Android从支持库添加抽屉布局

我正在尝试使用android支持库在姜饼项目中创建抽屉导航。我已成功安装了支持库，并尝试将字符串数组传递到抽屉列表中，但数组中出现空指针异常，不确定原因。有人知道如何在旧版本的Android中正确实现抽屉布局吗

这是我到目前为止所做的，我不确定这样做是否正确

mainpage.java

 String[] mPlanetTitles = {
                "Abundance",
                "Anxiety",
                "Bruxism",
                "Discipline",
                "Drug Addiction"
        };

        //mPlanetTitles = getResources().getStringArray(R.array.menu_array);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.left_drawer);

        // Set the adapter for the list view
        mDrawerList.setAdapter(new ArrayAdapter<String>(this,
                R.layout.drawer_list_item, android.R.id.text1, mPlanetTitles));


    }

在.java文件导航抽屉适配器上，您正在引用android.R.id.text1，但在.xml文件上，您有“@+id/textView1”，因此它会引发空指针异常

将.xml文件TextView id更改为android:id=“@android:id/text1”，它应该开始工作

<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="wrap_content"  >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="18dp"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>
