Android devのサンプルコードに従って、アクティビティのフラグメントを膨らませようとしています。私が取り組んでいるより複雑なプロジェクトがありますが、ここでこの単純なものと同じエラーが発生しています。誰かが私を正しい方向に向けることができますか?
フラグメントを拡張するクラス
package com.example.fragtest;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class FragOne extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState){
return inflater.inflate(R.layout.activity_main, container,false);
}
}
FragmentActivity を拡張するクラス
package com.example.fragtest;
import android.os.Bundle;
import android.view.Menu;
import android.support.v4.app.FragmentActivity;
public class MainActivity extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
フラグメントがあるxml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment android:name="com.example.fragtest.FragOne"
android:id="@+id/frag"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
アクティビティ名が設定されたマニフェスト
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.fragtest"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="15" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
これがlogcat出力です
