我試圖保存一個int,我從EditText中獲得,並且正如人們所說的那樣,最適合使用SharedPreference,我傾聽了,但是每次我嘗試保存/加載時,程序崩潰!有任何想法嗎?Android SharedPreference不能正常工作
public static final String MY_PREFS_NAME = "MyPrefsFile";
String getsturdvalue;
int sturd;
EditText sturdadapter;
int sturdadaptercount;
public void onSave(View view) {
SharedPreferences.Editor editor = (SharedPreferences.Editor) getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE);
editor.putInt(getstrengthvalue, strnth);
editor.apply();
}
public void onLoad(View view) {
SharedPreferences prefs = getSharedPreferences(MY_PREFS_NAME, MODE_PRIVATE);
String restoredText= prefs.getString("text", null);
if (restoredText != null) {
int insertvalue = prefs.getInt("insertvalue", strnth);
int adapter = prefs.getInt("adapter", strengthadaptercount);
}
strengthadapter.setText(prefs.getInt("" ,strengthadaptercount));
}
