android中九宫格布局与gridview

纵观现在的应用程序,九宫格是非常常见的一种布局方式。很多优秀的手机应用程序都采用了这一布局。下面就android中九宫格布局方式的实现和大家做一个简单的介绍。

首先在youxi.xml的布局

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

>

<TextView

android:layout_width="50dp"

android:layout_height="45dp"

android:gravity="center"

android:id="@+id/textview"

android:background="@drawable/sanguosss"

/>

</RelativeLayout>

然后是gridview.xml的布局

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:gravity="center"

android:background="@drawable/biaoge"

>

<GridView

android:layout_width="200dp"

android:layout_height="400dp"

android:numColumns="5"

android:id="@+id/gridview"

android:horizontalSpacing="0dp"

android:verticalSpacing="0dp"

/>

<!-- android:layout_marginTop="5dp" -->

</LinearLayout>

最后是Adapter.java的内容

package cn.zs.service;

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import cn.zs.lianliankan.R;

import android.app.Activity;

import android.os.Bundle;

import android.widget.GridView;

import android.widget.SimpleAdapter;

public class youxi extends Activity {

private String[] text={"啊","放","啊","放","啊","放","放","啊",

"啊","放","啊","放","啊","放","啊","放","啊","放","啊","放","啊","放",

"放","啊","放","啊","放","啊","放","啊","放","啊","啊","放","啊","啊",

"放","啊","放","啊"};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.gridview);

GridView gridView=(GridView) findViewById(R.id.gridview);

List<HashMap<String, Object>> data=new ArrayList<HashMap<String,Object>>();

for(int i=0;i<text.length;i++){

HashMap<String, Object> item=new HashMap<String, Object>();

item.put("name",text[i]);

data.add(item);

}

SimpleAdapter simpleAdapter=new SimpleAdapter(getApplicationContext(), data, R.layout.youxi, new String[]{"name"},new int[]{R.id.textview});

gridView.setAdapter(simpleAdapter);

}

}
