列表視圖中的Android複選框

Question

我有一個從數據庫填充的列表視圖，以及每行的複選框。使用putExtras將值傳遞給另一個Activity的TextView。現在，當您重新啓動應用程序時，我想在TextView中顯示用複選框選擇的最後一個值。我需要SharedPreferences還是有方法？由於

保存在您的偏好複選框如下：

//method to load the sharedpreferences. 
private void loadSavedPreferences() { 
    SharedPreferences sharedPreferences = PreferenceManager 
      .getDefaultSharedPreferences(this); 
    boolean checkBoxValue = sharedPreferences.getBoolean("CheckBox_Value", false); 
    String name = sharedPreferences.getString("storedName", "YourName"); 
    if (checkBoxValue) { 
     checkBox.setChecked(true); 
    } else { 
     checkBox.setChecked(false); 
    } 

    textview.setText(name); 
} 
    //store boolean value of checkbox in sharedpreferences. 
private void savePreferences(String key, boolean value) { 
    SharedPreferences sharedPreferences = PreferenceManager 
      .getDefaultSharedPreferences(this); 
    Editor editor = sharedPreferences.edit(); 
    editor.putBoolean(key, value); 
    editor.commit(); 
} 
    //store the string sharedpreference. 
private void savePreferences(String key, String value) { 
    SharedPreferences sharedPreferences = PreferenceManager 
      .getDefaultSharedPreferences(this); 
    Editor editor = sharedPreferences.edit(); 
    editor.putString(key, value); 
    editor.commit(); 
} 

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    savePreferences("CheckBox_Value", checkBox.isChecked()); 
    savePreferences("storedName", textview.getText().toString()); 

}
