OnClick在RecyclerView内的TextInputLayout内的EditText中

Question

我的片段中有一个RecyclerView，其中填充了几个TextInputLayout。经过一些研究，我设法将onClickListener设置为TextInputLayout，并且正在运行

BUT

只有在点击TextInputLayout的提示时才会触发onClick事件。当我点击TextInputLayout中的EditText时，我希望它被触发。

代码：

在我的片段中：

adapter.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.i("Logging", "Element: "+rView.getChildAdapterPosition(v));//rView is RecyclerView

            RelativeLayout rel=(RelativeLayout)v;
            TextInputLayout til=(TextInputLayout) rel.getChildAt(0);
            EditText editText=til.getEditText();
            editText.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                }

                @Override
                public void afterTextChanged(Editable s) {
                    Log.i("Logging", "afterTextChanged called");
                }
            });

        }
    });

每个＆＃34;行的XML＆＃34;在RecyclerView中：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/textInputLayout">

    <EditText
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</android.support.design.widget.TextInputLayout>
</RelativeLayout>

这就是我在适配器中设置监听器的方法：

public class IuAdapter extends RecyclerView.Adapter<IuAdapter.ViewHolder> implements View.OnClickListener{

private ArrayList<Model> datos;
private View.OnClickListener listener;

public IuAdapter(ArrayList<Model> datos) {
    this.datos = datos;
}

@Override
public void onClick(View v) {
    if(listener != null){

        listener.onClick(v);
    }else{
        //Some logging
    }

}

public void setOnClickListener(View.OnClickListener listener) {
    this.listener = listener;
}

@Override
public IuAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.rowlayout, parent, false);

        itemView.setOnClickListener(this);
        ViewHolder holder=new ViewHolder(itemView);
        return holder;

}

@Override
public void onBindViewHolder(IuAdapter.ViewHolder holder, int position) {
    Model item=datos.get(position);

    holder.colocarModelo(item);
}

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

public static class ViewHolder extends RecyclerView.ViewHolder{

    private TextInputLayout textInputLayout;

    public ViewHolder(View itemView) {
        super(itemView);
        textInputLayout=(TextInputLayout)itemView.findViewById(R.id.textInputLayout);
    }

    private void colocarModelo(Model model){
        textInputLayout.setHint(model.getHint());
        textInputLayout.getEditText().setText(model.getValor());
    }

}
}

如您所见，我需要在TextInputLayout内的EditText中更改文本后进行一些处理。当我单击提示时，将触发afterTextChanged方法。但是要触发onClick，正如我所说的，我需要单击TextInputLayout的提示，并且当我只是单击里面的EditText时不会触发。我想实现这一点。

我做过什么：

我试图直接在EditText上设置onClickListener，但是它提供了一个异常。

有没有办法达到我想要的目的？

谢谢。

编辑：

根据请求，在TextInputLayout内的EditText上添加onClickListener时出现异常：

为此，我在适配器内的onCreateViewHolder方法中进行了这些更改：

public IuAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        /*View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.rowlayout, parent, false);

        itemView.setOnClickListener(this);
        ViewHolder holder=new ViewHolder(itemView);*/
        RelativeLayout itemView=(RelativeLayout)LayoutInflater.from(parent.getContext())
            .inflate(R.layout.rowlayout, parent, false);
        TextInputLayout til=(TextInputLayout)itemView.getChildAt(0);
        EditText editText=til.getEditText();
        editText.setOnClickListener(this);
        ViewHolder holder=new ViewHolder(itemView);
        return holder;

}

更新：

如果我改变了     ViewHolder holder = new ViewHolder（itemView）; 至     ViewHolder holder = new ViewHolder（til）;

我收到另一种例外：

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Answer 1

问题在于这一行：

TextInputLayout til=(TextInputLayout) rel.getChildAt(0);

在你的片段中。 TextInputLayout不是RelativeLayout的直接子节点。尝试将其更改为：

TextInputLayout til=(TextInputLayout)rel.findViewById(R.id.textInputLayout);

Answer 2

从onCreateViewHolder中删除以下代码：

TextInputLayout til=(TextInputLayout)itemView.getChildAt(0);
EditText editText=til.getEditText();
editText.setOnClickListener(this);

将下面的代码放在公共ViewHolder（查看itemView）中：

super(itemView);
textInputLayout=(TextInputLayout)itemView.findViewById(R.id.textInputLayout);
EditText text=(EditText)itemView.findViewById(R.id.text);
text.setOnClickListener(this);

在OnClickListener类

中实施ViewHolder接口

在布局文件中放置此行EditText：

android:focusable="true"

当您单击EditText时，它调用了FocusChangeListener，然后再次单击，然后OnClickEvent被触发。这就是设置android:focusable="true"。

的原因

Answer 3

试试这个

    public static class ViewHolder extends RecyclerView.ViewHolder{

        private TextInputLayout textInputLayout;
        private EditText editText;

        public ViewHolder(View itemView) {
            super(itemView);
            textInputLayout=(TextInputLayout)itemView.findViewById(R.id.textInputLayout);
            editText=(EditText)itemView.findViewById(R.id.text);
            editText.addTextChangedListener(new TextWatcher() {
                @Override
                public void beforeTextChanged(CharSequence s, int start, int count, int after) {

                }

                @Override
                public void onTextChanged(CharSequence s, int start, int before, int count) {

                }

                @Override
                public void afterTextChanged(Editable s) {

                }
            });


        }

        private void colocarModelo(Model model){
            textInputLayout.setHint(model.getHint());
            textInputLayout.getEditText().setText(model.getValor());
        }

    }

Answer 4

创建itemview时，不应在onCreateViewHolder方法中将父param传递给inflate方法，将第二个param设置为null

public IuAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
...
    RelativeLayout itemView= (RelativeLayout)LayoutInflater.from(parent.getContext())
        .inflate(R.layout.rowlayout, parent, false);

使用

    RelativeLayout itemView= (RelativeLayout)LayoutInflater.from(parent.getContext())
        .inflate(R.layout.rowlayout, null, false);

Answer 5

你可以尝试

吗？

@Override
public IuAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.rowlayout, parent, false);
        EditText text=(EditText)itemView.findViewById(R.id.text);
       text.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {


        }
    });
        return holder;

}
