Question

我试图在我的Android + HoloEverywhere应用程序上实现抽屉菜单。

我使用http://developer.android.com/training/implementing-navigation/nav-drawer.html中描述的方法开始使用。唯一的区别是我导入了一个org.holoeverywhere.widget.ListView而不是经典的ListView。

这是我的MainActivity：

import android.support.v4.app.FragmentManager;

import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.view.Menu;

import com.googlecode.androidannotations.annotations.AfterViews;
import com.googlecode.androidannotations.annotations.EActivity;
import com.googlecode.androidannotations.annotations.ViewById;

import org.holoeverywhere.app.Activity;
import org.holoeverywhere.widget.ArrayAdapter;
import org.holoeverywhere.widget.DrawerLayout;
import org.holoeverywhere.widget.ListView;

@EActivity(R.layout.activity_main)
public class MainActivity
    extends Activity {


// Declare Variables
ActionBar mActionBar;
@ViewById(R.id.drawer_layout)
DrawerLayout mDrawer;
@ViewById(R.id.left_drawer)
ListView mDrawerList;
private String[] mPlanetTitles;

@AfterViews
protected void useElements() {


    // Activate Navigation Mode Tabs
    mActionBar = getSupportActionBar();

    // Locate ViewPager in activity_main.xml
    mPlanetTitles = getResources().getStringArray(R.array.planets_array);

    // Activate Fragment Manager
    FragmentManager fm = getSupportFragmentManager();

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.drawer_list_item, mPlanetTitles);

    // Set the adapter for the list view
    mDrawerList.setAdapter(adapter);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getSupportMenuInflater().inflate(R.menu.activity_main, menu);
    return super.onCreateOptionsMenu(menu);
}

}

我的activity_main.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<org.holoeverywhere.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- The navigation drawer -->
    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp" />
</org.holoeverywhere.widget.DrawerLayout>

修改

drawer_list_item.xml：

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:gravity="center_vertical"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:textColor="#fff"
    android:background="?android:attr/activatedBackgroundIndicator"
    android:minHeight="?android:attr/listPreferredItemHeightSmall"/>

这段代码应该向我展示里面有行星列表的抽屉。 适用于Android 4.x设备，因为未使用HoloEverywhere类。但是在2.x上它会因以下异常而崩溃：

如果我对该行发表评论：

mDrawerList.setAdapter(adapter);

在我的MainActivity中，它在2.x上运行，我得到一个空白的抽屉。

Answer 1

问题出在drawer_list_item.xml中。在Android 2.x中，以“？android：attr /”开头的样式属性不可用。删除它们解决了问题。

使用HoloEverywhere Listview进行InflateException
