gallery(画廊)用来展示图片集合，将图片放入数据源中，传到适配器里。然后绑定视图。

xml文件：（width写成wrap_content的话，每次只显示一张图片）

<Gallery         android:id="@+id/gallery"        android:layout_width="match_parent"        android:layout_height="wrap_content"        />

main:

Gallery gallery = (Gallery) findViewById(R.id.gallery);//找到对象idfinal int[] images = {R.drawable.blue001,R.drawable.blue002,R.drawable.blue003,R.drawable.blue004,R.drawable.blue005,R.drawable.blue006,R.drawable.blue007,R.drawable.blue008};//将图片放入数组中

适配器，

BaseAdapter mAdapter = new BaseAdapter() {@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ImageView iv = new ImageView(MainActivity.this);iv.setImageResource(images[position]);//设置图片资源iv.setScaleType(ScaleType.FIT_XY);//设置填充方式iv.setLayoutParams(new Gallery.LayoutParams(500, 600));//布局return iv;}@Overridepublic long getItemId(int position) {return 0;}@Overridepublic Object getItem(int position) {return null;}@Overridepublic int getCount() {return images.length;}};

gallery.setSpacing(60);//设置每个图片间距gallery.setAnimationDuration(100);<span style="white-space:pre"></span>gallery.setGravity(Gravity.CENTER);//设置居中对齐gallery.setAdapter(mAdapter);gallery.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {Toast.makeText(getApplicationContext(), ""+position, 0).show();}});
