如何检测自定义列表中单击哪个按钮和哪个位置

Question

我正在使用自定义列表视图，其中每个项目都有两个按钮。以下是我的项目xml。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:orientation="horizontal" 
    android:weightSum="10"> 

      <Button 
       android:id="@+id/btn_sound" 
       android:layout_width="0dp" 
       android:layout_height="fill_parent" 
       android:layout_gravity="left" 
       android:layout_marginLeft="3dp" 
       android:layout_marginTop="3dp" 
       android:layout_marginBottom="3dp" 
       android:layout_marginRight="0dp" 
       android:background="@drawable/btn_background" 
       android:gravity="left|center_vertical" 
       android:paddingLeft="10dp" 
       android:text="Sound Name" 
       android:textSize="20sp" 
       android:textStyle="bold" 
       android:layout_weight="7" /> 

      <ImageButton 
       android:id="@+id/ib_info" 
       android:layout_width="0dp" 
       android:layout_height="fill_parent" 
       android:layout_gravity="right" 
       android:gravity="left|center_vertical" 
       android:layout_marginLeft="0dp" 
       android:layout_marginTop="3dp" 
       android:layout_marginBottom="3dp" 
       android:layout_marginRight="3dp" 
       android:layout_weight="3" 
       android:src="@drawable/btn_info_source" 
       android:background="@drawable/btn_info_background" /> 

</LinearLayout> 

和以下是我使用的Addapter。

public class CustomListAdapter extends BaseAdapter implements OnClickListener { 
    Context mContext; 
    String[] mArrayList; 

    public CustomListAdapter(Context context, String[] SoundNames) { 
     this.mContext = context; 
     this.mArrayList = SoundNames; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     Holder holder; 
     if (convertView == null) { 
      holder = new Holder(); 
      LayoutInflater inflater1 = (LayoutInflater) this.mContext 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

      convertView = inflater1.inflate(R.layout.list_item, null); 
      holder.btn_sound = (Button) convertView.findViewById(R.id.btn_sound); 
      holder.ib_info = (ImageButton) convertView.findViewById(R.id.ib_info); 
      convertView.setTag(holder); 
     } else { 
      holder = (Holder) convertView.getTag(); 
     } 

     holder.btn_sound.setText(mArrayList[position]); 
     //holder.btn_sound.setOnClickListener(this); 
     return convertView; 
    } 

    private static class Holder { 

     Button btn_sound; 
     ImageButton ib_info; 
    } 

    @Override 
    public int getCount() { 
     return mArrayList.length; 
    } 

    @Override 
    public Object getItem(int position) { 
     return mArrayList[position]; 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

} 

我在下面的代码中设置列表视图。

public class SectionFragment extends Fragment { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     View rootView; 
     ListView mListView; 
     Bundle args = getArguments(); 
     int currentView = args.getInt(Constants.ARG_SECTION_NUMBER) - 2; 

     if (currentView == 0) { 
      rootView = inflater.inflate(R.layout.deer, container, false); 
      //mListView = (ListView) rootView.findViewById(R.id.listView_deer); 
      CustomListAdapter mListAdapter = new CustomListAdapter(MainActivity.appContext, Constants.deer_Sound_Names); 
      //mListView.setAdapter(mListAdapter); 
      ((AdapterView<ListAdapter>) rootView.findViewById(R.id.listView_deer)).setAdapter(mListAdapter); 
      ((AdapterView<ListAdapter>) rootView.findViewById(R.id.listView_deer)).setOnItemClickListener(mListner); 


     } else if (currentView == 1) { 
      rootView = inflater.inflate(R.layout.guide_layout, container, false); 
      Toast.makeText(MainActivity.appContext, "Loading Guide...", Toast.LENGTH_LONG).show(); 
      WebView guideViewer = (WebView) rootView.findViewById(R.id.webView_guide); 
      guideViewer.loadUrl("file:///android_asset/deer_html/guide.htm"); 

     } else { 

      rootView = inflater.inflate(R.layout.activity_main, container, 
        false); 
     } 
     return rootView; 
    } 
    OnItemClickListener mListner = new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position,long id) { 
      Log.d("HFI","Item Clicked: "+Constants.deer_Sound_Index[position]); 
      switch (view.getId()) { 
      case R.id.btn_sound: 
       Log.d("HFI","Sound: "+Constants.deer_Sound_Index[position]); 
       break; 
      case R.id.ib_info: 
       Log.d("HFI","Info: "+Constants.deer_Sound_Index[position]); 
       break; 
      default: 
       break; 
      }   
     } 
    }; 

} 

问题：自定义列表视图不被registred与setOnItemClickListener(mListner); Actualy我想要检测哪个按钮，并在该位置已经被点击了SectionFragment类。

Answer 1

我添加的onClick中对我的作品的getView。 代码：

public View getView(final int position, View convertView, ViewGroup parent) { 
     Holder holder; 
     if (convertView == null) { 
      holder = new Holder(); 
      LayoutInflater inflater1 = (LayoutInflater) this.mContext 
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = inflater1.inflate(R.layout.list_item, null); 
      holder.btn_sound = (Button) convertView.findViewById(R.id.btn_sound); 
      holder.ib_info = (ImageButton) convertView.findViewById(R.id.ib_info); 
      convertView.setTag(holder); 
     } else { 
      holder = (Holder) convertView.getTag(); 
     } 

     holder.btn_sound.setText(mArrayList[position]); 

     holder.btn_sound.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       //Sound Button Click 
      } 
     }); 
     holder.ib_info.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       //info Button Click 
      } 
     }); 
     return convertView; 
    } 

Answer 2

这将工作

@SuppressWarnings("unchecked") 
public class ViewHolder 
{ 

private static final String TAG = "View Holder"; 

public static <T extends View> T get(View view, int id) 
{ 
    SparseArray<View> viewHolder = (SparseArray<View>) view.getTag(); 
    if (viewHolder == null) 
    { 
     viewHolder = new SparseArray<View>(); 
     view.setTag(viewHolder); 
    } 
    View childView = viewHolder.get(id); 
    if (childView == null) 
    { 
     childView = view.findViewById(id); 
     viewHolder.put(id, childView); 
    } 
    return (T) childView; 
} 

public static <T extends View> T get(View view, int id, int position) 
{ 
    SparseArray<View> viewHolder = (SparseArray<View>) view.getTag(); 
    if (viewHolder == null) 
    { 
     viewHolder = new SparseArray<View>(); 
     view.setTag(viewHolder); 
    } 
    View childView = viewHolder.get(id); 

    if (childView == null) 
    { 
     childView = view.findViewById(id); 
     viewHolder.put(id, childView); 
    } 
    childView.setTag(position); 
    return (T) childView; 
} 
} 

和getView

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 

    if (convertView == null) { 

     LayoutInflater inflater1 = (LayoutInflater) this.mContext 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     convertView = inflater1.inflate(R.layout.list_item, null); 

    } 
    Button btn_sound = ViewHolder.get(findViewById(R.id.btn_sound), position); 
     ImageButton ib_info = ViewHolder.get(findViewById(R.id.ib_info)); 


    btn_sound.setText(mArrayList[position]); 
    btn_sound.setOnClickListener(this); 
    return convertView; 
} 

@Override 
    public void onClick(View v) { 
     int position = (Integer)v.getTag(); 
     // do whatever you want 
    }
