自定义Dialog是每个android 爱屁屁几乎都会用到的。于是乎最为一个android人我也自定义了一个Dialog.效果见图

这个运行效果是在华为大屏手机上，But,当我兴致勃勃的将代码部署到老红米（红米一代，最老版本的红米）上时，和我预想的差了不止一点啊看图：

敢问这一道蓝色的线是什么鬼？？我看看了代码，将设置的透明背景去掉，离奇的发现，这条蓝色的线是标题和正文分割线。去掉这根线也不是什么难事，只需要在原来的代码上加上几行代码就搞定了。

看代码：

package com.homenet.androidclient.dialog;import android.app.Dialog;import android.content.Context;import android.graphics.Color;import android.os.Bundle;import android.view.Gravity;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.view.Window;import android.view.WindowManager;import android.widget.BaseAdapter;import android.widget.GridView;import android.widget.ImageButton;import android.widget.TextView;import com.homenet.androidclient.R;import com.homenet.androidclient.bean.UserBean;import java.util.List;/** * Description： 房屋设施弹出框<br/> * Copyright (c) ,${year} , janson <br/> * This program is protected by copyright laws. <br/> * Program Name:${file_name} <br/> * Date: 2016-10-26 * @author 史元睿 * @version : 1.0 */public class EquDialog extends Dialog{    private Context context;    private GridView gridView;    private ImageButton mydelect;    private MyEquAdapter adapter;    private List<String> list=UserBean.devices;    public EquDialog(Context context, List<String> devices) {        super(context);        this.context = context;        setContentView(R.layout.dialog_equ);        Window window = getWindow();        WindowManager.LayoutParams params = window.getAttributes();        params.gravity = Gravity.CENTER;        window.setBackgroundDrawableResource(android.R.color.transparent);        window.setAttributes(params);        setCanceledOnTouchOutside(true);                  //上面的代码，是用来去除Holo主题的蓝色线条
         try{            int dividerID=context.getResources().getIdentifier("android:id/titleDivider", null, null);            View divider=findViewById(dividerID);            divider.setBackgroundColor(Color.TRANSPARENT);        }catch(Exception e){                     e.printStackTrace();        }    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        gridView= (GridView) findViewById(R.id.dialog_gv);        mydelect= (ImageButton) findViewById(R.id.dialog_delect);        mydelect.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                EquDialog.this.dismiss();            }        });        adapter=new MyEquAdapter(context,list);        gridView.setAdapter(adapter);    }} class MyEquAdapter extends BaseAdapter{     private Context context;     private List<String> list=UserBean.devices;     public MyEquAdapter() {     }     public MyEquAdapter(Context context,List<String> list) {         this.context = context;         this.list=list;     }     //用一个方法来获取数据源     public void setList(Context context,List<String> list) {         this.context = context;         this.list = list;     }     public List<String> getList() {         return list;     }     @Override    public int getCount() {        return list.size();    }    @Override    public Object getItem(int position) {        return position;    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder;        if(convertView==null){            holder=new ViewHolder();            convertView = LayoutInflater.from(context).inflate(R.layout.equ_gv_item, null);            holder.tv= (TextView) convertView.findViewById(R.id.equ_gv_item_tv);            convertView.setTag(holder);        }else {            holder = (ViewHolder) convertView.getTag();        }        holder.tv.setText(list.get(position));        return convertView;    }     class ViewHolder{         private TextView tv;     }}

没错，一个try catch 就搞定，现在任凭你在那个手机上都是没有那条讨厌的蓝色线。
这个自定义Dialog 布局如下：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:gravity="center"    android:layout_gravity="center"    android:background="@color/transparent">    <LinearLayout        android:layout_width="280dp"        android:layout_height="330dp"        android:orientation="vertical"        android:layout_marginLeft="15dp"        android:layout_marginRight="15dp"        android:background="@color/white">        <!--房屋配套设施-->        <TextView            android:layout_width="match_parent"            android:layout_height="40dp"            android:text="房屋配套设施"            android:gravity="center_vertical"            android:layout_marginLeft="15dp"            android:textColor="@color/black"/>        <View            android:layout_width="match_parent"            android:layout_height="1dp"            android:background="@color/gainsboro"/>                <GridView            android:id="@+id/dialog_gv"            android:layout_width="wrap_content"            android:background="@color/white"            android:layout_height="wrap_content"            android:layout_marginTop="15dp"            android:layout_marginLeft="15dp"            android:layout_marginRight="15dp"            android:clickable="true"            android:clipChildren="true"            android:columnWidth="35dp"            android:listSelector="@null"            android:numColumns="3"            android:paddingBottom="1dp"            android:stretchMode="columnWidth"            android:verticalSpacing="1dp"></GridView>    </LinearLayout>    <ImageButton        android:id="@+id/dialog_delect"        android:layout_width="20dp"        android:layout_height="20dp"        android:layout_marginTop="20dp"        android:background="@mipmap/delect"/></LinearLayout>
