Android常用的五種彈出對話框

一個Android開發中常用對話框的小例子，共有五種對話框：普通彈出對話框，單選對話框，多選對話框，輸入對話框及進度條樣式對話框：

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >


android:id="@+id/common_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="普通對話框"
android:textSize="16sp"
android:layout_marginTop="10dp" />


android:id="@+id/radio_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="單選對話框"
android:textSize="16sp"
android:layout_marginTop="10dp" />


android:id="@+id/check_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="多選對話框"
android:textSize="16sp"
android:layout_marginTop="10dp" />


android:id="@+id/input_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="輸入文字對話框"
android:textSize="16sp"
android:layout_marginTop="10dp" />


android:id="@+id/progress_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="進度條對話框"
android:textSize="16sp"
android:layout_marginTop="10dp" />


 

下面是輸入內容的簡單布局activity_input.xml

xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >


android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />


android:id="@+id/uname"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />


android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/hello_world" />


android:id="@+id/upass"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
