簡簡單單取代Gallery--horizontalscrollview用法

經過這幾天的爬文,總算解決Gallery廢棄的問題

利用horizontalscrollview+LinearLayout+ImageView這三種

做法就是在horizontalscrollview內塞一個LinearLayout,然後利用迴圈把ImageView全部塞入LinearLayout,成品如下圖所示

import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup.LayoutParams;

import com.example.pj3.R;

public class Anothergallery extends Activity implements ViewFactory {
    
    //原圖
        private Integer[] imgArr = {
                R.drawable.d1b, R.drawable.d2b, R.drawable.d3b, R.drawable.d4b,

        private Integer[] thumbImgArr = {
                R.drawable.d1, R.drawable.d2, R.drawable.d3, R.drawable.d4,
                R.drawable.d5, R.drawable.d6, R.drawable.d7, R.drawable.d8,

        };
        
        private LinearLayout linelay;
        private ImageSwitcher imgSwi2;
        
        
        
        
        @Override
        public void onCreate(Bundle savedInstanceState){
            super.onCreate(savedInstanceState);
            setContentView(R.layout.anothergallery);
            
            
            linelay = (LinearLayout)findViewById(R.id.anogallery);
            
            imgSwi2 = (ImageSwitcher)findViewById(R.id.imgSw2);
            imgSwi2.setFactory(this);
            imgSwi2.setInAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_in));
            imgSwi2.setOutAnimation(AnimationUtils.loadAnimation(this, android.R.anim.fade_out));
            
            
            
            for(int i=0; i < thumbImgArr.length; i++)
            {
                    linelay.addView(getImageView(i));
                    
            }
        }
        
        private ImageView getImageView(int i){
            ImageView img = new ImageView(this);
            img.setImageResource(thumbImgArr[i]);
            img.setId(i);
            img.setOnClickListener(new View.OnClickListener(){
                public void onClick(View v)
                {
                    imgSwi2.setImageResource(imgArr[v.getId()]);
                    Toast.makeText(v.getContext(), "您選擇了"+(v.getId()+1), Toast.LENGTH_SHORT).show();
                }
            });
            
            return img;
        }
        
        
        public View makeView(){
            ImageView v1 = new ImageView(this);
            v1.setBackgroundColor(0xFF000000);
            v1.setScaleType(ImageView.ScaleType.FIT_CENTER);
            v1.setLayoutParams(new ImageSwitcher.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
            return v1;
        }
