问题描述

我目前正在构建具有动态的复选框使用内容从Web服务的一组行。然而，这ListView的将需要做的pretty的多少什么preferenceActivity将完成。我不知道的行数的内容是动态的，所以我不能创建每个复选框preference XML格式。我如何着手建立一个preferenceActivity，将显示一个未知数量的行用一个CheckBox prefence动态使用严格的Java？

I am currently building out a list of rows with checkboxes dynamically using content from a web service. However, this ListView will need to do pretty much what a PreferenceActivity would accomplish. I don't know the number of rows as the content is dynamic so I can't create each CheckBoxPreference in xml. How do I go about building a PreferenceActivity that will display an unknown number rows with a CheckBoxPrefence dynamically using strictly Java?

由于时间提前帮助。

推荐答案

我认为你在寻找这样的事情：

I think you're looking for something like this:

public class MyPreferenceActivity extends PreferenceActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.my_preference_activity);

        //fetch the item where you wish to insert the CheckBoxPreference, in this case a PreferenceCategory with key "targetCategory"
        PreferenceCategory targetCategory = (PreferenceCategory)findPreference("targetCategory");

        //create one check box for each setting you need
        CheckBoxPreference checkBoxPreference = new CheckBoxPreference(this);
        //make sure each key is unique  
        checkBoxPreference.setKey("keyName");
        checkBoxPreference.setChecked(true);

        targetCategory.addPreference(checkBoxPreference);
    }
}
