標籤：tco   osi   linear   OLE   進度條   tostring   onclick   cat   image   

先展示一下四種對話方塊的：

普通對話方塊

 

單選對話方塊：

 

多選對話方塊：

 

進度條對話方塊：

 

 

 

一個簡單的布局，放四個按鈕：

<LinearLayout 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:orientation="vertical"    tools:context=".MainActivity" >    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="click1"        android:text="普通對話方塊" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="click2"        android:text="單選對話方塊" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="click3"        android:text="多選對話方塊" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:onClick="click4"        android:text="進度條對話方塊" /></LinearLayout>
