android - 使用支持库删除操作栏下方的阴影和线条

Question

由于 ActionBar.TabListener 现已弃用，我已按照本教程设置 Material Design 滑动标签:

http://www.android4devs.com/2015/01/how-to-make-material-design-sliding-tabs.html

它有效，但我试图删除操作栏下方的线条+阴影但没有成功。即使设置 getSupportActionBar().setElevation(0);正如其他线程中所建议的那样。

我知道如果我将 Activity 的自定义样式设置为 @style/Theme.AppCompat 而不是 @style/Theme.AppCompat.Light (实际配置) 线条+阴影消失了，但是选项菜单和共享此样式的其他 Activity 变暗了。我不想要它。

所以我试图找到一种方法来删除线条+阴影并保持主要样式为“光”。

主 Activity (创建时)

public class MainActivity extends AppCompatActivity {

// Declaring Your View and Variables

Toolbar toolbar;
ViewPager pager;
ViewPagerAdapter adapter;
SlidingTabLayout tabs;
CharSequence Titles[]={"1","2","3","4"};
int Numboftabs =4;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getSupportActionBar().setElevation(0);
    setContentView(R.layout.activity_main);

    //
    // Creating The Toolbar and setting it as the Toolbar for the activity

    toolbar = (Toolbar) findViewById(R.id.tool_bar);
    //setSupportActionBar(toolbar);

    // Creating The ViewPagerAdapter and Passing Fragment Manager, Titles fot the Tabs and Number Of Tabs.
    adapter =  new ViewPagerAdapter(getSupportFragmentManager(),Titles,Numboftabs);

    // Assigning ViewPager View and setting the adapter
    pager = (ViewPager) findViewById(R.id.pager);
    pager.setAdapter(adapter);

    // Assiging the Sliding Tab Layout View
    tabs = (SlidingTabLayout) findViewById(R.id.tabs);
    tabs.setDistributeEvenly(true); // To make the Tabs Fixed set this true, This makes the tabs Space Evenly in Available width

    // Setting Custom Color for the Scroll bar indicator of the Tab View
    tabs.setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
        @Override
        public int getIndicatorColor(int position) {
            return getResources().getColor(R.color.darkgreen);
        }
    });

    // Setting the ViewPager For the SlidingTabsLayout
    tabs.setViewPager(pager);



}

Answer 1

在AppBarLayout中添加app:elevation="0dp"，用于在App Bar中隐藏阴影。
