android - 使用 Spinner 处理 GridView 单元格中的点击事件

Question

我使用以下代码捕捉对 gridview 项目单元格的点击。这很好用。

grid_main.setAdapter(new ImageAdapter(this));
grid_main.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
    }
});

然后我在 gridview 单元格内添加了一个 Spinner 对象。现在，我可以单击 Spinner 对象，但包含的 gridview 单元格不再响应单击。我假设 Spinner 监听器正在替换 gridview 监听器。 gridview 和 spinner 监听器都可以单独工作，但在一起时我遇到了问题。我需要能够同时点击两者。下面是微调器代码:

final Spinner spinner = (Spinner) v.findViewById(R.id.driver_list);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(DispatchMonitorCalls.this,
android.R.layout.simple_spinner_item, driverlist_name);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

spinner.setOnItemSelectedListener(new OnItemSelectedListener() { 
    public void onItemSelected(AdapterView<?> arg0, View arg1,
    int arg2, long arg3) {
    }
@Override
public void onNothingSelected(AdapterView<?> arg0) {
    // TODO Auto-generated method stub
} 
});

下面是布局xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/driverrow"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_gravity="left"
    android:gravity="left" >

    <TextView
        android:id="@+id/row_locationtype"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_marginLeft="10dip"
        android:layout_alignParentTop="true"        
        android:text="Empty"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <TextView
        android:id="@+id/row_timestamp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/row_locationtype"        
        android:layout_below="@+id/row_locationtype"
        android:text="Empty"
        android:textAppearance="?android:attr/textAppearanceSmall" />

    <TextView
        android:id="@+id/row_status"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/row_locationtype"        
        android:layout_below="@+id/row_timestamp"
        android:text="Empty"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:textColor="#ff8080" />

    <Spinner
        android:id="@+id/driver_list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/row_locationtype"        
        android:layout_below="@+id/row_status"
        android:paddingBottom="20dp" />

</RelativeLayout>

提前谢谢你。

您需要在您的相关布局上调用“blocksDecendants”，因为微调器是可点击的，它会窃取您 View 的焦点，因此您的“点击事件”会飞走

试试这个:

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/driverrow"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_gravity="left"
    android:descendantFocusability="blocksDescendants" //<-- add this line, and your click event will be responded 

android:gravity="left" >

<TextView
    android:id="@+id/row_locationtype"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_marginLeft="10dip"
    android:layout_alignParentTop="true"        
    android:text="Empty"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<TextView
    android:id="@+id/row_timestamp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/row_locationtype"        
    android:layout_below="@+id/row_locationtype"
    android:text="Empty"
    android:textAppearance="?android:attr/textAppearanceSmall" />

<TextView
    android:id="@+id/row_status"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/row_locationtype"        
    android:layout_below="@+id/row_timestamp"
    android:text="Empty"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:textColor="#ff8080" />

<Spinner
    android:id="@+id/driver_list"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@+id/row_locationtype"        
    android:layout_below="@+id/row_status"
    android:paddingBottom="20dp" />
