我是 Android 新手，我有以下选项卡，我需要在选项卡之间建立分隔线 在此处输入图像描述

我想得到这样的东西

在此处输入图像描述

我已经在阅读这个，但解决方案来自 TabLayout，我正在使用 FragmentTabHost，但它没有用

这是我尝试实施的解决方案

在我的活动中

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search_flight);

        tabHost= (FragmentTabHost) findViewById(R.id.search_flight_tab_host);
        tabHost.setup(this, getSupportFragmentManager(),android.R.id.tabcontent);

        tabHost.addTab(tabHost.newTabSpec(Constants.SEARCH_FLIGHT_ROUND_TRIP).setIndicator(getString(R.string.round_trip)),
                SearchFlightRoundTripFragment.class, null);
        tabHost.addTab(tabHost.newTabSpec(Constants.SEARCH_FLIGHT_ONE_WAY).setIndicator(getString(R.string.one_way)),
                SearchFlightOneWayFragment.class, null);
        tabHost.addTab(tabHost.newTabSpec(Constants.SEARCH_FLIGHT_MULTIPLE).setIndicator(getString(R.string.multiple)),
                SearchFlightMultipleFragment.class, null);

        for (int i = 0; i < tabHost.getTabWidget().getChildCount(); i++) {
            View tabView = tabHost.getChildAt(i);
            if (tabView instanceof LinearLayout) {
                ((LinearLayout) tabView).setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);
                Drawable drawable = getDrawable(R.drawable.tab_divider);
                ((LinearLayout) tabView).setDividerDrawable(drawable);
            }
        }
    }

我的可绘制 tab_divider

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <size android:width="1dp" />
            <solid android:color="@color/colorBlack" />
        </shape>
    </item>

    <item
        android:bottom="16dp"
        android:top="12dp">

        <shape android:shape="rectangle">
            <solid android:color="@color/colorBlack" />
            <size android:width="1dp" />
        </shape>
    </item>
</layer-list>

感谢@MikeM 的评论，我能够解决问题，解决方案是下一个：

在活动中

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search_flight);

        tabHost= (FragmentTabHost) findViewById(R.id.search_flight_tab_host);
        tabHost.setup(this, getSupportFragmentManager(),android.R.id.tabcontent);

        tabHost.addTab(tabHost.newTabSpec(Constants.SEARCH_FLIGHT_ROUND_TRIP).setIndicator(getString(R.string.round_trip)),
                SearchFlightRoundTripFragment.class, null);
        tabHost.addTab(tabHost.newTabSpec(Constants.SEARCH_FLIGHT_ONE_WAY).setIndicator(getString(R.string.one_way)),
                SearchFlightOneWayFragment.class, null);
        tabHost.addTab(tabHost.newTabSpec(Constants.SEARCH_FLIGHT_MULTIPLE).setIndicator(getString(R.string.multiple)),
                SearchFlightMultipleFragment.class, null);
    }

                    android:orientation="vertical">

                    <TabWidget
                        android:id="@android:id/tabs"
                        style="@style/lightGrayLayout"
                        android:layout_width="match_parent"

                        android:showDividers="middle"/>

                    <FrameLayout
                        android:id="@android:id/tabcontent"
                        android:layout_width="match_parent"
                        android:layout_height="0dp"
                        android:layout_weight="1" />
                </LinearLayout>
            </android.support.v4.app.FragmentTabHost>

        </LinearLayout>
    </ScrollView>
</android.support.constraint.ConstraintLayout>

应该注意的是，属性android:divider="@color/colorBlack"它不是必须实现你想要的，无论有没有它，分界线都会出现，但是有了这个，可以将它们变暗一点，我希望这对其他人有帮助。
