三部分：

1）在MainActivity中

               	private RidingDialog ridingDialog;
                ridingDialog = new RidingDialog(IndexActivity.this,R.style.new_dialog);
                //第一步  new一个Dialog(context,style）外框样式
		ridingDialog.setRidingTimeOnClickListtener(new RidingTimeOnClickListtener() {
			@Override
			public void RidingTimeOnClick(String time,String ridingTime) {
				index_starttime.setText(ridingTime);//返回数据显示在TextView上
				TIME = time; //乘车时段用0 1 2 3 4 传到接口
			}
		});
                //第二步  设立接口的Listener
              		index_starttime.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View view) {
				// TODO Auto-generated method stub
				ridingDialog.show();
			}
		});
                //第三步  调用显示出Dialog

2) 外框样式 R.Style.new

    <style name="new_dialog" parent="@android:style/Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <!-- 边框 -->
        <item name="android:windowIsFloating">true</item>
        <!-- 是否悬浮在activity上 -->
        <item name="android:windowIsTranslucent">false</item>
        <!-- 半透明 -->
        <item name="android:windowNoTitle">true</item>
        <!-- 无标题 -->
        <item name="android:windowBackground">@android:color/transparent</item>
        <!-- 背景透明 -->
        <item name="android:backgroundDimEnabled">true</item>
        <!-- 模糊 -->
        <item name="android:backgroundDimAmount">0.5</item>
        <!-- 灰度 -->
        <item name="android:windowContentOverlay">@null</item>
        <!-- 对话框是否有遮盖 -->

        <item name="android:colorBackgroundCacheHint">@null</item>
    </style>

3）自定义的Dialog extends Dialog

3.1）setContentView(R.layout.dialog_ridingtime) 设置Dialog内部布局上面一步是设置Dialog的外框布局Style

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="@drawable/ridingtime_shape"
        android:gravity="center_vertical"
        android:paddingLeft="10dp"
        android:text="@string/ridingtime"
        android:textColor="#ffffff"
        android:textSize="18sp" />

    <RadioGroup
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical" >

        <RadioButton
            android:id="@+id/ridingtime_all"
            style="@style/ridingtime_radiobuttonStyle"
            android:text="00:00 - 24:00 全天" />

        <TextView style="@style/grayline_Style" />

        <RadioButton
            android:id="@+id/ridingtime_zerotosix"
            style="@style/ridingtime_radiobuttonStyle"
            android:text="00:00 - 06:00 早晨" />

        <TextView style="@style/grayline_Style" />

        <RadioButton
            android:id="@+id/ridingtime_sixtotwelve"
            style="@style/ridingtime_radiobuttonStyle"
            android:text="06:00 - 12:00 上午" />

        <TextView style="@style/grayline_Style" />

        <RadioButton
            android:id="@+id/ridingtime_twelvetoeighteenth"
            style="@style/ridingtime_radiobuttonStyle"
            android:text="12:00 - 18:00 下午" />

        <TextView style="@style/grayline_Style" />

        <RadioButton
            android:id="@+id/ridingtime_eighteenthtotwentyfourth"
            style="@style/ridingtime_radiobuttonStyle"
            android:background="@drawable/ridingtimebottom_selector"
            android:text="18:00 - 24:00 晚上" />
    </RadioGroup>

</LinearLayout>

3.2) 如何设置回调接口

	private RidingTimeOnClickListtener ridingTimeOnClickListtener;
        /**
        * 设置乘车时间监听对象
        * @param ridingTimeOnClickListtener 回调接口对象
        */
        public void setRidingTimeOnClickListtener(RidingTimeOnClickListtener ridingTimeOnClickListtener){
               this.ridingTimeOnClickListtener = ridingTimeOnClickListtener;
              }
        /**
         * 选择乘车时间的回调接口
         */
         public interface RidingTimeOnClickListtener{
              void RidingTimeOnClick(String TIME , String ridingTime);
	         }

        //简而言之 也就是

        private AAOnClickListener aaOnClickListener;
        
        public void setAAOnClickListener(AAOnClcikListener aaOnClickListener){
              this.aaOnClickListener=aaOnClickListener;  }
        
        public  interface AAOnClickListener{
                 void  AAOnClick(XXX xxx,XXX xxx);
             }
        //对应Activity中 setAAOnClickListener(new AAOnClickListener(){
        //                                                @Override
        //                                                public void AAOnClick(){...}
        //                                              });

总的代码:
