我正在制作一个应用程序，我跑到一个路障。 基本上我有一个复选框...如果复选框被选中，它应该允许在编辑文本首选项中输入文本，并使用该值。但问题出在这里......如果该框未被选中，它将使用EditTextPreference中的值。如果该框被选中，则使用硬编码值。我的活动应用程序做对面的复选框应该做什么
部分：
private void loadURI()
{
PreferenceManager.setDefaultValues(this, R.xml.settings, true);
SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
if (settings.getBoolean("default_uri", false)){
String defaultURI = getString(R.string.dream_uri);
this.mWebView.loadUrl(defaultURI);
}
else {
String customURI = settings.getString("custom_uri", "");
this.mWebView.loadUrl(customURI);
}
}
将Settings.xml：
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory
android:title="Backdrop Settings" >
<CheckBoxPreference
android:title="Use Custom Backdrop URL"
android:id="@id/checkBox1"
android:key="default_uri"
android:defaultValue="true"/>
<EditTextPreference
android:title="Custom Backdrop URL"
android:summary="Tap here to enter custom URL"
android:id="@id/editText1"
android:defaultValue="Enter Custom URL here"
android:key="custom_uri"
android:dependency="default_uri" />
<CheckBoxPreference
android:title="Use a Custom Slideshow Period?"
android:key="slide_duration"
android:defaultValue="false"/>
<ListPreference
android:title="Slideshow Duration"
android:summary="How long should each slide be displayed?"
android:key="list_duration"
android:dependency="slide_duration"/>
</PreferenceCategory>
<PreferenceCategory
android:title="Other">
<Preference
android:title="Test Dream"
android:summary="Tap here to test the dream"
android:key="testDream" />
<Preference
android:title="About"
android:key="AboutApp"
android:summary="About this app" />
</PreferenceCategory>
</PreferenceScreen>
我的首选活动：提前
public class mollySettings extends PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
addPreferencesFromResource(R.xml.settings);
Preference button = findPreference("testDream");
button.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference arg0) {
final Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.android.systemui", "com.android.systemui.Somnambulator");
startActivity(intent);
return true;
}
});
Preference about = findPreference("AboutApp");
about.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
@Override
public boolean onPreferenceClick(Preference arg1) {
final Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setClassName("com.death2all110.flogging.molly", "com.death2all110.flogging.molly.About");
startActivity(intent);
return true;
}
});
}
}
感谢，并请让我知道如果有是你需要的东西
