今天学习了侧滑菜单的使用。

关键代码如下：

public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener{

    private DrawerLayout drawer_layout;
    private ListView list_left_drawer;
    private ArrayList<Item> menuLists;
    private MyAdapter<Item> 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<Item>();
        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<Item>(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);
    }
}
