android 自訂對話方塊

建立一個布局檔案 my_dialog.xml

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    >        <TextView         android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentTop="true"        android:layout_marginTop="4dp"        android:text="@string/textView1"        />        <EditText         android:id="@+id/editText_user"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_alignLeft="@+id/textView1"        android:layout_below="@+id/textView1"        android:layout_marginTop="4dp"        />         <TextView         android:id="@+id/textView2"        android:layout_width="wrap_content"        android:layout_height="wrap_content"   android:layout_alignLeft="@+id/editText_user"        android:layout_below="@+id/editText_user"        android:layout_marginTop="7dp"        android:text="@string/textView2"        />        <EditText         android:id="@+id/editText_pwd"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_alignLeft="@+id/textView2"        android:layout_marginTop="4dp"        android:layout_below="@+id/textView2"        /></RelativeLayout>

以下是strings.xml檔案：

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="app_name">demo091801</string>    <string name="action_settings">Settings</string>    <string name="hello_world">Hello world!</string>        <string name="MyDialog">自訂對話方塊</string>    <string name="textView1">使用者名稱</string>        <string name="textView2">密碼</string></resources>

在主activity_main.xml中添加一個按鈕控制項，當單擊此按鈕時即彈出自訂的對話方塊：

<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"    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=".MainActivity" >  <Button       android:id="@+id/My_Dialog"      android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:text="@string/MyDialog"      /></RelativeLayout>

圖形介面如下：

在MainActivity.java代碼中為按鈕控制項設定單擊事件監聽，並彈出自訂的對話方塊：

MainActivity.java:

package com.example.demo091801;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;public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);Button btn1 = (Button)findViewById(R.id.My_Dialog);btn1.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stubAlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);LayoutInflater inflater = getLayoutInflater();View view = inflater.inflate(R.layout.my_dialog, null);builder.setTitle("登陸");builder.setView(view);builder.setPositiveButton("登陸", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stub}});builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface arg0, int arg1) {// TODO Auto-generated method stub}});AlertDialog dialog = builder.create();dialog.show();}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}}
