Android Design Support Library(二)用NavigationView实现抽屉菜单界面
NavigationView在MD设计中非常重要,之前Google也提出了使用DrawerLayout来实现导航抽屉。这次,在Android Design Support Library中,Google提供了NavigationView来实现导航菜单界面。
这次我们写的代码在Android用TabLayout实现类似网易选项卡动态滑动效果这篇文章代码的基础上进行修改,所以最好先看看上面这篇文章
首先仍旧是配置build.gradle:
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:design:22.2.0'
    compile 'com.android.support:recyclerview-v7:22.2.0'
    compile 'com.android.support:cardview-v7:22.2.0'
}

‘com.android.support:design:22.2.0’com.android.support:design:22.2.0就是我们需要引入的Android Design Support Library,其次我们还引入了Recyclerview和Cardview。

DrawerLayout标签包含了主界面的布局以及抽屉的布局,NavigationView标签下app:headerLayout=”” 可以引入头部文件 
app:menu=”“则引入菜单的布局。
头部布局文件(navigation_header.xml)

        setSupportActionBar(toolbar);
        final ActionBar ab = getSupportActionBar();
        ab.setHomeAsUpIndicator(R.drawable.ic_menu);
        ab.setDisplayHomeAsUpEnabled(true);
        mViewPager = (ViewPager) findViewById(R.id.viewpager);

        NavigationView navigationView =

        if (navigationView != null) {
            navigationView.setNavigationItemSelectedListener(

        }
        initViewPager();

navigationView.setNavigationItemSelectedListener对菜单的条目进行了监听,如果被点击则将条目设置为选中状态并收回抽屉。当然别忘了对toolbar的菜单选项进行监听回调,否则抽屉就出不来了。 
(TabLayoutActivity.java)
  @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                mDrawerLayout.openDrawer(GravityCompat.START);
                return true;
        }
        return super.onOptionsItemSelected(item);
    }
