尝试使用此代码。

lv1.setOnItemClickListener(new OnItemClickListener() {     ![enter image description here][2]
     @Override
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
          String value = lv1.getItemAtPosition(position).toString();
               //display value here 
         }
});

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    int pos = parent.getPositionForView(view);
    Toast.makeText(this,pos + "",Toast.LENGTH_SHORT).show();
}

如果您的ListView项目是使用ArrayAdapter（有希望）从数组单词填充并使用类 Word 实现的，并使用此构造函数：

public class Word {
    private String mValueA;
    /** Image resource ID for the word */
    private int mAudioResourceId;

    /*
    * Create a new Word object.
    */

    public Word(String valueA, int audioResourceId) {
        mValueA = valueA;
        mAudioResourceId = audioResourceId;
    }

   /*
    * Get the default translation of the word
     */
    public String getValueA() {
        return mValueA;
    }

    /**
     * Return the audio resource ID of the word.
     **/

    public int getAudioResourceId() {
        return mAudioResourceId;
    }    
}

然后您可以设置 setOnItemClickListener 来访问点击的项目，例如播放此列表项目的数组中定义的音频。

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
        //like this:
        Word word = words.get(position);
        //and use this position to play the audio from the array
        //corresponding to its item
        mMediaPlayer = MediaPlayer.create(SomeActivity.this, word.getAudioResourceId());
        mMediaPlayer.start();
    }
});

public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
    int pos = (int) adapterView.getPositionForView(view);
    Toast.makeText(MainActivity.this, pos, Toast.LENGTH_SHORT).show();
