操作栏不显示与 PagerSlidingTabStrip
Actionbar not showing with PagerSlidingTabStrip
我使用 PagerSlidingTabStrip 创建了一个滑动标签。它创建正确但操作栏丢失它显示如下:
是否可以帮助我解决为什么操作栏被禁用的问题。
import com.astuetz.PagerSlidingTabStrip;
public class SMainTabActivity extends FragmentActivity implements ETabFragment.OnFragmentInteractionListener,
MTabFragment.OnFragmentInteractionListener{
public String classSelected;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setProgressBarIndeterminateVisibility(true);
setProgressBarIndeterminateVisibility(false);
setContentView(R.layout.activity_subject_main_tab);
Bundle b = getIntent().getExtras();
classSelected = b.getString("classId");
// Get the ViewPager and set it's PagerAdapter so that it can display items
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
viewPager.setAdapter(new TabFragmentPagerAdapter(getSupportFragmentManager()));
// Give the PagerSlidingTabStrip the ViewPager
PagerSlidingTabStrip tabsStrip = (PagerSlidingTabStrip) findViewById(R.id.tabs);
// Attach the view pager to the tab strip
tabsStrip.setViewPager(viewPager);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.activity_main_actionsbar, menu);
return super.onCreateOptionsMenu(menu);
// getMenuInflater().inflate(R.menu.activity_main_actionsbar, menu);
//return true;
}

</application>
预计是:
可能只是因为在您的 xml 文件中,您将 Actionbar 设置为 0dp。另一个问题可能是您没有为应用程序使用正确的主题。获取操作栏的主题将在您的 style.xml 中设置,如下所示:
<style name="MyMaterialTheme" parent="MyMaterialTheme.Base">
</style>
<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowNoTitle">true</item>
<item name="windowActionBar">true</item>
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
然后在您的 AndroidManifest.xml 中调用它,如下所示:
android:theme="@style/MyMaterialTheme"
注意:您需要将 styles.xml 中的颜色添加到您的选择中。
此外,如果您完全卡住了,请使用此示例以获得更好的 Android 支持 Material 设计指南 http://www.android4devs.com/2014/12/how-to-make-material-design-app.html
我遇到了同样的问题,要解决它,只需扩展 ActionBarActivity 而不是 FragmentActivity 即可。
