ListView項目點擊不工作在Tabhost

Question

我的問題是onItemClickListener無法在列表視圖下的Tabhost。任何listview的onclick事件都不起作用。我曾試過一切。這是我的代碼。請幫我解決一下這個。

我Tabhost文件

<android.support.design.widget.TabLayout 
    android:id="@+id/tabs" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="@color/material_blue_grey_800" 
    app:tabGravity="fill" 
    app:tabIndicatorColor="@color/orange" 
    app:tabMode="fixed" 
    app:tabSelectedTextColor="@color/orange" 
    app:tabTextColor="@color/white"></android.support.design.widget.TabLayout> 

<android.support.v4.view.ViewPager 
    android:id="@+id/viewpager" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

</android.support.v4.view.ViewPager> 

然後主要佈局

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent" > 

    <!--<android.support.v7.widget.RecyclerView--> 
     <!--android:id="@+id/songs_recycleview"--> 
     <!--android:clickable="true"--> 
     <!--android:focusable="true"--> 
     <!--android:layout_width="match_parent"--> 
     <!--android:layout_height="match_parent" />--> 

    <!--<ListView--> 
     <!--android:layout_width="wrap_content"--> 
     <!--android:layout_height="wrap_content"--> 
     <!--android:id="@android:id/list"--> 
     <!--android:layout_alignParentBottom="true"--> 
     <!--android:layout_alignParentRight="true"--> 
     <!--android:layout_alignParentEnd="true"/>--> 

    <ListView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/SongList" 
     android:layout_alignParentBottom="true" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentEnd="true"/> 
</RelativeLayout> 

這裏是列表適配器

public class LazyAdapter extends BaseAdapter { 

private Activity activity; 
private Fragment fragment; 
private AudioListModel[] data; 
private String[] test; 
private static LayoutInflater inflater = null; 
public ImageLoader imageLoader; 

public LazyAdapter(Activity a, String[] d) { 
    activity = a; 
    test = d; 
    inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    imageLoader = new ImageLoader(activity.getApplicationContext()); 
} 
/* 
    private OnItemClickListener mOnItemClickListener; 

    public interface OnItemClickListener { 
     public void onItemClick(View view, int position); 
    } 

    /* 
     public LazyAdapter(Activity a,ArrayList<AudioListModel> d, OnItemClickListener OnItemClickListener) { 
      activity = a; 
      data = d.toArray(new AudioListModel[d.size()]); 
      mOnItemClickListener=OnItemClickListener; 
      inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      imageLoader = new ImageLoader(activity.getApplicationContext()); 
     } 
    */ 
public LazyAdapter(Activity a, AudioListModel[] d) { 
    activity = a; 
    data = d; 
    inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    imageLoader = new ImageLoader(activity.getApplicationContext()); 
} 


public int getCount() { 
    return data.length; 
} 

public Object getItem(int position) { 
    return position; 
} 

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

public View getView(int position, View convertView, ViewGroup parent) { 
    View vi = convertView; 
    if (convertView == null) 
     vi = inflater.inflate(R.layout.rawlistview, null); 
    TextView text = (TextView) vi.findViewById(R.id.songname); 
    //TextView song_path=(TextView)vi.findViewById(R.id.songpath); 
    ImageView image = (ImageView) vi.findViewById(R.id.image); 


    if (test != null) { 
     text.setText(test[position]); 
     imageLoader.DisplayImage(data[position].bitmap, image); 
    } 

    if (data != null) { 
     text.setText(data[position].track); 
     //song_path.setText(data[position].Song_Path); 
     imageLoader.DisplayImage(data[position].bitmap, image); 
    } 


    return vi; 
} 
} 

這裏是主段類

public class PrimaryFragment extends Fragment { 
    RecyclerView rv; 
    LazyAdapter adapter; 
    ListView listView; 
    View rootView; 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     rootView = inflater.inflate(R.layout.primary_layout, container, false); 


     ArrayList<AudioListModel> songsList = SongsManager.GetSongs(); 

     adapter = new LazyAdapter(getActivity(), songsList.toArray(new AudioListModel[songsList.size()])); 
     //rv = (RecyclerView) rootView.findViewById(R.id.songs_recycleview); 

     listView = (ListView) rootView.findViewById(R.id.SongList); 
     LazyAdapter ad = new LazyAdapter(getActivity(), songsList.toArray(new AudioListModel[songsList.size()])); 
       /*LazyAdapter ad = new LazyAdapter(getActivity(), songsList, 
       new LazyAdapter.OnItemClickListener() { 
        @Override 
        public void onItemClick(View view, int position) { 
         Toast.makeText(getActivity(), "this is on click event", Toast.LENGTH_SHORT); 
        } 
       }); 
     */ 
     listView.setItemsCanFocus(false); 
     listView.setAdapter(ad); 
     listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
       Toast.makeText(getActivity(), "this is on click event", Toast.LENGTH_SHORT); 
      } 
     }); 


     return rootView;//inflater.inflate(R.layout.primary_layout, null); 
    } 

請幫我這個。我的點擊是不工作的任何標籤......

Answer 1

嘗試設置您的點擊收聽像這樣：

listview.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?>adapter,View v, int position){ 
Toast.makeText(getActivity(), "this is on click event", Toast.LENGTH_SHORT).show();} }); 

不要讓我知道，如果它改變了你什麼。

編輯：我才意識到這個原因，你想的onClick不工作可能是因爲你不是顯示你的麪包。您需要通過添加.show（）這樣顯示敬酒：

Toast.makeText(getActivity(), "this is on click event", Toast.LENGTH_SHORT).show();
