【问题描述】:
我无法在任何其他堆栈帖子或 Android 文档中找到此问题的解决方案。出于某种原因,在使用 support.v4 库的 FragmentActivity 中,片段出现在 tabhost 后面,如下图所示:
MainActivity.java:
public class MainActivity extends FragmentActivity {
// Declare Variables
private FragmentTabHost mTabHost;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set the view from main_fragment.xml
setContentView(R.layout.main_fragment);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); //locks screen orientation to portrait
// Locate android.R.id.tabhost in main_fragment.xml
mTabHost = (FragmentTabHost) findViewById(android.R.id.tabhost);
// Create the tabs in main_fragment.xml
mTabHost.setup(this, getSupportFragmentManager(), R.id.tabcontent);
// Create Tab1 with a custom image in res folder
mTabHost.addTab(mTabHost.newTabSpec("tab1").setIndicator("Tab 1"),
FragmentTab1.class, null);
// Create Tab2
mTabHost.addTab(mTabHost.newTabSpec("tab2").setIndicator("Tab 2"),
FragmentTab2.class, null);
// Create Tab2
mTabHost.addTab(mTabHost.newTabSpec("tab3").setIndicator("Tab 3"),
FragmentTab3.class, null);
}
main_fragment.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.app.FragmentTabHost
android:id="@android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="@+id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
任何想法如何解决此问题并使片段的内容显示在选项卡下方?
谢谢
