在FragmentActivity中实现导航抽屉

标签： android android-fragments

我的Activity扩展了FragmentActivity并实现了ActionBar.TabListener。

所以现在我想实现导航抽屉，所以我改变了我的布局：

    <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>

我的代码Java的摘录是：

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);


}

但我的LogCat中有错误：

这是LogCat中的错误代码，在NsMenuAdapter类中：

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;                
    }

答案 0 :(得分：1)

它说资源未找到，从那我猜想TextView中的任何一个都无法从膨胀的布局中找到资源。 如果布局中有这些ID，请检查布局。
