設定画面でタイトルバーを非表示にしようとしていますが、通常はrequestWindowFeature(Window.FEATURE_NO_TITLE);
うまくいかない、何か提案はありますか?
私のコードは次のとおりです。
私のマニフェストの場合:
<activity
android:name=".prefs"
android:label="@string/app_name"
android:theme="@android:style/Theme.NoTitleBar">
<intent-filter>
<action android:name="com.mittereder.rockpaper.PREFS" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
ジャワ:
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.prefs);
requestWindowFeature(Window.FEATURE_NO_TITLE);
