自定义Dialog 去掉标题

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;

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。
