Android Design Support控件之DrawerLayout简单使用

DrawerLayout可以让我们在项目中很方便地实现侧滑菜单效果。现在主流的应用如QQ等都
采用的这种效果。这两天也是在学习Android Design Support的相关知识，网上有关这方面的文章介绍非常多，但是为了方便以后使用，还是把学习的知识做个简单记录。这次的代码也是在上一篇博客Android Design Support控件介绍之TabLayout的基础上添加的布局和代码。
主界面布局：

<?xml version="1.0" encoding="utf-8"?><android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:id="@+id/drawer_view"    android:layout_width="match_parent"    android:layout_height="match_parent">    <android.support.design.widget.NavigationView        android:id="@+id/navigation_view"        android:layout_width="200dp"        android:layout_height="match_parent"        android:layout_gravity="left"        android:fitsSystemWindows="true"        app:headerLayout="@layout/content_main"><!--content_main与上篇文章中一样-->    </android.support.design.widget.NavigationView></android.support.v4.widget.DrawerLayout>

侧滑菜单左侧的布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:padding="10dp">    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="40dp"        android:text="菜单ONE" />    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="20dp"        android:text="菜单TWO" />    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="20dp"        android:text="菜单THREE" />    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="20dp"        android:text="菜单FOUR" />    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="20dp"        android:text="菜单FIVE" /></LinearLayout>

Fragment界面布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    android:padding="10dp">    <TextView        android:id="@+id/content_tv"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_marginTop="40dp"        android:text="菜单ONE" /></LinearLayout>

主界面代码，TestAdapter 及TestFragment代码也同上一篇文章一样。

public class MainActivity extends FragmentActivity {    //便捷实现标签显示    private TabLayout tab_layout;    private ViewPager viewpager;    private TestAdapter mAdapter;    private List<Fragment> fragments;    private List<String> titles;    private DrawerLayout drawer_view;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.drawer_layout);        initViews();        initViewPages();    }    private void initViewPages() {        fragments = new ArrayList<>();        titles = new ArrayList<>();        for (int i = 0; i < 4; i++) {            String title="TAB" + i;            titles.add(title);            tab_layout.addTab(tab_layout.newTab().setText(title));//添加Tab标题            Fragment fragment = new TestFragment();            Bundle bundle = new Bundle();            bundle.putString("content", "这是第" + i + "个Fragment页面");            fragment.setArguments(bundle);            fragments.add(fragment);        }        mAdapter = new TestAdapter(this.getSupportFragmentManager(), titles, fragments);        viewpager.setAdapter(mAdapter);        tab_layout.setupWithViewPager(viewpager);        tab_layout.setTabsFromPagerAdapter(mAdapter);    }    private void initViews() {        tab_layout = (TabLayout) findViewById(R.id.tab_layout);        viewpager = (ViewPager) findViewById(R.id.viewpager);        drawer_view=(DrawerLayout)findViewById(R.id.drawer_view);        drawer_view.closeDrawer(GravityCompat.START);    }}
