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);
}
}
