ListView可以正确显示，但是在单击时只能获取最后一个项目 ListView上的搜索功能无法正常工作

问题描述

ListView正确显示了所有内容（标题，艺术家，封面，可绘制内容），但是，当单击时，只会提取最后一项（药片）， 并且搜索功能不能同时过滤歌曲，无法正常运行，希望按歌曲名称进行搜索，为getset方法设置类等也可以正常工作

是Android Studio的初学者，请指导我，非常感谢！

搜索活动：

public class SearchActivity extends AppCompatActivity {

ListView listView;
ArrayList<String> stringArrayList = new ArrayList<>();
Mylistadapter adapter;
//ArrayAdapter<String> adapter;
private SongCollection songCollection = new SongCollection();

String[] mTitle = {
        "Life is Good","Good as Hell","Perfect","Attention","Say You love Me","Sign of the Times","Lemon","Autopilot","First Time","To U","Fractures","Will He","I'm so Grateful","Stay At Home","The A Team","BIGGER","Find U Again","Pills"
};

String[] mArtist = {
        "Drake","Ariana Grande","Ed Sheeran","Joji","Chris brown","Harry Styles","Rihanna","Quinn XCII","Ellie Goulding","Diplo","ILLENIUM","DJ Khaled","Usher","Beyonce","Camila Cabello","Joji"
};

String[] mSongLength = {
        "3.96","2.66","4.39","2.15","2.88","5.68","2.45","3.03","3.23","3.95","5.03","3.37","4.98","3.48","4.31","3.77","2.94","3.12"
};

Integer[] mCoverArt = {
        R.drawable.life_is_good,R.drawable.good_as_hell,R.drawable.perfect,R.drawable.attention,R.drawable.say_you_love_me,R.drawable.sign_of_the_times,R.drawable.lemon,R.drawable.auto_pilot,R.drawable.first_time,R.drawable.to_u,R.drawable.fractures,R.drawable.will_he,R.drawable.im_so_grateful,R.drawable.stay_at_home,R.drawable.the_a_team,R.drawable.bigger,R.drawable.find_u_again,R.drawable.pills
};

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

   // adapter = new ArrayAdapter<>(SearchActivity.this,R.layout.search_item,mTitle,mArtist,mCoverArt,mSongLength);

   adapter = new Mylistadapter(this,mSongLength);

    listView = (ListView)findViewById(R.id.list_view);

    listView.setAdapter(adapter);

    listView.setonItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent,View view,int position,long id) {
            Toast.makeText(getApplicationContext(),adapter.getItem(position),Toast.LENGTH_SHORT).show();
            // Todo Auto-generated method stub
            String title = listView.getItemAtPosition(position).toString();
            Song selectedSong = songCollection.searchByTitle(title);
            AppUtil.popMessage(view.getContext(),"Streaming song: " + selectedSong.getTitle());
            sendDatatoActivity(selectedSong);
        }
    });

** Mylistadapter：**

public class Mylistadapter extends ArrayAdapter<String> {

private final Activity context;
private final String[] mTitle;
private final String[] mArtist;
private final Integer[] mCoverArt;
private final String[] mSongLength;

public Mylistadapter(Activity context,String[] mTitle,String[] mArtist,Integer[] mCoverArt,String[] mSongLength) {
    super(context,mTitle);
    // Todo Auto-generated constructor stub

    this.context = context;
    this.mTitle = mTitle;
    this.mArtist = mArtist;
    this.mCoverArt = mCoverArt;
    this.mSongLength = mSongLength;
}

public View getView(int position,ViewGroup parent) {
    LayoutInflater inflater=context.getLayoutInflater();
    View rowView=inflater.inflate(R.layout.search_item,null,true);

    TextView titleTxt = (TextView) rowView.findViewById(R.id.titleTxt);
    ImageView coverArt = (ImageView) rowView.findViewById(R.id.image);
    TextView artistTxt = (TextView) rowView.findViewById(R.id.titleArtist);
    TextView songLength = (TextView) rowView.findViewById(R.id.txtSongLength);

    titleTxt.setText(mTitle[position]);
    coverArt.setimageResource(mCoverArt[position]);
    artistTxt.setText(mArtist[position]);
    songLength.setText(mSongLength[position]);

    return rowView;

};

}

解决方法

您两次写过setOnItemClickListener，第二个将被覆盖 第一个，所以逻辑上不是您想要的。

仅保留一个并删除另一个。
