Answer 3

u有另一个选择，设计了xml layout为您的对话框如何ürequird并把它在你的活动

示例XML：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="215dp" 
android:layout_height="wrap_content" 
android:layout_gravity="center" 
android:background="@drawable/custom_alert" 
android:orientation="vertical" > 

<TextView 
    android:id="@+id/tv_header" 
    android:layout_width="fill_parent" 
    android:layout_height="26dp" 
    android:gravity="center" 
    android:text="@string/oops" 
    android:textColor="#3f3f3f" 
    android:textSize="15sp" 
    android:textStyle="bold" 
    /> 

<TextView 
    android:id="@+id/tv_description" 
    android:layout_width="fill_parent" 
    android:layout_height="58dp" 
    android:layout_below="@+id/tv_header" 
    android:gravity="center" 
    android:textColor="#747474" 
    android:textSize="10sp" 
    android:typeface="sans" /> 

<View 
    android:id="@+id/separator" 
    android:layout_width="fill_parent" 
    android:layout_height="1dip" 
    android:layout_above="@+id/tv_actionbtn" 
    android:layout_centerVertical="true" 
    android:background="#b8b8b8" /> 

<TextView 
    android:id="@+id/tv_actionbtn" 
    android:layout_width="fill_parent" 
    android:layout_height="40dp" 
    android:layout_below="@+id/tv_description" 
    android:gravity="center" 
    android:textColor="#d61820" 
    android:textSize="15sp" 
    android:typeface="sans" /> 

custom_alert背景布局：

<corners android:color="#FFFFFF" /> 

<solid android:color="#FFFFFF" /> 

<stroke 
    android:width="3dip" 
    android:color="#FFFFFF" /> 

<corners 
    android:radius="20dip" 
    android:color="#FFFFFF" /> 

<padding 
    android:bottom="0dip" 
    android:left="0dip" 
    android:right="0dip" 
    android:top="0dip" /> 

这里是活动代码

dialog = new Dialog(Activity.this); 
     dialog.setContentView(R.layout.customdialog); 

     dialog.getWindow().setBackgroundDrawable(
       new ColorDrawable(android.graphics.Color.TRANSPARENT)); 
     txtHeader = (TextView) dialog.findViewById(R.id.requiredheader); 
     txtDiscription = (TextView) dialog.findViewById(R.id.requireddescription; 
     txtHeader.setText(getResources().getString(R.string.conneting_server)); 
     txtDiscription.setText(getResources().getString(R.string.logging_in)); 
     dialog.setCancelable(false); 
     dialog.show();
