DrawerLayout的布局及实现

实现关键代码：

首先是我们的主布局，注意：最外层要是DrawerLayout哦！！！！

activity_main.xml：

.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">

    "@+id/ly_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    "@+id/list_left_drawer"
        android:layout_width="180dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#080808"
        android:choiceMode="singleChoice"
        android:divider="#FFFFFF"
        android:dividerHeight="1dp" />

.support.v4.widget.DrawerLayout>

接着ListView的布局代码和domain类：Item比较简单，就不给出了，直接上中间Fragment的 
布局以及代码吧！另外Adapter直接复用我们之前写的那个可复用的MyAdapter！

fg_content.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv_content"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:textSize="25sp" />

ContentFragment.java：

/**
 * Created by Jay on 2015/10/8 0008.
 */
public class ContentFragment extends Fragment {

    private TextView tv_content;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fg_content, container, false);
        tv_content = (TextView) view.findViewById(R.id.tv_content);
        String text = getArguments().getString("text");
        tv_content.setText(text);
        return view;
    }
}

最后是我们的Activity类

MainActivity.java：

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener{

    private DrawerLayout drawer_layout;
    private ListView list_left_drawer;
    private ArrayList menuLists;
    private MyAdapter myAdapter = null;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        drawer_layout = (DrawerLayout) findViewById(R.id.drawer_layout);
        list_left_drawer = (ListView) findViewById(R.id.list_left_drawer);

        menuLists = new ArrayList();
        menuLists.add(new Item(R.mipmap.iv_menu_realtime,"实时信息"));
        menuLists.add(new Item(R.mipmap.iv_menu_alert,"提醒通知"));
        menuLists.add(new Item(R.mipmap.iv_menu_trace,"活动路线"));
        menuLists.add(new Item(R.mipmap.iv_menu_settings,"相关设置"));
        myAdapter = new MyAdapter(menuLists,R.layout.item_list) {
            @Override
            public void bindView(ViewHolder holder, Item obj) {
                holder.setImageResource(R.id.img_icon,obj.getIconId());
                holder.setText(R.id.txt_content, obj.getIconName());
            }
        };
        list_left_drawer.setAdapter(myAdapter);
        list_left_drawer.setOnItemClickListener(this);
    }


    @Override
    public void onItemClick(AdapterView parent, View view, int position, long id) {
        ContentFragment contentFragment = new ContentFragment();
        Bundle args = new Bundle();
        args.putString("text", menuLists.get(position).getIconName());
        contentFragment.setArguments(args);
        FragmentManager fm = getSupportFragmentManager();
        fm.beginTransaction().replace(R.id.ly_content,contentFragment).commit();
        drawer_layout.closeDrawer(list_left_drawer);
    }
}
