我的活动扩展了FragmentActivity并实现了ActionBar.TabListener。在FragmentActivity中实现导航抽屉
所以现在我要实现的抽屉式导航，让我改变我的布局在此：
<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" >
<!-- The main content view -->
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
<!-- The navigation drawer -->
<ListView
android:id="@+id/drawer"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#F3F3F4"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp" ></ListView>
</android.support.v4.widget.DrawerLayout>
和我的代码Java中的提取物是：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager) findViewById(R.id.pager);
mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
ab = getActionBar();
ab.setHomeButtonEnabled(false);
ab.setDisplayHomeAsUpEnabled(true);
ab.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
for (String tab_name : tabs) {
ab.addTab(ab.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
ab.setSelectedNavigationItem(position);
}
@Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
@Override
public void onPageScrollStateChanged(int arg0) {
}
});
Bundle extras = getIntent().getExtras();
rowID = extras.getString(Home.ROW_ID);
Data = extras.getStringArrayList(Home.ROW_ID1);
status = extras.getInt(Home.ROW_ID2);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawer.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
_initMenu();
mDrawerToggle = new CustomActionBarDrawerToggle(this, mDrawer);
mDrawer.setDrawerListener(mDrawerToggle);
}
但我有错误我的logcat：

，这是错误的logcat中的代码，在NsMenuAdapter类：
public View getView(int position, View convertView, ViewGroup parent) {
NsMenuItemModel item = getItem(position);
ViewHolder holder = null;
View view = convertView;
if (view == null) {
int layout = R.layout.ns_menu_row_counter;
if (item.isHeader)
layout = R.layout.ns_menu_row_header;
view = LayoutInflater.from(getContext()).inflate(layout, null);
TextView text1 = (TextView) view.findViewById(R.id.menurow_title);
ImageView image1 = (ImageView) view.findViewById(R.id.menurow_icon);
TextView textcounter1 = (TextView) view.findViewById(R.id.menurow_counter);
view.setTag(new ViewHolder(text1, image1,textcounter1));
}
if (holder == null && view != null) {
Object tag = view.getTag();
if (tag instanceof ViewHolder) {
holder = (ViewHolder) tag;
}
}
if(item != null && holder != null)
{
if (holder.textHolder != null)
holder.textHolder.setText(item.title);
if (holder.textCounterHolder != null){
if (item.counter > 0){
holder.textCounterHolder.setVisibility(View.VISIBLE);
holder.textCounterHolder.setText(""+item.counter);
}else{
holder.textCounterHolder.setVisibility(View.GONE);
}
}
if (holder.imageHolder != null) {
if (item.iconRes > 0) {
holder.imageHolder.setVisibility(View.VISIBLE);
holder.imageHolder.setImageResource(item.iconRes);
} else {
holder.imageHolder.setVisibility(View.GONE);
}
}
}
return view;
}
