Android自定義樣式的對話框

首先看下效果圖，確保是你想要的效果：

xml文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:background="@drawable/pop_bg"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/title"
        android:layout_width="fill_parent"
        android:layout_height="40.0dip"
        android:layout_marginTop="15dp"
        android:gravity="center"
        android:text="設置號碼"
        android:textColor="#fffffb"
        android:textSize="20sp"
        android:visibility="visible" />

  <!--   <LinearLayout
        android:id="@+id/contentView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" > -->

        <EditText
            android:id="@+id/number"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="5dp"
            android:gravity="left|center"
            android:hint="號碼" />
    <!-- </LinearLayout> -->


    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="60.0dip"
        android:layout_gravity="bottom"
        android:layout_marginTop="5dp"
        android:gravity="center"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/positiveButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/btn_ok_selector"
            android:gravity="center" />

        <Button
            android:id="@+id/negativeButton"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="20.0dip"
            android:background="@drawable/btn_cancel_selector"
            android:gravity="center" />
    </LinearLayout>

</LinearLayout>
