如何設置setTag（）方法爲每個的listItem ListView中

我創建保存玩家列表中選擇一個MainActivity names.When我點擊到LIST_ITEM需要setTag（）方法爲每個點擊的項目，那應該叫SubActivity.In SubActivity如何實現MediaPlayer以及如何獲取這些Tag。如何設置setTag（）方法爲每個的listItem ListView中

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(); 
         break; 
        case 2: 

         Toast.makeText(MainActivity.this,"Song to Play",Toast.LENGTH_LONG).show(); 
         break; 
        case 3: 

         Toast.makeText(MainActivity.this,"Song to Play",Toast.LENGTH_LONG).show(); 
         break; 
        case 4: 

         Toast.makeText(MainActivity.this,"Song to Play",Toast.LENGTH_LONG).show(); 
         break;

你能解釋一下爲什麼你在你的交換機需要113'cases'？ – pskink

@pskink我有這樣的url_path http://xyzt.com/plugins/quran/001.mp3。我需要設置標籤這樣setTag（「001.mp3」）到（「114.mp3」），並讓這些標籤並連接這些標籤的URL的子活動發揮祈禱。 –

只需使用'setTag（String.format（「％03d」，i）+「.mp3」）'。它會給你你的電話號碼的3位數字符串 –

您可以在getView這樣執行的單擊事件，

 @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; 
       }
