android自定义弹出框样式实现

做项目时，感觉android自带的弹出框样式比较丑，很多应用都是自己做的弹出框，这里也试着自己做了一个。

废话不说先上图片：



实现机制

1.先自定义一个弹出框的样式

2.自己实现CustomDialog类，继承自Dialog，实现里面方法，在里面加载自定义样式的弹出框；

3.使用时，与使用Dialog一样

具体代码

dialog_normal_layout.xml样式文件

  1. <?xml version="1.0" encoding="utf-8"?>  
  2. <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"  
  3.     android:layout_width="fill_parent"  
  4.     android:layout_height="fill_parent"  
  5.     android:clickable="true"  
  6.     android:orientation="vertical"  
  7.     android:padding="20.0dip" >  
  8.   
  9.     <LinearLayout  
  10.         android:layout_width="fill_parent"  
  11.         android:layout_height="wrap_content"  
  12.         android:layout_gravity="center"  
  13.         android:background="@drawable/bg_bombbox"  
  14.         android:orientation="vertical" >  
  15.   
  16.         <TextView  
  17.             android:id="@+id/title"  
  18.             style="@style/text_18_ffffff"  
  19.             android:layout_width="fill_parent"  
  20.             android:layout_height="40.0dip"  
  21.             android:gravity="center"  
  22.             android:text="@string/title_alert"  
  23.             android:visibility="visible" />  
  24.   
  25.         <TextView  
  26.             android:id="@+id/message"  
  27.             style="@style/text_16_666666"  
  28.             android:layout_width="fill_parent"  
  29.             android:layout_height="wrap_content"  
  30.             android:gravity="left|center"  
  31.             android:lineSpacingMultiplier="1.5"  
  32.             android:minHeight="120.0dip"  
  33.             android:paddingBottom="15.0dip"  
  34.             android:paddingLeft="20.0dip"  
  35.             android:paddingRight="20.0dip"  
  36.             android:paddingTop="15.0dip" />  
  37.   
  38.         <View  
  39.             android:layout_width="fill_parent"  
  40.             android:layout_height="1.0px"  
  41.             android:background="#ffd0d0d0" />  
  42.   
  43.         <LinearLayout  
  44.             android:layout_width="fill_parent"  
  45.             android:layout_height="60.0dip"  
  46.             android:layout_gravity="bottom"  
  47.             android:background="@drawable/dialog_bottom_bg"  
  48.             android:gravity="center"  
  49.             android:orientation="horizontal" >  
  50.   
  51.             <Button  
  52.                 android:id="@+id/positiveButton"  
  53.                 style="@style/text_15_ffffff_sdw"  
  54.                 android:layout_width="114.0dip"  
  55.                 android:layout_height="40.0dip"  
  56.                 android:background="@drawable/btn_ok_selector"  
  57.                 android:gravity="center"  
  58.                 android:text="@string/ok" />  
  59.   
  60.             <Button  
  61.                 android:id="@+id/negativeButton"  
  62.                 style="@style/text_15_666666_sdw"  
  63.                 android:layout_width="114.0dip"  
  64.                 android:layout_height="40.0dip"  
  65.                 android:layout_marginLeft="20.0dip"  
  66.                 android:background="@drawable/btn_cancel_selector"  
  67.                 android:gravity="center"  
  68.                 android:text="@string/cancel" />  
  69.         </LinearLayout>  
  70.     </LinearLayout>  
  71.   
  72. </FrameLayout>

  170.                 // add the contentView to the dialog body  
  171.                 ((LinearLayout) layout.findViewById(R.id.message))  
  172.                         .removeAllViews();  
  173.                 ((LinearLayout) layout.findViewById(R.id.message)).addView(  
  174.                         contentView, new LayoutParams(  
  175.                                 LayoutParams.WRAP_CONTENT,  
  176.                                 LayoutParams.WRAP_CONTENT));  
  177.             }  
  178.             dialog.setContentView(layout);  
  179.             return dialog;  
  180.         }  
  181.   
  182.     }  
  183. }  

使用代码

  1. CustomDialog.Builder builder = new CustomDialog.Builder(this);  
  2.         builder.setMessage("这个就是自定义的提示框");  
  3.         builder.setTitle("提示");  
  4.         builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {  
  5.             public void onClick(DialogInterface dialog, int which) {  
  6.                 dialog.dismiss();  
  7.                 //设置你的操作事项  
  8.             }  
  9.         });  
  10.   
  11.         builder.setNegativeButton("取消",  
  12.                 new android.content.DialogInterface.OnClickListener() {  
  13.                     public void onClick(DialogInterface dialog, int which) {  
  14.                         dialog.dismiss();  
  15.                     }  
  16.                 });  
  17.   
  18.         builder.create().show();  

至此，自定义弹出框已经完成，是不是感觉很简单呢。
