android - onPreferenceClick 监听器不工作/onPreferenceClick 未被调用

Question

我试图在点击我的一个偏好设置时打开一个网站(而不是在偏好设置实际更改时因为没有一个)。

问题是永远不会调用 onPreferenceClick()。

这是我的PreferenceActivity:

public class About extends PreferenceActivity implements
        OnPreferenceClickListener {

TextView tv_developer;
TextView tv_version;
String versionName;

int counter = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        addPreferencesFromResource(R.xml.about);        

        Preference p_developer = (Preference) findPreference("p_developer");
        p_developer.setOnPreferenceClickListener(this);

        Preference p_licences = (Preference) findPreference("p_licences");
        p_licences.setOnPreferenceClickListener(this);



    }

    @Override
    public boolean onPreferenceClick(Preference pref) {
        // TODO Auto-generated method stub

        Log.i("Anything pressed", "YES");
        if (pref.getKey().equals("p_developer")) {
            Log.i("p_developer", "YES");


        } else {
            Log.i("p_developer", "NO");
        }
        return true;
    }   
}

这是 xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
    android:key="about"
    android:title="About" >


    <Preference
        style="?android:preferenceInformationStyle"
        android:key="p_licences"
        android:title="p_licences" />

    <PreferenceCategory android:title="Category" >

        <Preference
            style="?android:preferenceInformationStyle"
            android:key="p_developer"
            android:title="p_developer" />

    </PreferenceCategory>

</PreferenceScreen>

我还发现这也没有做任何事情:

<Preference android:title="@string/prefs_web_page" >
    <intent android:action="android.intent.action.VIEW"
            android:data="http://www.example.com" />
</Preference>

Answer 1

将android:enabled="true" 添加到Preference:

<Preference
    style="?android:preferenceInformationStyle"
    android:key="p2"
    android:enabled="true"
    android:title="p2" />
