getChildFragmentManager

getChildFragmentManager

错误:仅当android.support.v4.app.Fragment中有getChildFragmentManager()方法可用时,才可以使用'childFragmentManager'参数,请更新您的支持库版本。

我在我的gradle中编译了``com.android.support:support-v4:24.2.0''。我的代码像;

 import android.support.v4.app.Fragment;
 import org.androidannotations.annotations.*;
 import org.androidannotations.annotations.sharedpreferences.Pref;
.
.

@EFragment(R.layout.fragment_main)
public class MainFragment extends Fragment {
@Pref
ApplicationSettings_ applicationSettings;
@ViewById(R.id.bot)
public LinearLayout bot;
@ViewById(R.id.center)
public LinearLayout center;
@Bean
UIItemGenerator uiItemGenerator;
@SystemService
LayoutInflater layoutInflater;
@FragmentById(value = R.id.contentFragment,childFragment = true)
public ContentFragment contentFragment;

public MainFragment() {
}

@Click(R.id.imagebutton_ribbon)
public void ribbonClick(View view) {
    view.setVisibility(View.GONE);
}

.
.
.
@AfterViews
public void afterViews() {
    if (contentFragment == null)
        contentFragment = (ContentFragment) this.getChildFragmentManager().findFragmentById(R.id.contentFragment);
    for (int j = 0; j < bot.getChildCount(); j++) {
        bot.getChildAt(j).setSelected(false);
    }
    for (int j = 0; j < top.getChildCount(); j++) {
        top.getChildAt(j).setSelected(false);
    }
    ll_home.setSelected(true);
    ll_allrooms.setSelected(true);
    initUI();
    contentFragment.generateContent(-1, -1);
    imagebutton_top_rightarrow.setSelected(true);
    imagebutton_bot_rightarrow.setSelected(true);

最佳答案

getChildFragmentManager()是Fragment上的方法,并检查您的import语句

import android.support.v4.app.FragmentManager;


我认为您正在使用AppCompatActivity(FragmentActivity的子类),您必须使用此

getSupportFragmentManager()
