Android中用GridView实现九宫格

http://blog.csdn.net/shakespeare001/article/details/7768455

实现一个继承BaseAdapter的 ImageAdapter

java代码如下：

[java] view
plaincopy

package com.test;



import android.app.Activity;

import android.content.Context;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

import android.widget.AdapterView;

import android.widget.BaseAdapter;

import android.widget.GridView;

import android.widget.ImageView;

import android.widget.TextView;

import android.widget.Toast;

import android.widget.AdapterView.OnItemClickListener;



public class GridViewActivity extends Activity {



//存放各功能图片

private Integer[] mFunctionPics = {R.drawable.mobilesecurity,R.drawable.infosecurity,

R.drawable.no_interrupt,R.drawable.bianjiejieting,R.drawable.xiaomishu

,R.drawable.sms_send_attime,R.drawable.yule,R.drawable.setting};

//存放各功能的名称

private Integer[] mFunctionName = {R.string.phone_tools_box_name1,

R.string.phone_tools_box_name2,R.string.phone_tools_box_name3,

R.string.phone_tools_box_name4,R.string.phone_tools_box_name5,

R.string.phone_tools_box_name6,R.string.phone_tools_box_name7,

R.string.phone_tools_box_name8};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.gridview_main);



GridView girdview = (GridView) this.findViewById(R.id.girdview);

girdview.setAdapter(new ImageAdapter(this));

girdview.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView<?> parent, View view,

int position, long id) {

Toast.makeText(GridViewActivity.this, "图片ID："+mFunctionPics[position],1).show();

}

});



}



public class ImageAdapter extends BaseAdapter{



private Context mContext;

private LayoutInflater inflater;

private class GirdTemp{

ImageView phone_function_pic;

TextView phone_function_name;

}

public ImageAdapter(Context c){

mContext = c;

inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}

@Override

public int getCount() {

return mFunctionPics.length;

}



@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) {

GirdHolder holder;

if(convertView == null){

convertView = inflater.inflate(R.layout.gridview_item, null);

holder = new GirdHolder ();

holder.phone_function_pic = (ImageView) convertView.findViewById(R.id.function_view);

holder.phone_function_name = (TextView) convertView.findViewById(R.id.function_name);

convertView.setTag(holder);

}else{

holder = (GirdHolder) convertView.getTag();

}

holder.phone_function_pic.setImageResource(mFunctionPics[position]);

holder.phone_function_name.setText(mFunctionName[position]);

return convertView;

}



}



}

girdview_main.xml代码如下：

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

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

android:id="@+id/gridview"

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:numColumns="auto_fit"
//自动适应多少行

android:verticalSpacing="20dp"
//两行之间的距离

android:horizontalSpacing="20dp"
//两列之间的距离

android:gravity="center"

/>

girdview_item.xml源码：

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

<RelativeLayout

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

android:layout_height="wrap_content"

android:layout_width="fill_parent"

<ImageView>

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:id="@+id/function_view"

android:layout_centerHorizontal="true"

</ImageView>

<TextView

android:layout_width="wrap_content"

android:layout_below="@+id/function_view"

android:layout_height="wrap_content"


android:layout_centerHorizontal="true"

android:id="@+id/function_name">

</TextView>

</RelativeLayout>
