我正在尝试为我的Android应用程序构建设置活动，它适用于肖像，但是当我打开横向模式时它会崩溃

这是我的代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_height="wrap_content"
  android:layout_width="wrap_content">

<fragment     android:name="project.android.udacity.com.popularmovies.app.SettingsFragment"
    android:id="@+id/settings_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</fragment>
</LinearLayout>


public class SettingsFragment extends PreferenceFragment {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addPreferencesFromResource(R.xml.pref_general);
} }

public class SettingsActivity extends AppCompatActivity {

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

    getFragmentManager().beginTransaction()
            .replace(R.id.settings_content, new SettingsFragment())
            .commit();
} }

和错误日志

我不知道如何解决它，为什么肖像作品？

2 个答案:

答案 0 :(得分：1)

您不需要以下代码

getFragmentManager().beginTransaction()
        .replace(R.id.settings_content, new SettingsFragment())
        .commit();

因为您的片段已在XML中定义。

答案 1 :(得分：0)

覆盖onCreateView类，而不是onCreate类中的SettingsFragment方法。

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View fragmentView = inflater.inflate(R.layout.your_fragment_layout, container, true);

    return fragmentView;
}
