【Android】GridView添加网格线

GridView网格布局，默认情况下是没有网格线的

查找网上资料，找到了一种为GridView添加网格线的小技巧

实际上，该网格线是通过设置GridView各子项的间隔，并分别设置GridView背景色与子项背景色实现的。

实现方法

设置GridView背景色，设置水平间方向间隔属性值android:horizontalSpacing和竖直方向间隔属性值android:verticalSpacing
设置GridView子项背景色

示例代码： main.xml Xml代码

Main.java Java代码

packagedyingbleed.iteye;
importandroid.app.Activity;
importandroid.content.Context;
importandroid.graphics.Color;
importandroid.os.Bundle;
importandroid.view.Gravity;
importandroid.view.View;
importandroid.view.ViewGroup;
importandroid.view.ViewGroup.LayoutParams;
importandroid.widget.AbsListView;
importandroid.widget.BaseAdapter;
importandroid.widget.GridView;
importandroid.widget.TextView;
publicclassMainextendsActivity{
privateGridViewgrid;
@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
grid=(GridView)findViewById(R.id.main_GridView);
grid.setAdapter(newGridViewAdapter(this));
}
privateclassGridViewAdapterextendsBaseAdapter{
privateContextcontext;
publicGridViewAdapter(Contextcontext){
this.context=context;
}
intcount=100;
@Override
publicintgetCount(){
returncount;
}
@Override
publicObjectgetItem(intposition){
returnposition;
}
@Override
publiclonggetItemId(intposition){
returnposition;
}
@Override
publicViewgetView(intposition,ViewconvertView,ViewGroupparent){
TextViewresult=newTextView(context);
result.setText("Item"+position);
result.setTextColor(Color.BLACK);
result.setTextSize(24);
result.setLayoutParams(newAbsListView.LayoutParams(newLayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)));
result.setGravity(Gravity.CENTER);
result.setBackgroundColor(Color.WHITE);//设置背景颜色
returnresult;
}
}
}
