android對話方塊介紹2 自訂對話方塊

1，在layout下定義login.xml自訂登入視圖，代碼如下：

<?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="fill_parent"    android:orientation="vertical"    android:baselineAligned="false"  ><LinearLayout   android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:orientation="horizontal"    android:layout_weight="1"    >     <TextView        android:layout_width="60dp"        android:textSize="15sp"        android:layout_height="wrap_content"        android:text="@string/username" />     <EditText         android:id="@+id/username"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:hint="@string/hintname"                 /></LinearLayout><LinearLayout   android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:orientation="horizontal"    android:layout_weight="1"    >     <TextView        android:layout_width="60dp"        android:textSize="15sp"        android:layout_height="wrap_content"        android:text="@string/password" />     <EditText         android:id="@+id/password"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:hint="@string/hintpassword"         /></LinearLayout>       </LinearLayout>

2，編寫java代碼，這裡是通過一個按鈕調用的自訂對話方塊，按鈕id為dialog5

case R.id.dialog5:LayoutInflater inflater = LayoutInflater.from(DialogDemoActivity.this);View view = inflater.inflate(R.layout.login, null);//注意，這裡從擴充的視圖中取得username和password視圖控制項username = (EditText) view.findViewById(R.id.username);password = (EditText) view.findViewById(R.id.password);new AlertDialog.Builder(DialogDemoActivity.this).setTitle("自訂對話方塊").setView(view)//自訂視圖.setPositiveButton("確定", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {String userName = username.getText().toString();String passWord = password.getText().toString();Toast.makeText(DialogDemoActivity.this, userName+","+passWord, 1).show();}}).setNegativeButton("取消", new DialogInterface.OnClickListener() {public void onClick(DialogInterface dialog, int which) {// TODO Auto-generated method stub}}).setCancelable(false).show();break;

3,自訂對話方塊效果

4，點擊確定按鈕，將會顯示輸入的使用者名稱和密碼
