也是项目需要大家先来看看效果图
就是这样不过我的项目可能下面没有这么多项而已，说一下思路：
实际上下面展开的哪一块是被隐藏起来了的，可以获取itme的事件点击，接收点击事件展开（显示出来），点击另外的隐藏起来
下面是我的效果图（大家可以自己设置样式，我的比较丑）
好图片有点大，但是看的爽对不！下面贴代码
public class MainActivity extends Activity {
private ListView mListView;
private ListAdapter mAdapter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mListView = (ListView) findViewById(R.id.list);
mAdapter = new ListAdapter(this, listener, listener2, listener3);
mListView.setAdapter(mAdapter);
//mListView.setOnItemClickListener(this);
}
// @Override
// public void onItemClick(AdapterView<?> parent, View view, int position,
// long id) {
// mAdapter.changeImageVisable(position);
// }
MyClickListener listener = new MyClickListener() {
@Override
public void myOnClick(int position, View v) {
Toast.makeText(MainActivity.this, "修改", 2000).show();
}
};
MyClickListener2 listener2 = new MyClickListener2() {
public void myOnClick2(int position, View v) {
Toast.makeText(MainActivity.this, "重置", 2000).show();
}
};
MyClickListener3 listener3 = new MyClickListener3() {
@Override
public void myOnClick3(int position, View v) {
mAdapter.changeImageVisable(position);
}
};
}
Activity的xml代码：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
适配器代码：
public class ListAdapter extends BaseAdapter {
private Context mContext;
private int mLastPosition = -1;
private MyClickListener mListener;
private MyClickListener2 mListener2;
private MyClickListener3 mListener3;
public ListAdapter(Context context, MyClickListener mListener,
MyClickListener2 mListener2, MyClickListener3 mListener3) {
this.mContext = context;
this.mListener = mListener;
this.mListener2 = mListener2;
this.mListener3 = mListener3;
}
@Override
public int getCount() {
return 100;
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
