我需要在我的 Android 应用程序中添加抽屉导航菜单。我的应用程序有很多模块，因此我无法对每个 Activity 进行编码以显示导航菜单。所以我决定将导航菜单代码放入我的基本 Activity 中。所以每个 Activity 都扩展了这个基本 Activity 。抽屉导航菜单工作正常，但问题是 Activity 组件无法工作。我不知道发生了什么事。是否需要做出任何改变？提前致谢。
baseActivity.java
public class BaseActivity extends ActionBarActivity {
RelativeLayout fullLayout;
DrawerLayout dLayout;
@Override
public void setContentView(int layoutResID) {
fullLayout = (RelativeLayout) getLayoutInflater().inflate(
R.layout.activity_base, null);
FrameLayout frameLayout = (FrameLayout) fullLayout
.findViewById(R.id.content_frame);
ListView dList = (ListView) fullLayout.findViewById(R.id.left_drawer);
dLayout = (DrawerLayout) fullLayout.findViewById(R.id.drawer_layout);
getLayoutInflater().inflate(layoutResID, frameLayout, true);
setContentView(fullLayout);
String[] menu = new String[] { "Home", "Android", "Windows", "Linux",
"Raspberry Pi", "WordPress", "Videos", "Contact Us" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, menu);
dList.setAdapter(adapter);
dList.setSelector(android.R.color.holo_blue_dark);
dList.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View v, int position,
long id) {
dLayout.closeDrawers();
}
});
}};

此主页 Activity 和通用抽屉导航菜单显示正常，但主页 Activity 内的组件无法工作。但抽屉组件正在工作。
最佳答案
将主xml更改为这种方式并将侧菜单加载到侧菜单框架中:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.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" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="sas.mobi.lakshmi.main.BaseActivity" >
<FrameLayout
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<FrameLayout
android:id="@+id/side_menu"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>
