注册按钮运行良好，但调试器不会运行到setOnItemClickListener onItemClick。如果您单击某个项目，则应启动用于编辑该记录的活动。

activity_Cardmanager.html

<LinearLayout 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:orientation="vertical" >

<ListView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"

row.xml 我为文本字段添加了clickable项目。我认为这不是真正的必要条件。

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

<TextView
    android:id="@+id/tv_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:clickable="true"
    android:width="100dp" />

<TextView
    android:id="@+id/tv_detail"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="20dp"
    android:width="100dp" />

<CheckBox
    android:id="@+id/tv_active"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginLeft="20dp" />

</LinearLayout>

Answer 1

您的列表视图项目中有可聚焦/可点击的项目 - 复选框。

选项1 - 将android:descendantFocusability="blocksDescendants"标记设置为ListView，您应该触发onItemClickListener。

选项2 - 在您的适配器中，您可以在整个列表视图项对象上设置onClickListener，并从那里处理它。

Answer 2

我的解决方案问题出在row.xml上

再次超过X：

row.xml

<LinearLayout
android:clickable="true" (removed)

<TextView
    android:id="@+id/tv_title"
    android:onClick="Title" (added)
    android:clickable="true" (added)
    android:focusable="true" (added)

在我的Activity_cardmanager上，我在nameList.setAdapter ...

之后插入了以下代码

nameList.setClickable(true);            // 2015-04-14
nameList.setFocusable(true);            // 2015-04-14
nameList.setItemsCanFocus(true);        // 2015-04-14
setViewItemListener();

。。

    public void setViewItemListener() {
        nameList.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> tobjParent, View tobjView, int tintPosition, long tlngid) {
                Bundle passdata = new Bundle();
//              Cursor listCursor = (Cursor) tobjParent.getItemAtPosition(tintPosition);
                Cursor listCursor = (Cursor) nameList.getItemAtPosition(tintPosition);  //2015-04-15
                int nameId = listCursor.getInt(listCursor
                        .getColumnIndex(MindXopenHelper.KEY_ID));
                passdata.putInt(MindXopenHelper.KEY_ID, nameId);
                Intent passIntent = new Intent(Activity_cardmanager.this,
                        Activity_edit_mindxtables.class);
                Toast.makeText(getApplicationContext(),
                 Integer.toString(nameId), Toast.LENGTH_LONG).show();

                passIntent.putExtras(passdata);
                startActivity(passIntent);
            }
        });     
    }

returnValue为true，但这是另一个故事。

OnItemClickListener没有触发
