SharedPreferences的问题

Question

我想通过sharepreferance将字符串存储在内存中但是有一些问题无法存储在内存中你能告诉我如何才能解决这个问题？ 需要任何许可吗？

码：：

SavePreferences("MEM1", LanguageSelcted); 
LoadPreferences();

方法：：

public void SavePreferences(String key, String value) {
            try {
                SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
                SharedPreferences.Editor editor = sharedPreferences.edit();
                editor.putString(key, value.trim());
                editor.commit();
            } catch (Exception e) {

            e.printStackTrace();

            }

private void LoadPreferences() {
        try {
            SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
            LanguageSelection = sharedPreferences.getString("MEM1", "");
            Log.i(TAG, "LanguageSelection is :>>>" + LanguageSelection);
            Toast.makeText(getBaseContext(), "LanguageSelection is :>>>" + LanguageSelection, Toast.LENGTH_LONG).show();
            /*
             * textSavedMem1.setText(strSavedMem1);
             * textSavedMem2.setText(strSavedMem2);
             */
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Answer 1

保存应该是

SharedPreferences myPrefs1 = this.getSharedPreferences(
                                "update", MODE_PRIVATE);
                        SharedPreferences.Editor prefsEditor = myPrefs1.edit();
                        prefsEditor.putString("URL", apkurl);
                        prefsEditor.commit();

应该得到

SharedPreferences pref = this.getSharedPreferences("update",
                MODE_PRIVATE);
        String key = pref.getString("URL", "");

getSharedPreferences将采用两个参数。

Answer 2

有一点突出的是这条线：

LanguageSelection = sharedPreferences.getString("MEM1", "");

应该有参考......

LanguageSelection whateverNameYouWant = sharedPreferences.getString("MEM1", "");

或者你的意思是......

String LanguageSelection = sharedPreferences.getString("MEM1", "");
