Item 中的 Listview 单击侦听器在底部工作表中不起作用

[英]Listview click listener inside Item is not working in bottom sheet

我有一个列表视图,它位于Bottomsheet 内。 一切正常。 但是现在我已经改变了 listview Item 的设计现在我有 Listview 有两个文本视图和一个图像视图,它们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"

        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: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:focusable="false"
                />
        </LinearLayout>


        <TextView
            android:id="@+id/tvLocationAddress"
            android:layout_width="match_parent"

            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;
}

列表视图

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

但是我的点击事件不起作用。

我尝试使用 SO 的一些解决方案,即使用以下属性

  • 机器人:焦点=“假”
  • android:descendantFocusability="blocksDescendants"

但他们都没有为我工作。

我想要的是:

我想用基本上有 2 个点击侦听器的项目制作一个列表视图。

  1. 删除事件> 当用户单击图像视图时(在项目中右对齐)
  2. 编辑事件> 当用户单击项目中的任意位置时,将用于启动删除事件的图像视图除外。

我想正如你所说的,你有 Motion/Touch 事件的实现,我有一些提示给你。

我担心你在你的实现中消耗了触摸事件。 你需要返回false。 以便其他工作继续进行。

例如:

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

请检查,如果您犯了返回 true 的错误。 这将表明您已经消费了该事件并且没有进一步的操作要进行。 删除它并返回false。

首先,使ListView的父布局可点击且可聚焦为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>

之后,使 listview rowlayout 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>

在适配器中这样做,

@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;
}

在您的活动中的 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() 函数会触发 listView 中的 onItemClick() 函数。
