我创建了一个包含播放器名称列表的MainActivity。当我点击那个list_item时，需要为每个被点击的项目设置setTag（）方法，并且应该调用SubActivity.In SubActivity如何实现MediaPlayer以及如何获取那些标签。
MainActivity：
public class MainActivity extends AppCompatActivity {
String[] audioTitels;
ListView listView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Resources res = getResources();
audioTitels = res.getStringArray(R.array.audio_list);
listView = (ListView) findViewById(R.id.listView);
AudioAdapter audioAdapter = new AudioAdapter(this,audioTitels);
listView.setAdapter(audioAdapter);
listView.setOnItemClickListener(new
AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
switch (i){
case 0 :
System.out.println("Value of song0 :"+ audioTitels[i]);
Toast.makeText(MainActivity.this,"Song to Play",Toast.LENGTH_LONG).show();
break;
case 1:
Toast.makeText(MainActivity.this,"Song to Play",Toast.LENGTH_LONG).show();

答案 0 :(得分：0)
您可以在getView中执行click事件，
@Override
public View getView(int position, View convertView, ViewGroup
parent) {
View row = convertView;
if(row == null){
LayoutInflater layoutInflater = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row =
layoutInflater.inflate(R.layout.single_audio,parent,false);
}
//getting refernce to the textview
TextView myTitle = (TextView)
row.findViewById(R.id.audioText);
myTitle.setText(myTitles[position]);
myTitle.setAnimation(AnimationUtils.loadAnimation(context,R.anim.list_animation));
// ========= Permform Click Event ===================
row.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
v.setTag((position+1)+".mp3");
// You can do your code here ....
}
});
return row;
}
