GridView 网格布局 使用[url]http://www.iteye.com/topic/571184[/url]
[color=red]1.普通的GridView[/color]
main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />

    <GridView
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:numColumns="3" >
    </GridView>

</LinearLayout>

ImageAdapder.java

package com.gv;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;

public class ImageAdapder extends BaseAdapter {
	private Context context;
	private int[] images;

	public ImageAdapder(Context context,int[] images){
		this.context = context;
		this.images = images;
	}
	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return images.length;
	}

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

	@Override
	public long getItemId(int position) {
		// TODO Auto-generated method stub
		return 0;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		ImageView imageView = new ImageView(context);
		imageView.setImageResource(images[position]);
		return imageView;
	}

}

Activity类

-------------

package com.gv;

import android.app.Activity;
import android.os.Bundle;
import android.widget.GridView;

public class GridViewActivity extends Activity {
	private GridView gridView1;
	private int[] images = new int[] { R.drawable.android0001, R.drawable.android0002, R.drawable.android0003, R.drawable.android0004, R.drawable.android0005, R.drawable.android0006, R.drawable.android0007, R.drawable.android0008 };
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        gridView1 = (GridView)findViewById(R.id.gridView1);
        gridView1.setAdapter(new ImageAdapder(this,images));

    }
}

[color=red]2.带ImageView & TextView的GridView[/color]

main.xml [没变]

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView android:id="@+id/myTextView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />

    <GridView
        android:id="@+id/gridView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:numColumns="3" >
    </GridView>

</LinearLayout>

sub.xml [单个grid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:orientation="vertical" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/android0001" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="TextView" />

</LinearLayout>
