Question

我遇到了这个奇怪的问题。我完全按照http://developer.android.com/guide/topics/ui/menus.html#context-menu。我已经在单独的虚拟应用程序上测试它，它工作正常。问题是“窗口已经集中，无视焦点增益：com.android.internal.view.IInputMethodClient$Stub$Proxy@xxxxxx”每当我在按住任何列表项后尝试单击任何上下文菜单项时。永远不会调用“onContextItemSelected”方法。

以下是精简代码：

TaskActivity.java

public class TaskActivity extends Activity{
    private ListView task_list;

    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_layout);//custom xml file of my GUI

        task_list = (ListView) findViewById(R.id.listTasks);

        populateTaskList();//snapped method
        registerForContextMenu(task_list);

     }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
        super.onCreateContextMenu(menu, v, menuInfo);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.context_menu, menu);
        menu.setHeaderTitle("Options");
        Log.v("CBC","HERE2");//It logs, yes

    }

    @Override
    public boolean onContextItemSelected(MenuItem item) {
        Log.v("CBC","HERE1");//Not ever logged this message!
        AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
        switch (item.getItemId()) {
            case R.id.edit_menuitem:
                update_task(info.id);
                return true;
            case R.id.delete_menuitem:
                Log.v("CBC","HERE2");
                delete_task(info.id);
                return true;
        }

        return super.onContextItemSelected(item);

    }
}

<snap irrelevant codes that have played no role in this problem>

activity_layout.xml

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

        android:listSelector="@drawable/list_selectors"
        android:id="@+id/listTasks"/>
</LinearLayout>

task_row.xml

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:background="@drawable/row_selector"
    android:padding="5dip">
    <TextView android:id="@+id/body"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#000000"
        android:textSize="20dip"/>
    <TextView android:id="@+id/mark"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#000000"
        android:textSize="20dip"/>
</LinearLayout>

所以我想知道你是否知道这个奇怪的问题？如果您需要了解更多其他代码，请与我们联系。我向你们保证，他们不相关。

P.S。这是我写的第一个大型应用程序。 P.S.S.我只是在我的Android手机上为我的特殊需求编写这个小应用程序。（Android市场免费的不适合我）。

这解释了为什么你不能一起使用onMenuItemSelected方法和onContextItemSelected。

（Android 2.1）“onContextItemSelected”和“窗口已经聚焦，忽略焦点<snap irrelavant =”“rest =”“>”</snap>
