Android listview子控件的的點擊事件

1.先看圖，是否是你想要的

                                       


2.佈局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/lin_img"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:descendantFocusability="blocksDescendants"----------------//加上這行
    >

  
    <ListView
    android:id="@+id/hot_listview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:cacheColorHint="#00000000"
    android:listSelector="#00000000"
    ></ListView>

</LinearLayout>

  descendantFocusability屬性的值有三種：

beforeDescendants：viewgroup會優先其子類控件而獲取到焦點

      afterDescendants：viewgroup只有當其子類控件不需要獲取焦點時才獲取焦點

      blocksDescendants：viewgroup會覆蓋子類控件而直接獲得焦點

子控件設置：android:focusable="false"

3.adapter類

public class Videoadapter extends BaseAdapter{
ArrayList<VideoInfoModel.DetailBean.VideosBean> mList;
Context context; ViewHolder viewHolder=null;

/** 監聽對象 */
private MyClickListener mListener;
public Videoadapter(ArrayList<VideoInfoModel.DetailBean.VideosBean> list,Context context){
this.mList=list;
this.context=context;
}

public void setOnClickListener(MyClickListener listener) {

mListener = listener;

}


@Override
public int getCount() {
return mList==null?0:mList.size();

}
 
@Override
public Object getItem(int position) {
return mList==null?0:mList.get(position);
}

@Override
public long getItemId(int position) {
return mList==null?0:position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView==null){
viewHolder=new ViewHolder();
//得到佈局
convertView= LayoutInflater.from(context).inflate(R.layout.content_list,null);
//得到控件
viewHolder.img_head= (ImageView) convertView.findViewById(R.id.userhead);
viewHolder.img_video= (ImageView) convertView.findViewById(R.id.img_video);
viewHolder.img_like= (ImageView) convertView.findViewById(R.id.img_like);
viewHolder.txt_uname= (TextView) convertView.findViewById(R.id.username);
viewHolder.img_addreess= (ImageView) convertView.findViewById(R.id.address);
viewHolder.txt_like= (TextView) convertView.findViewById(R.id.txt_like);
viewHolder.txt_address= (TextView) convertView.findViewById(R.id.txt_address);
viewHolder.img_comment= (ImageView) convertView.findViewById(R.id.img_comment);
viewHolder.txt_comment= (TextView) convertView.findViewById(R.id.txt_comment);
viewHolder.btn_attention= (Button) convertView.findViewById(R.id.attention);


//設置頭像的監聽事件
viewHolder.img_head.setOnClickListener(mOnClickListener);

//設置播放視屏的監聽事件
viewHolder.img_video.setOnClickListener(mOnClickListener);

//設置圖片點讚的監聽事件
viewHolder.img_like.setOnClickListener(mOnClickListener);

//設置text的監聽事件
viewHolder.txt_like.setOnClickListener(mOnClickListener);

//設置點擊評論圖片的監聽事件
viewHolder.img_comment.setOnClickListener(mOnClickListener);

//設置點擊評論文字的監聽事件
viewHolder.txt_comment.setOnClickListener(mOnClickListener);

convertView.setTag(viewHolder);

}else{
viewHolder= (ViewHolder) convertView.getTag();
}


//設置postition
viewHolder.img_head.setTag(position);
viewHolder.img_video.setTag(position);
viewHolder.img_like.setTag(position);
viewHolder.txt_like.setTag(position);
viewHolder.img_comment.setTag(position);
viewHolder.txt_comment.setTag(position);


//設置值
viewHolder.img_head.setImageResource(R.mipmap.head);

        ---------------------------初始化ImageLoader--------------------------------

//顯示圖片的配置(使用ImagerLoader必須先初始化，最好放在Application裏面，避免代碼冗餘)

       // 創建默認的ImageLoader配置參數
        ImageLoaderConfiguration configuration = ImageLoaderConfiguration
        .createDefault(this);

        ImageLoader.getInstance().init(configuration);

        ---------------------------初始化ImageLoader--------------------------------

//加載網絡圖片
DisplayImageOptions options = new DisplayImageOptions.Builder()
.cacheInMemory(true).cacheOnDisk(true)
.bitmapConfig(Bitmap.Config.RGB_565).build();

ImageLoader.getInstance().displayImage(mList.get(position).getImgUrl(), viewHolder.img_video, options);


  viewHolder.txt_uname.setText(mList.get(position).getUserID());
viewHolder.img_addreess.setImageResource(R.mipmap.china);
viewHolder.txt_like.setText(mList.get(position).getLikes() + "");
viewHolder.img_comment.setImageResource(R.mipmap.comment);
viewHolder.txt_comment.setText(R.string.comment);
viewHolder.txt_address.setText(R.string.address);

return convertView;

}


class ViewHolder{
private ImageView img_head,img_video,img_like,img_comment,img_addreess;
private TextView txt_uname,txt_like,txt_comment,txt_address;
private Button btn_attention;
}

   //實現點擊事件

private View.OnClickListener mOnClickListener=new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mListener != null) {
int position = (Integer) v.getTag();
switch (v.getId()) {
case R.id.img_video:
mListener.onPlayVideo(Videoadapter.this,v,position);
break;
case R.id.img_like:
mListener.onSetLike(Videoadapter.this, v, position);
break;
case R.id.txt_like:

                       mListener.onSetLike(Videoadapter.this, v, position);                       

                       break;

                case  R.id.txt_like:
                       mListener.onQueryLikeInfo(Videoadapter.this, v, position);
                       break;
                case R.id.img_comment:
                       mListener.onQueryCommentorAddComment(Videoadapter.this, v, position);
                       break;
                case R.id.txt_comment:
                       mListener.onQueryCommentorAddComment(Videoadapter.this,v,position);
                       break;

}
}
}

};

//自定義接口類，方便Activity調用
public  interface  MyClickListener {
    public void  onPlayVideo(BaseAdapter adapter, View view, int position);
    public void  onSetLike(BaseAdapter adapter, View view, int position,Boolean islike);
    public void  onQueryLikeInfo(BaseAdapter adapter, View view, int position);
    public void  onQueryCommentorAddComment(BaseAdapter adapter, View view, int position);

}

4.activity類

public class DiscoverActivity extends Activity {

ArrayList<VideoInfoModel.DetailBean.VideosBean> mList;

Videoadapter adapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.discover_activity);
        initView();
    }

   public void initView(){

       videolist = new ArrayList<VideoInfoModel.DetailBean.VideosBean>();

       adapter = new Videoadapter(videolist, getActivity());
       hotListview.setAdapter(adapter);

}

//實現adapter中的接口調用

  adapter.setOnClickListener(new Videoadapter.OnClickListener() {
            @Override
            public void onPlayVideo(BaseAdapter adapter, View view, int position) {
             
            }

            @Override
            public void onSetLike(BaseAdapter adapter, View view, int position) {
               

            }

            @Override
            public void onQueryLikeInfo(BaseAdapter adapter, View view, int position) {

            }


            @Override
            public void onQueryCommentorAddComment(BaseAdapter adapter, View view, int position) {
  
            }
        });

}
