列表视图中的单击侦听器在底部工作表中不起作用

Question

我有一个listview，它位于Bottomsheet中。一切都很好。但是现在我已经更改了listview项目的设计现在我有了Listview，它有两个文本视图和一个图像视图，将作为删除按钮处理。

list_item.xml

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

    <LinearLayout
        android:id="@+id/llContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
         >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">
            <TextView
                android:id="@+id/tvLocationName"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text=""
                android:maxLines="1"
                android:singleLine="true"
                android:textColor="@color/primary_text"
                android:layout_gravity="center_vertical|left"
                android:gravity="left"
                android:textAppearance="?android:textAppearanceSmall"
                android:paddingLeft="15dp"/>

            <android.support.v7.widget.AppCompatImageView
                android:id="@+id/ivDelete"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:paddingLeft="10dp"
                android:paddingRight="10dp"
                android:paddingTop="5dp"
                android:paddingBottom="5dp"
                app:srcCompat="@drawable/wrapped_ic_clear"
                android:focusable="false"
                />
        </LinearLayout>


        <TextView
            android:id="@+id/tvLocationAddress"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text=""
            android:maxLines="1"
            android:singleLine="true"
            android:textColor="@color/secondary_text"
            android:layout_gravity="center_vertical|left"
            android:gravity="left"
            android:textSize="12sp"
            android:paddingLeft="15dp"/>



    </LinearLayout>

</RelativeLayout>

在getview里面我正在做这个

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


    final LocationServiceModel mModel = getItem(position);

    //Check if an existing view is being reused, otherwise inflate the view
    final ViewHolder viewHolder; // view lookup cache stored in tag
    if (convertView == null) {
        //If there's no view to re-use, inflate a brand new view for row
        viewHolder = new ViewHolder();
        LayoutInflater inflater = LayoutInflater.from(mContext);
        convertView = inflater.inflate(resourceLayout, parent, false);

        viewHolder.tvLocationName = (TextView) convertView.findViewById(R.id.tvLocationName);
        viewHolder.tvLocationAddress = (TextView) convertView.findViewById(R.id.tvLocationAddress);

        viewHolder.ivDelete = (AppCompatImageView) convertView.findViewById(R.id.ivDelete);
        viewHolder.llContainer= (LinearLayout) convertView.findViewById(R.id.llContainer);

        convertView.setTag(viewHolder);
    } else {
        // View is being recycled, retrieve the viewHolder object from tag
        viewHolder = (ViewHolder) convertView.getTag();
    }






    viewHolder.ivDelete.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            listener.onDeleteFavoriteStore(mModel);
        }
    });

    viewHolder.llContainer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            listener.onFavoriteStoreItemClick(mModel);
        }
    });

    viewHolder.tvLocationName.setText(mModel.getFriendlyName() + "");

    if(mModel.getAddress()!=null && !mModel.getAddress().equalsIgnoreCase("null")) {
        viewHolder.tvLocationAddress.setText(mModel.getAddress());
    }else {
        viewHolder.tvLocationAddress.setText("");
    }


    return convertView;
}




private static class ViewHolder {
    TextView tvLocationName, tvLocationAddress;
    AppCompatImageView ivDelete;

    LinearLayout llContainer;
}

listview

 <ListView
    android:id="@+id/lvLocations"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    android:minHeight="200dp"
   />

  

但我的点击事件无效。

我尝试过使用SO的一些解决方案，即使用以下属性

• 机器人：可聚焦=＆＃34;假＆＃34;
• 机器人：descendantFocusability =＆＃34; blocksDescendants＆＃34;

但他们没有为我工作。

我想要的是什么：

  

我想用基本上有2个点击监听器的项目制作一个列表视图。

1. 删除事件＆gt;当用户点击图像视图（在项目中右对齐）
时
2. 编辑活动＆gt;当用户单击除用于启动Delete事件的图像视图之外的项目中的任何位置。

Answer 1

我认为，正如您所说，您已经实施了Motion / Touch活动，我会为您提供一些提示。

我担心您在实施中消耗触摸事件。你需要返回false。这样其他工作就可以继续下去了。

例如：

@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
return false;
}

请检查，如果你犯了这个错误的回复真实。这将表明您已经消耗了该事件，并且没有进一步的操作。删除它并返回false。

Answer 2

首先，使ListView的父级布局可点击并将其焦点设置为true

android:clickable="true"
android:focusable="true"

botton_sheet_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/dashBoard_bottomSheetContainer_id"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bottom_sheet_background"
    android:clickable="true"
    android:focusable="true"
    android:padding="10dp"
   app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">

    <ListView
        android:id="@+id/myListView_id"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</LinearLayout>

在那之后，使listview行布局可点击和可聚焦，并删除imageview可点击和可聚焦。

row_layout.xml

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

    <LinearLayout
        android:id="@+id/llContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:clickable="true"
        android:focusable="true">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal">
            <TextView
                android:id="@+id/tvLocationName"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:text=""
                android:maxLines="1"
                android:singleLine="true"
                android:textColor="@color/primary_text"
                android:layout_gravity="center_vertical|left"
                android:gravity="left"
                android:textAppearance="?android:textAppearanceSmall"
                android:paddingLeft="15dp"/>

            <android.support.v7.widget.AppCompatImageView
                android:id="@+id/ivDelete"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:paddingLeft="10dp"
                android:paddingRight="10dp"
                android:paddingTop="5dp"
                android:paddingBottom="5dp"
                app:srcCompat="@drawable/wrapped_ic_clear"
                android:clickable="true"
                android:focusable="true"/>
        </LinearLayout>


        <TextView
            android:id="@+id/tvLocationAddress"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text=""
            android:maxLines="1"
            android:singleLine="true"
            android:textColor="@color/secondary_text"
            android:layout_gravity="center_vertical|left"
            android:gravity="left"
            android:textSize="12sp"
            android:paddingLeft="15dp"/>
    </LinearLayout>

</RelativeLayout>

在适配器中执行此操作

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


    final LocationServiceModel mModel = getItem(position);

    //Check if an existing view is being reused, otherwise inflate the view
    final ViewHolder viewHolder; // view lookup cache stored in tag
    if (convertView == null) {
        //If there's no view to re-use, inflate a brand new view for row
        viewHolder = new ViewHolder();
        LayoutInflater inflater = LayoutInflater.from(mContext);
        convertView = inflater.inflate(resourceLayout, parent, false);

        viewHolder.tvLocationName = (TextView) convertView.findViewById(R.id.tvLocationName);
        viewHolder.tvLocationAddress = (TextView) convertView.findViewById(R.id.tvLocationAddress);

        viewHolder.ivDelete = (AppCompatImageView) convertView.findViewById(R.id.ivDelete);
        viewHolder.llContainer= (LinearLayout) convertView.findViewById(R.id.llContainer);

        convertView.setTag(viewHolder);
    } else {
        // View is being recycled, retrieve the viewHolder object from tag
        viewHolder = (ViewHolder) convertView.getTag();
    }






    viewHolder.ivDelete.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ((ListView) parent).performItemClick(v, position, 0);
        }
    });

    viewHolder.llContainer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ((ListView) parent).performItemClick(v, position, 0);
        }
    });

    viewHolder.tvLocationName.setText(mModel.getFriendlyName() + "");

    if(mModel.getAddress()!=null && !mModel.getAddress().equalsIgnoreCase("null")) {
        viewHolder.tvLocationAddress.setText(mModel.getAddress());
    }else {
        viewHolder.tvLocationAddress.setText("");
    }


    return convertView;
}




private static class ViewHolder {
    TextView tvLocationName, tvLocationAddress;
    AppCompatImageView ivDelete;

    LinearLayout llContainer;
}

在活动中的ListViw上添加onItemClickListener。

ListView listView = findViewById(R.id.lvLocations);

///set your adaper here

listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){
   @Override
   public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    long viewId = view.getId();

    if (viewId == R.id.ivDelete) {
        Toast.makeText(MainActivity.this, "Delete Item", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(MainActivity.this, "Edit item", Toast.LENGTH_SHORT).show();
    }
}
});

实际上，performItemClick（）函数将触发listView中的onItemClick（）函数。
