タブ共有を使用したAndroid SharedPreferences

Question

私は2つのタブ（フラグメント）と1つの主なアクティビティを持っています。フラグメント2では、値を格納し、前の値が大きいかどうかを確認するためにSharedPerferencesを使用します。そうであれば、それを高い値に置き換えます。フラグメント1は値の表示にのみ使用されます。アプリを開くと、フラグメント1がデフォルトのフラグメントになります。フラグメント2では

：フラグメント1では

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE); 
SharedPreferences.Editor editor = sharedPref.edit(); 

int score = sharedPref.getInt("marks", 0); 

if (newS > score) { //newS is the new score 
    editor.putInt("marks", newS); 
    editor.commit(); 
} 

：

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE); 
int score = sharedPref.getInt("marks", 0); 
x.setText(score); //x is a text view. 

しかし、私はそれを実行すると、アプリが閉じ続けます。 x.setText(score)が、スコアは、文字列ressourcesのIDと一致していません。

Answer 1

あなたはint型でテキストを設定してみてください。

あなたはあなたができることのTextViewにスコア値を表示したい場合：x.setText(String.valueOf(score));
