在我的主要活动中有一个工具栏和tabLayout,它由3个带有viewPager的片段组成。问题是当我不隐藏我的工具栏时,每个片段的布局都不适合屏幕。但是当我隐藏工具栏时,每个工作都很好,所有碎片都适合整个屏幕。我不知道我的代码有什么问题
可以看到,我只能看到标签然后隐藏它应该是的工具栏。当我隐藏而不是隐藏工具栏时,如何解决这个问题以适应我的布局。
我的片段xml。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<com.github.mikephil.charting.charts.LineChart
android:id="@+id/linechart"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
这是我的主要活动。
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager vpPager = (ViewPager) findViewById(R.id.viewpager);
adapterViewPager = new PagerAdapter(getSupportFragmentManager());
application = (MainApplication) getApplicationContext();
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
this.setTitle("Hi: " + application.getEmail());
TabLayout tabs = (TabLayout) findViewById(R.id.tabs);
vpPager.setAdapter(adapterViewPager);
tabs.setupWithViewPager(vpPager);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}

答案 0 :(得分:0)
如果您在活动布局中使用android:fillViewport="true"
..请使用此..
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways|snap"
android:background="#6495ED"
android:gravity="end"
android:layout_gravity="end"
/>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#6495ED"
/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:fillViewport="true"
>
<android.support.v4.view.ViewPager
android:id="@+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.widget.NestedScrollView>
到你的nestedScrollView ..
