如何使ActionBar和堆叠的Bar共享相同的背景图像 [英] How to make ActionBar and stacked bar share same background image

问题描述

动作栏和它的堆叠栏(其中一个包含导航选项卡)是否可以共享相同的背景图片?一个从动作栏开始到结束于堆叠栏的地方?

is it possible for actionbar and it's stacked bar(one that contain navigation tabs) to share same background image? one that starts from actionbar and ends at stacked bar?

当前的实现方式是，最终使操作栏具有自己的图像，而堆叠栏具有其自己的图像.

currently the way am implementing this, am ending up having action bar with it own image and stacked bar with its own.

我的styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="android:actionBarStyle">@style/MyActionBar</item>
    <item name="android:actionMenuTextColor">@color/app_yellow</item>
    <item name="android:windowActionBarOverlay">true</item>

    <!-- Support library compatibility -->
    <item name="actionBarStyle">@style/MyActionBar</item>
    <item name="actionMenuTextColor">@color/app_yellow</item>
</style>

<!-- ActionBar styles -->
<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">

    <item name="android:titleTextStyle">@style/MyActionBarTitleText</item>

    <item name="android:actionBarTabTextStyle">@style/MyActionBarTabText</item>

    <item name ="android:actionBarTabStyle">@style/MyTabStyle</item>

    <item name="background">@drawable/actionbar</item>

</style>

 <!-- individual ActionBar tabs style -->
<style name="MyTabStyle" parent ="Widget.AppCompat.Light.ActionBar.TabView">
    <item name ="background">@android:color/transparent</item>
    <item name ="android:background">@android:color/transparent</item>

</style>

我的活动

  @Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

   ActionBar actionBar = getSupportActionBar();
    // Specify that tabs should be displayed in the action bar.
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
    actionBar.setLogo(R.mipmap.ic_launcher);
    actionBar.setDisplayUseLogoEnabled(true);
    actionBar.setDisplayShowHomeEnabled(true);
    actionBar.setStackedBackgroundDrawable(getResources().getDrawable(R.drawable.actionbar));

推荐答案

从 Michael De Soto 指导(请参见上面的评论)，我能够使Actionbar和Stacked Bar通过相同的背景图像共享使用具有

From Michael De Soto guidance(see his comment above), i was able to have actionbar and stacked bar share same background image by using a toolbar that has

• 视图中的操作栏详细信息(例如图标，标题)(标题为textview，图标为imageview等)

• actionbar details(e.g icons,titles) in views(textview for titles, imageviews for icons etc)

在选项卡布局中堆叠的栏详细信息(基本上是选项卡).

Stacked bar details(basically tabs) in a tablayout.

这是我实施的方式

我的活动xml

<android.support.v7.widget.Toolbar
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:id="@+id/mainActivityBar"
    android:layout_alignParentTop="true"
    android:background="@drawable/actionbar"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    app:contentInsetEnd="0dp"
    app:contentInsetRight="0dp"
  >
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:text="President"
            android:id="@+id/appname_1"
            android:background="@android:color/transparent"
            android:textColor="#ffffff"
            android:layout_marginLeft="20dp" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabs"
            style="@style/myCustomTabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@android:color/transparent"
            android:layout_below="@+id/appname_1"
            android:layout_alignParentEnd="true"
            android:layout_alignParentStart="false"
            android:layout_alignParentLeft="false"
            android:layout_alignParentRight="true"
            android:layout_alignParentBottom="false"
            android:layout_alignLeft="@+id/appname_1"
            app:tabGravity="fill"
            app:tabMode="scrollable"/>
    </RelativeLayout>

</android.support.v7.widget.Toolbar>

在我的styles.xml中添加了以下内容

<style name="mainActivityTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <!--We will be using the toolbar so no need to show ActionBar-->
    <item name="android:windowActionBar">false</item>

</style>

<style name="myCustomTabLayout" parent="Widget.Design.TabLayout">
    <item name="tabIndicatorColor">?attr/colorAccent</item>
    <item name="tabIndicatorHeight">2dp</item>
    <item name="tabSelectedTextColor">?android:textColorPrimary</item>
</style>

最后，我的活动

public class MainActivity extends AppCompatActivity {

private SectionsPagerAdapter mSectionsPagerAdapter;

TabLayout tabLayout;

private ViewPager mViewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    Toolbar toolbar =(Toolbar) findViewById(R.id.mainActivityBar);
     setSupportActionBar(toolbar);

    tabLayout = (TabLayout) findViewById(R.id.tabs);

    // Create the adapter that will return a fragment for each of the three
    // primary sections of the activity.
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

    // Set up the ViewPager with the sections adapter.
     mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(mSectionsPagerAdapter);
    mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

    tabLayout.setupWithViewPager(mViewPager);
}

public class SectionsPagerAdapter extends FragmentStatePagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        // getItem is called to instantiate the fragment for the given page.
        switch (position) {
            case 0:
              return Item1fragment.newInstance();
            case 1:

                return Item2fragment.newInstance();
            case 2:
                return Item3fragment.newInstance();

        }
        return null;
    }

    @Override
    public int getCount() {
        // Show 3 total pages.
        return 3;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        Locale l = Locale.getDefault();
        switch (position) {
            case 0:
                return "Item1;
            case 1:
              return "Item2";
            case 2:
               return "Item3";
        }
        return "";
    }
 }

}
