Android开发图片滚动效果，供大家参考，具体内容如下
效果图：
设置适配来设置图片位置大小
package com.example.gallary;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Gallery;
import android.widget.ImageView;
public class ImageAdapter extends BaseAdapter {
private Context mContext; // 图片数组源
private Integer[] imgs = { R.drawable.img1, R.drawable.img2, R.drawable.img3, R.drawable.img4, R.drawable.img5, R.drawable.img6, R.drawable.img7};
public ImageAdapter(Context c) { mContext = c; }
@Override
public int getCount() { return imgs.length; } // 获取图片位置
@Override
public Object getItem(int position) { return imgs[position]; } // 获取图片ID
@Override
public long getItemId(int position) { return position; }
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageview = new ImageView(mContext);
imageview.setImageResource(imgs[position]);
imageview.setLayoutParams(new Gallery.LayoutParams(240, 200)); // 设置布局 图片120×120显示
imageview.setScaleType(ImageView.ScaleType.CENTER); // 设置显示比例类型（不缩放）
return imageview; }
}
mAIn添加图片资源
package com.example.gallary;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.Gallery;
import android.widget.Toast;
public class MainActivity extends Activity {
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Gallery gallery = (Gallery) findViewById(R.id.gallery);
gallery.setAdapter(new ImageAdapter(this)); // gallery添加ImageAdapter图片资源
}
}
布局
<TextView android:id="@+id/tv" android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:layout_gravity="center" android:layout_marginTop="50dip" android:textColor="#ffff0000" android:textSize="30sp" android:text="滚动图片"/> <Gallery android:id="@+id/gallery" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="10dip" android:layout_below="@id/tv" />
drawable放置图片资源
