RecycleView內部的按鈕在點擊時不起作用

Question

我在LinearLayout中創建了一個RecycleView組件，其中還包含其他一些組件。問題是每當我點擊RecycleView組件處的元素時，它應該在控制檯中創建一個TAG，但它不會。我添加了onClickListiner，但它根本沒有反應。

下面是一段代碼，我如何在Activity類和Adapter內創建RecycleView。

活動類：

mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view); 
    mAdapter = new MyAdapter(washLocations, this); 
    mRecyclerView.setAdapter(mAdapter); 
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));  

適配器：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> { 

     private List<WashLocation> washLocations; 
     private LayoutInflater layoutInflater; 

     public MyAdapter(List<WashLocation> washLocations, Context context) { 
      layoutInflater = LayoutInflater.from(context); 
      this.washLocations = washLocations; 
     } 

     @Override 
     public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
      Context context = parent.getContext(); 
      LayoutInflater inflater = LayoutInflater.from(context); 

      // Inflate the custom layout 
      View contactView = inflater.inflate(R.layout.row_recycleview, parent, false); 

      // Return a new holder instance 
      ViewHolder viewHolder = new ViewHolder(context, contactView); 
      return viewHolder; 
     } 

     @Override 
     public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) { 
      // Get the data model based on position 
      WashLocation w = washLocations.get(position); 
      String info = w.getWashName(); 

      // Set item views based on your views and data model 
      TextView textView = holder.info; 
      textView.setText(info); 

      Integer fav = w.getFav(); 
      Boolean favorite = fav == 1 ? true : false; 
      Button addToFav = holder.favorite; 
      addToFav.setText(favorite == true ? "Usuń z ulubionych" : "Dodaj do ulubionych"); 
     } 

     @Override 
     public int getItemCount() { 
      return washLocations.size(); 
     } 


     public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

      private Context context; 
      public TextView info; 
      public Button favorite; 

      public ViewHolder(Context context, View itemView) { 
       super(itemView); 
       itemView.setOnClickListener(this); 
       this.context = context; 
       info = (TextView) itemView.findViewById(R.id.textView); 
       favorite = (Button) itemView.findViewById(R.id.addToFav); 
      } 

      @Override 
      public void onClick(View v) { 
       int position = getAdapterPosition(); // gets item position 
       if (position != RecyclerView.NO_POSITION) { // Check if an item was deleted, but the user clicked it before the UI removed it 
        // We can access the data within the views 
        Toast.makeText(context, info.getText(), Toast.LENGTH_SHORT).show(); 
        Log.d("myTag", "This is my message"); 
       } 
      } 
     } 
    }

我通常使用的onBindViewHolder設置Listener因爲在這個方法中，我們有位置。試着改變你的方法是：

@覆蓋

public void onBindViewHolder(MyAdapter.ViewHolder holder, int position) { 
    // Get the data model based on position 
    final WashLocation w = washLocations.get(position); 
    final String info = w.getWashName(); 

    // Set item views based on your views and data model 
    TextView textView = holder.info; 
    textView.setText(info); 

    Integer fav = w.getFav(); 
    Boolean favorite = fav == 1 ? true : false; 
    Button addToFav = holder.favorite; 
    addToFav.setText(favorite == true ? "Usuń z ulubionych" : "Dodaj do ulubionych"); 
    holder.setOnClickListener(new View.OnClickListener(){ 

     @Override 
     public void onClick(View view){ 
     //Here you have all the data that you want 
     //you can use w variable : w.getWashName(); 
     } 

    }); 
} 

要添加2種不同的監聽器爲每個按鈕：

holder.yourButton1.setOnClickListener(new View.OnClickListener(){ 

     @Override 
     public void onClick(View view){ 
     //Click for button 1 
     } 

    }); 
} 

holder.yourButton2.setOnClickListener(new View.OnClickListener(){ 

     @Override 
     public void onClick(View view){ 
     //Click for button 2 
     } 

    }); 
} 

Answer 2

要設置在的ViewGroup的onClickListener的元素。你應該把它放在按鈕上。

嘗試使用這樣的：

public ViewHolder(Context context, View itemView) { 
    super(itemView); 
    this.context = context; 
    info = (TextView) itemView.findViewById(R.id.textView); 
    favorite = (Button) itemView.findViewById(R.id.addToFav); 
    favorite.setOnClickListener(this); 
} 

Answer 3

改變你這樣的viewholder代碼，

public ViewHolder(Context context, View itemView) { 
       super(itemView); 
       this.context = context; 
       info = (TextView) itemView.findViewById(R.id.textView); 
       favorite = (Button) itemView.findViewById(R.id.addToFav); 
       favorite2 = (Button) itemView.findViewById(R.id.addToFav2); 
       favorite.setOnClickListener(this); 
       favorite2.setOnClickListener(this); 
      } 
     @Override 
     public void onClick(View view){ 
      switch(view.getId()) { 
       case R.id.addToFav : 
         // onclick of button 1 
         break; 
       case R.id.addToFav2 : 
         // onclick of button 1 
         break; 
      } 
     }
