Android Design Support控件之DrawerLayout简单使用

DrawerLayout能够让我们在项目中非常方便地实现側滑菜单效果。如今主流的应用如QQ等都

採用的这样的效果。

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。可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的基础上加入的布局和代码。

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>

側滑菜单左側的布局

<?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));//加入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);

    }

}
