:id="@+id/txtPatient" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="選擇城市" android:textColor="@color/white" android:textSize="20sp" /> </LinearLayout> </LinearLayout>
MainActivity的佈局文件:
<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" > <Button android:id="@+id/btn01" android:layout_width="150dp" android:layout_height="wrap_content" android:text="選擇城市1" /> <Button android:id="@+id/btn02" android:layout_width="150dp" android:layout_height="wrap_content" android:text="選擇城市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; @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] = "廣州"; 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("選擇城市"); 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; } } }
運行效果如下,左邊是點擊第一個按鈕,彈出Android系統自帶的對話框(直接用setTitle()設置標題);右邊是點擊第二個按鈕,首先inflate一個View,然後用setCustomTitle()方法把該View設置成對話框的標題。
