在我的活动中,我根据存储的偏好更新用户界面。对于updateUI代码如下:不共享偏好不被保存

private void updateUI() 
{ 
    //preferences = getSharedPreferences(Select.PREF_FILE_NAME, MODE_PRIVATE); 
    preferences = PreferenceManager.getDefaultSharedPreferences(getApplicationContext()); 

    toggle = (Button)findViewById(R.id.toggleButton); 
    incommingEdit = (Button)findViewById(R.id.IncommingEditButton); 
    outgoingEdit = (Button)findViewById(R.id.outgoingEditButton); 
    missedEdit = (Button)findViewById(R.id.missedEditButton); 
    save = (Button)findViewById(R.id.saveButton); 
    cancel = (Button)findViewById(R.id.cancelButton); 
    incommingCheck = (CheckBox)findViewById(R.id.incommingCheck); 
    outgoingCheck = (CheckBox)findViewById(R.id.outgoingCheck); 
    missedCheck = (CheckBox)findViewById(R.id.missedCheck); 
    incommingTextView = (TextView) findViewById(R.id.incommingTextView); 
    outgoingTextView = (TextView) findViewById(R.id.outgoingTextView); 
    missedTextView = (TextView) findViewById(R.id.missedTextView); 

    //Disable all the edit buttons until their checkboxes are checked. 
    incommingEdit.setEnabled(false); 
    outgoingEdit.setEnabled(false); 
    missedEdit.setEnabled(false); 

    //Display the messages in the text views. 
    incommingTextView.setText(preferences.getString("incommingMsgPhone", "Currently there are no messages saved.")); 
    outgoingTextView.setText(preferences.getString("outgoingMsgPhone", "Currently there are no messages saved.")); 
    missedTextView.setText(preferences.getString("missedMsgPhone", "Currently there are no messages saved.")); 

    //Check the check boxes. 
    if(preferences.getInt("incommingPhone", 0) == Calls.INCOMING_TYPE) 
    { 
     incommingCheck.setChecked(true); 
     incommingEdit.setEnabled(true); 
    } 

    if(preferences.getInt("outgoingPhone", 0) == Calls.OUTGOING_TYPE) 
    { 
     outgoingCheck.setChecked(true); 
     outgoingEdit.setEnabled(true); 
    } 

    if(preferences.getInt("missedPhone", 0) == Calls.MISSED_TYPE) 
    { 
     missedCheck.setChecked(true); 
     missedEdit.setEnabled(true); 
    } 

    //Check if the application is on or off and set the text of the button. 
    //preferences = getSharedPreferences(Select.PREF_FILE_NAME, MODE_PRIVATE); 
    boolean on = preferences.getBoolean("isOn", false); 
    if(!on) 
     toggle.setText("Turn On"); 
    else 
     toggle.setText("Turn off"); 
} 

这里是我如何保存所有这些首选项:

save.setOnClickListener(new OnClickListener() 
    { 

     @Override 
     public void onClick(View v) 
     { 
      // TODO Auto-generated method stub 
      //Save all in the preference file and exit. 
      //preferences = getSharedPreferences(Select.PREF_FILE_NAME, MODE_PRIVATE); 
      Editor editor = preferences.edit(); 
      editor.putInt("incommingPhone", incomming); 
      editor.putInt("outgoingPhone", outgoing); 
      editor.putInt("missedPhone", missed); 

      editor.putString("incommingMsgPhone", incommingMsg); 
      editor.putString("outgoingMsgPhone", outgoingMsg); 
      editor.putString("missedMsgPhone", missedMsg); 

      editor.commit(); 
      finish(); 
     } 
    }); 

我的UI更新正确的第二次,我跑我的应用程序,但围绕第三次或第四次我得到默认首选项值。我甚至尝试使用getdefaultpreferences而不是getsharedpreferences,但没有运气。

试试这个..

preferences = activity.getSharedPreferences("Share", Context.MODE_PRIVATE);`

谢谢,但我也试过这种方法,但不知何故,我的喜好被删除。 – coders1290

它的例子:

public void saveFavName(String what) 
     { 


      myPrefs= getSharedPreferences("myPrefs", MODE_PRIVATE); 
      SharedPreferences.Editor es = myPrefs.edit(); 
      es.putString("value", what); // add or overwrite someValue 
       es.commit(); // this saves to disk and notifies observers 
     }

我有一个类似的问题

- 我的字符串变量被保留,但没有别的。 作为一个穷人的解决方法,我将所有东西都保存为字符串。

尝试在使用前清除编辑器。换句话说:

Editor editor = preferences.edit(); 
editor.clear(); 
editor.putInt("incommingPhone", incomming); 
editor.commit(); 

我有和你一样的问题,这对我有效。对于我的整个代码示例见this post on my blog

我有getStringSet类似的问题,documatation帮助有

请注意,您不能修改此调用返回集合实例。 如果存储数据的一致性不能保证,也不能保证您完全可以修改该实例。
