自定義列表視圖

設置onClicks我試圖作出在ListView項目的onlcicklistener，但我不知道從哪裏開始。我嘗試了一些東西，但都沒有工作。下面是類代碼：自定義列表視圖

public class Primary_Weapons extends Activity { 
    private ListView listView1; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.we_primary_list); 

     Weapon weather_data[] = new Weapon[] 
     { 
      new Weapon(R.drawable.we_braton, "Braton"), 
      new Weapon(R.drawable.we_braton_prime, "Braton Prime"), 
      new Weapon(R.drawable.we_braton_vandal, "Braton Vandal"), 
      new Weapon(R.drawable.we_braton, "MK1-Braton"), 
      new Weapon(R.drawable.we_boltor, "Boltor") 
     }; 

     WeaponAdapter adapter = new WeaponAdapter(this, 
       R.layout.listview_item_row, weather_data); 


     listView1 = (ListView)findViewById(R.id.listView1); 

     View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null); 
     listView1.addHeaderView(header); 

     listView1.setAdapter(adapter); 
    } 
}

當用戶點擊一個項目，它的文本將定義一個字符串，那麼該字符串將在另一種方法來使用。例如，如果選擇「Braton總理」，這將設置一個字符串「Braton總理」，那麼將被用來做其他的東西

編輯：適配器代碼：

public class WeaponAdapter extends ArrayAdapter<Weapon>{ 

    Context context; 
    int layoutResourceId;  
    Weapon data[] = null; 

    public WeaponAdapter(Context context, int layoutResourceId, Weapon[] data) { 
     super(context, layoutResourceId, data); 
     this.layoutResourceId = layoutResourceId; 
     this.context = context; 
     this.data = data; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View row = convertView; 
     WeatherHolder holder = null; 

     if(row == null) 
     { 
      LayoutInflater inflater = ((Activity)context).getLayoutInflater(); 
      row = inflater.inflate(layoutResourceId, parent, false); 

      holder = new WeatherHolder(); 
      holder.imgIcon = (ImageView)row.findViewById(R.id.imgIcon); 
      holder.txtTitle = (TextView)row.findViewById(R.id.txtTitle); 

      row.setTag(holder); 
     } 
     else 
     { 
      holder = (WeatherHolder)row.getTag(); 
     } 

     Weapon weather = data[position]; 
     holder.txtTitle.setText(weather.title); 
     holder.imgIcon.setImageResource(weather.icon); 

     return row; 
    } 

    static class WeatherHolder 
    { 
     ImageView imgIcon; 
     TextView txtTitle; 
    } 
}

編輯3：基本上我想在ListView的每個項目做不同的事情

只需設置一個監聽你的列表視圖。

listView1.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View view, 
      int position, long id) { 

     //Something like... 
     Weapon weapon = adapter.getItem(position); 
     textField.setText(weapon.getName()); 
     //... 
    } 
});

感謝這一點，但如何將我去的問題中提及設置字符串？ – cw1998

@ cwilkinson1998你能證明你的適配器代碼？ – Raghunandan

@Raghunandan如果您編輯自己的帖子，請做正確！ – Benoit

使用setOnItemClickListener

listView1.setOnItemClickListener(new OnItemClickListener() 
    { 

public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, 
       long arg3) { 

    }    
    });
