Layout设置

GridView：网格视图

1. android:gravity="center"居中
2. android:verticalSpacing="20dp"垂直调整
3. android:horizontalSpacing="10dp"水平调整
4. android:numColumns=“3” 显示一行为几个视图

// An highlighted block
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainPangActivity" >

    <TextView
        android:id="@+id/textView1"

添加适配器

// A code block
<?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:orientation="vertical" >

    <ImageView
        android:id="@+id/main2_photo"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:src="@drawable/yu" />

    <TextView
        android:id="@+id/main2_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="@string/main_title_txz" />

</LinearLayout>

基本适配器

public class MainGridAdapter1 extends BaseAdapter {
    
    

	//定义上下文
	Context context;
	//图片
	int[] icon = new int[]{
    
    R.drawable.yu,R.drawable.zhaf,R.drawable.zhcs}; 
	//功能名称
	String[] prin = {
    
    "服务","超市","安防"};
	
	public MainGridAdapter(Context context) {
    
    
		super();
		this.context = context;
	}

	@Override
	public int getCount() {
    
    
		// TODO Auto-generated method stub
		return icon.length;
	}

	@Override
	public Object getItem(int  position) {
    
    
		// TODO Auto-generated method stub
		return icon[position];
	}

	@Override
	public long getItemId(int  position) {
    
    
		// TODO Auto-generated method stub
		return  position;
	}

	@Override
	public View getView(int  position, View viewarg, ViewGroup parent) {
    
    
		// TODO Auto-generated method stub
		if (viewarg == null) {
    
    
			viewarg = LayoutInflater.from(context).inflate(R.layout.main_titles_xs, null);
		    ImageView imageView = (ImageView) viewarg.findViewById(R.id.main2_photo);
		    TextView title = (TextView) viewarg.findViewById(R.id.main2_text);
		    imageView.setImageResource(icon[position]);
		    title.setText(prin[position]);
		}
		return viewarg;
	}
