android创建自定义对话框

创建如下自定义对话框:

JAVA代码

LayoutInflater li = LayoutInflater.from(TagActivity. this); //NOTE
final View TestView = li.inflate(R.layout.tag_dialog, null);
dialog = new Dialog(TagActivity. this, R.style.dialog);
dialog.setContentView(TestView);
dialog.setCancelable( true);
dialog.show();

R.layout.tag_dialog如下

<?xml version= "1.0" encoding= "utf-8" ?>
<LinearLayout xmlns:android= "http://schemas.android.com/apk/res/android" android:layout_width= "match_parent" android:layout_height= "match_parent" android:orientation= "vertical" >
   <LinearLayout android:layout_height= "wrap_content" android:layout_width= "fill_parent" >
     <TextView android:id= "@+id/title" android:layout_height= "wrap_content" android:layout_width= "fill_parent" android:gravity= "center" android:textColor= "@color/white" android:paddingTop= "15dp" ></TextView>
   </LinearLayout>
   <LinearLayout android:layout_width= "200dp" android:layout_height= "200dp" android:orientation= "vertical" android:paddingLeft= "10dp" android:paddingRight= "10dp" android:paddingTop= "10dp" >
     <EditText android:id= "@+id/name" android:layout_width= "fill_parent" android:layout_height= "wrap_content" android:background= "@color/transparent" android:textColor= "@color/white" android:hint= "输入消息内容" android:textColorHint= "@color/white" ></EditText>
   </LinearLayout>
   <LinearLayout android:layout_width= "fill_parent" android:layout_height= "wrap_content" android:orientation= "horizontal" android:layout_marginBottom= "10dp" >
     <RelativeLayout android:layout_width= "fill_parent" android:layout_height= "wrap_content" android:layout_weight= "1" >
       <ImageButton android:id= "@+id/sure" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:src= "@drawable/sure" android:background= "@drawable/btn_click_background" android:layout_centerHorizontal= "true" ></ImageButton>
     </RelativeLayout>
     <RelativeLayout android:layout_width= "fill_parent" android:layout_height= "wrap_content" android:layout_weight= "1" >
       <ImageButton android:id= "@+id/cancel" android:layout_width= "wrap_content" android:layout_height= "wrap_content" android:src= "@drawable/cancel" android:background= "@drawable/btn_click_background" android:layout_centerHorizontal= "true" ></ImageButton>
     </RelativeLayout>
   </LinearLayout>
</LinearLayout>

R.style.dialog文件如下

<style name= "dialog" parent= "@android:style/Theme.Dialog" >
   <item name= "android:windowFrame" >@null </item>
   <item name= "android:windowIsFloating" >true </item>
   <item name= "android:windowIsTranslucent" >true </item>
