ListView setOnItemClickListener不起作用

Question

抱歉我的英文。我花了很多次但我无法解决我的问题。我有listView，我想要设置setOnItemClickListener他。这是我的listView：

 <ListView
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:id = "@+id/listScene"
                    android:clickable="true"
                    android:cacheColorHint="#00000000"
                    android:divider="#adb8c2"
                    android:dividerHeight="1dp"
                    android:scrollingCache="false"
                    android:smoothScrollbar="true"
                    >
                </ListView> 

我的代码

 public void outputListView(ArrayList<String> list) {
        Adapter adapter = new Adapter(getApplicationContext(), R.layout.item, list);
        adapter.notifyDataSetChanged();
        listView.setAdapter(adapter);

        listView.setItemsCanFocus(false);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                Toast.makeText(getApplicationContext(), String.valueOf(position), Toast.LENGTH_SHORT).show();
            }
        });
    }

但是当我点击项目时没有任何反应

            </RelativeLayout>
        </LinearLayout>
    </service.SwipeLayout>

</LinearLayout>

UPD：简单列表视图

activity_main .XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <ListView
        android:id="@+id/listView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:cacheColorHint="#00000000"
        android:divider="#adb8c2"
        android:dividerHeight="1dp"
        android:scrollingCache="false"
        android:smoothScrollbar="true" />


</RelativeLayout>

我的主要

  ArrayList<String> asd = new ArrayList<>();
    for(int i = 0; i < 10; i++) {
        asd.add(String.valueOf(i));
    }

    ListView listView = (ListView) findViewById(R.id.listView);
    Adapter adapter = new Adapter(getApplicationContext(), R.layout.item, asd);
    listView.setAdapter(adapter);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(getBaseContext(), String.valueOf(position), Toast.LENGTH_LONG).show();
        }
    });

和 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">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Large Text"
        android:id="@+id/textView" />
</LinearLayout>

它很好，它的工作当我点击项目列表视图，Toast是显示位置。但我需要使用SwipeLayout然后我更改代码item.xml并添加：

<?xml version="1.0" encoding="utf-8"?>

    android:descendantFocusability="blocksDescendants"

</LinearLayout>

生病了，当我点击项目列表视图时，它无法正常工作。但是当我在清除项目之间进行操作时，它的工作是：

责怪SwipeLayout，代码SwipeLayout：

public class SwipeLayout extends LinearLayout {

    private ViewDragHelper viewDragHelper;
    private View contentView;
    private View actionView;
    private int dragDistance;
    private final double AUTO_OPEN_SPEED_LIMIT = 400.0;
    private int draggedX;

    public SwipeLayout(Context context) {
        this(context, null);
    }

    public SwipeLayout(Context context, AttributeSet attrs) {
        this(context, attrs, -1);
    }

    public SwipeLayout(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        viewDragHelper = ViewDragHelper.create(this, new DragHelperCallback());
    }

    @SuppressLint("MissingSuperCall")
    @Override
    protected void onFinishInflate() {
        contentView = getChildAt(0);
        actionView = getChildAt(1);
        actionView.setVisibility(GONE);
    }

    @Override

我无法删除它，因为我在项目中需要它。我不知道如何解决这种情况

Answer 1

有时ListView点击不起作用。在这种情况下，您可能需要再添加一个属性。

android:descendantFocusability="blocksDescendants"

将此属性添加到您提供ListView元素的XML的最顶层布局。

Answer 2

在ListView删除xml属性android:clickable="true"

这是您的点击事件，而不是将其发送到子视图。

修改

您正在传递getApplicationContext()这是错误的背景。监听器确实有效，但Toast没有在正确的上下文中显示。您需要传递getContext()。但是，由于这是一项活动，您只需传入this。

public void outputListView(ArrayList<String> list) {
    Adapter adapter = new Adapter(this, R.layout.item, list);
    adapter.notifyDataSetChanged();
    listView.setAdapter(adapter);

    listView.setItemsCanFocus(false);
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(this, String.valueOf(position), Toast.LENGTH_SHORT).show();
        }
    });
}
