【问题描述】：

我的项目做巴士票预订所以，当单击recyclierview 中的item 时，将打开巴士座位为50 imageView。我知道如何为一个imageView 添加onClick，但对于我不知道的50 个imageView。我尝试了一些在 stackOverflow 中看到的解决方案。但没有任何工作。您能给我一些关于预订巴士的建议或解决方案吗？

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

我尝试添加此代码并实现 onClick 方法，但它不执行 onClick 内部的操作。

我想将 relative_bus_seat onClick 做的事情添加到这 50 个 imageView 做的事情中。

BusAdapter.java

 public class BusAdapter extends RecyclerView.Adapter<BusAdapter.ViewHolder> {
        private Context context;
        private List<Bus> busList;
        private static String phoneNumber;
        private static final int PERMISSION_CODE = 101;
        private RecyclerView recyclerView;
        private Locale trlocale;


        VoyageAdapterToResultActivityListener voyageAdapterToResultActivityListener;

        public BusAdapter(Context _context, List<Bus> _busList, RecyclerView recyclerView) {
            this.context = _context;
            this.busList = _busList;
            this.recyclerView = recyclerView;
            this.trlocale = new Locale("tr-TR");
            voyageAdapterToResultActivityListener = (VoyageAdapterToResultActivityListener) context;
        }
        public class ViewHolder extends RecyclerView.ViewHolder {
            private TextView tvPrice, text_seat;
            private CardView cardV_row_voyage;
            private RelativeLayout relative_bus_seat;

            // Seats
            private ImageView imageV_seat1, imageV_seat2, imageV_seat3, imageV_seat4, imageV_seat5, imageV_seat6, imageV_seat7,

标签： java android android-recyclerview onclicklistener

【解决方案1】：

首先实现接口OnClickListener到你的ViewHolder

 public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener

然后像这样将点击监听器添加到图像视图中

private ViewHolder(View view) {
                super(view);

      //Your code here after

 imageV_seat1.setOnClickListener(this);
    //add for all the image views


}

并在 Override 方法 onClick 用户切换语句以获得快速执行

public void onClick(View v) {

        switch (v.getId()) {

            case R.id.imageV_seat1:

               // Code Here
                break;

     // add for reset ids

}
}

【讨论】：

【解决方案2】：

为了使代码更小，请使用lambda:

holder.yourImage.setOnClickListener(view -> {
    // do something here
});

【讨论】：

【解决方案3】：

你可以实现 onCLickListener 并在 onClick() 方法中检查它的 imageView，如果它的 imageView 你可以编写你的逻辑。

 public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener

@Override
public void onClick(View view) {
    if(view instanceof ImageView)
   //write your logic here or you can get view.getId method also to write logic for individual imageview
}

【讨论】：

我在调试中试过，但它没有踩到点击。所以，它不起作用。
在此请绑定您的图像视图，例如 imageview.setOnClickListeners(this);

【解决方案4】：

这可以使用一些逻辑游戏来实现。虽然我没有测试它，因为我现在没有可用的 IDE，但代码应该可以工作。

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 
    private Button mButton; 

     private ViewHolder(View view)
    { 
        .....Your existing code

        button1.setOnClickListener(this); 
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);
        .
        .
        .
        button50.setOnClickListener(this);
    } 

    @Override
    public void onClick(View view) 
    { 
        switch (view.getId()) { 
        case R.id.button1: 
        case R.id.button2:
        case R.id.button3:
        .
        .
        .
        case R.id.button50:
            // Do something... by doing this all case will come to this block to execute.
            // Remember, do not use break in any of the above case.
        } 
    } 
}

如果它解决了您的问题，请告诉我。

【解决方案5】：

就那样做吧：-

holder.yourImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // your code hare
            }
        });

【讨论】：

我知道这一点，但我不想为所有 imageView 添加相同的长代码。这不合逻辑。 50 imageView 这是很多代码。
首先，你不需要像这样创建那么多图像。 Recycler 视图可以为您创建所有视图，然后，您可以在 holder.itemView 上设置 onClick 并获取位置然后做您想做的事情。
