一个Android开发中经常使用对话框的小样例，共同拥有五种对话框：普通弹出对话框，单选对话框，多选对话框，输入对话框及进度条样式对话框：
<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" >
<Button
android:id="@+id/common_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="普通对话框"
android:textSize="16sp"
android:layout_marginTop="10dp" />
<Button
android:id="@+id/radio_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="单选对话框"
android:textSize="16sp"
android:layout_marginTop="10dp" />
<Button
android:id="@+id/check_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="多选对话框"
android:textSize="16sp"
android:layout_marginTop="10dp" />
<Button
android:id="@+id/input_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="输入文字对话框"
android:textSize="16sp"
android:layout_marginTop="10dp" />
<Button
android:id="@+id/progress_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="进度条对话框"
android:textSize="16sp"
android:layout_marginTop="10dp" />
</LinearLayout>
以下是输入内容的简单布局activity_input.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<EditText
android:id="@+id/uname"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />
<EditText
android:id="@+id/upass"
android:layout_width="fill_parent"

</LinearLayout>
