Gallery的另类用法 类似GridView横向滚动

Gallery是个非常强大的控件，但是一般都把它当作显示图片之用。其实只要定制适配器，Gallery可以放进任何控件（显示图片就是放了ImageView）。我本来是想要GridView横向滚动的效果，但是实现起来好像比较麻烦，而Gallery本来就是横向滚动的，只要稍稍修改适配器即可。下面的例子把数据定死了，只需稍稍修改一下，把数据数组作为参数传入即可。 适配器代码:

package com.test;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Gallery;
import android.widget.TextView;

public class GallleryAdapter extends BaseAdapter
{
     private Context context;  
     String[] s=new String[]{"第一集","第一集","第一集","第一集","第一集","第一集","第一集"};
    @Override
    public int getCount()
    {
        // TODO Auto-generated method stub
        return s.length;
    }
    public GallleryAdapter(Context c) {  
        context = c;  
        
    }  
    @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)
    {
        // TODO Auto-generated method stub
        TextView tv=new TextView(context);
        tv.setText(s[position]);
        tv.setLayoutParams(new Gallery.LayoutParams(120, 120));  
        return tv;
    }
    

}

Activity代码:

package com.test;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Gallery;
import android.widget.TextView;
import android.widget.AdapterView.OnItemSelectedListener;

public class AndroidTestActivity extends Activity {
    /** Called when the activity is first created. */
    Gallery gallery1;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        gallery1=(Gallery)findViewById(R.id.gallery1);
        gallery1.setAdapter(new GallleryAdapter(this));  
        gallery1.setOnItemSelectedListener(new OnItemSelectedListener(){

            @Override
            public void onItemSelected(AdapterView parent, View view, int position, long id)
            {
                // TODO Auto-generated method stub
                //默认情况下，选中或没选中的项，文字颜色都是灰色的，但是被选中的反而要淡一点
                //为了能更突出被选中项，把没选中的设为灰色，选中的设为红色
                Gallery ga=(Gallery)parent;
                for(int i=0;i parent)
            {
                // TODO Auto-generated method stub
                
            }});
    }
}
