Question

我更新了布局，用Buttons instaed替换了ImageViews，当我使用带有ImageViews的旧布局时，Listview OnCLick监听器现在不能正常工作。如果需要进一步格式化，请告诉我，任何帮助都将被解决。

活动中的监听器：

lvItem.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Intent intent = new Intent(MainActivity.this, ItemDetailsActivity.class);
        intent.putExtra("Position", position);
        startActivity(intent);
    }
});

list_item.xml：

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

    <android.support.v7.widget.CardView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dp">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical"
            android:padding="16dp">

            <TextView
                android:id="@+id/ItemNametv"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Item : "
                android:textSize="20sp"
                android:layout_marginBottom="8dp"/>

            <TextView
                android:id="@+id/qtytv"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Qty : "
                android:layout_marginBottom="8dp"/>

            <View
                android:layout_width="fill_parent"

            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:orientation="horizontal">

                <Button
                    android:id="@+id/EditItem"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="Edit"
                    android:minWidth="0dp"

                    android:minHeight="0dp"
                    style="@style/Widget.AppCompat.Button.Borderless"/>

            </LinearLayout>

        </LinearLayout>

    </android.support.v7.widget.CardView>

ItemDetailsAdapter.java：

public class ItemDetailsAdapter extends BaseAdapter {

    public ItemDetailsAdapter(Context context, ArrayList<Item> arrayListItem) {

    @Override
    public int getCount() {

        return arrayListItem.get(position);

Answer 1

存在观点冲突的问题，即观点可能会被其他人重叠，所以添加

您的父级布局和列表项上的

android:focusable="false"以及您要为其处理点击事件的所有视图，对于他们，mRecyclerView.computeHorizontalScrollOffset(); mRecyclerView.computeVerticalScrollOffset();在此处添加此按钮...

Answer 2

尝试这个

data["eventType"] = ["*ABC"]

Answer 3

第1步：在 list_item.xml 中，将android:descendantFocusability="blocksDescendants"添加到您的根Linearlayout。
第2步：在 list_item.xml 中，将android: focusable="false"添加到android.support.v7.widget.CardView

注意：如果android:clickable="true"中有android.support.v7.widget.CardView则将其删除。
