ListView内の各listItemに対してsetTag（）メソッドを設定する方法

プレーヤー名のリストを保持するMainActivityを作成しました。そのlist_itemをクリックすると、クリックされたアイテムごとにsetTag（）メソッドが必要ですSubActivity.In SubActivity MediaPlayerを実装する方法とそれらのタグを取得する方法。ListView内の各listItemに対してsetTag（）メソッドを設定する方法

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:

スイッチに113個のケースが必要な理由を説明できますか？ – pskink

@pskink私はこのhttp://xyzt.com/plugins/quran/001.mp3のようなurl_pathを持っています。このsetTag（ "001.mp3"）のようなタグを（ "114.mp3"）まで設定し、これらのタグを取得し、これらのタグをSubactivityのURLに連結して祈りをする必要があります。 –

'setTag（String.format（"％03d "、i）+" .mp3 "）'を使うだけです。それは3桁の文字列としてあなたの番号を与えます –

、

 @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; 
       }

@noushadmohammed v.setTag（position）;このように、各項目のタグを簡単に設定できます。ポジションの代わりに、任意のものを自由に設定できます。 –
