android SwitchPreference ListPreference使用

<headerandroid:fragment="kadacom.com.pad.ui.activity.progressbar.SettingsActivity$GeneralPreferenceFragment"android:icon="@drawable/ic_info_black_24dp"android:title="@string/pref_header_general" />

有这种的不多说，直接 SwitchPreference

package  xxxx.com.pad.ui.activity.progressbar;import android.media.Ringtone;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Bundle;
import android.preference.ListPreference;
import android.preference.Preference;
import android.preference.PreferenceFragment;
import android.preference.PreferenceManager;
import android.preference.RingtonePreference;
import android.preference.SwitchPreference;
import android.provider.Settings;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.text.TextUtils;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;import com.sdsmdg.tastytoast.TastyToast;import xxxxx.com.pad.R;import static android.os.ParcelFileDescriptor.MODE_WORLD_READABLE;public class PrefereFragment extends PreferenceFragment {private SwitchPreference mMistakeTouchPreference;private static final String MISTAKE_TOUCH_MODE_KEY = "nice";@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);addPreferencesFromResource(R.xml.pref_general);//        bindPreferenceSummaryToValue(findPreference("example_switch"));bindPreferenceSummaryToValue(findPreference("example_text"));bindPreferenceSummaryToValue(findPreference("example_list"));
//        bindPreferenceSummaryToValue(findPreference("nice"));initMistakeTouchPreference();}private void initMistakeTouchPreference() {mMistakeTouchPreference = (SwitchPreference)findPreference(MISTAKE_TOUCH_MODE_KEY);mMistakeTouchPreference.setOnPreferenceChangeListener(new Preference.OnPreferenceChangeListener() {@Overridepublic boolean onPreferenceChange(Preference preference, Object objValue) {final String key = preference.getKey();System.out.print("key--"+key);if (MISTAKE_TOUCH_MODE_KEY.equals(key)){if (mMistakeTouchPreference.isChecked() != (Boolean)objValue) {boolean value = (Boolean)(objValue);mMistakeTouchPreference.setChecked(value);//最自己的设置}}return true;}});}@Overridepublic void onViewCreated(View view, @Nullable Bundle savedInstanceState) {super.onViewCreated(view, savedInstanceState);}private static void bindPreferenceSummaryToValue(Preference preference) {preference.setOnPreferenceChangeListener(sBindPreferenceSummaryToValueListener);sBindPreferenceSummaryToValueListener.onPreferenceChange(preference,PreferenceManager.getDefaultSharedPreferences(preference.getContext()).getString(preference.getKey(), ""));}private static Preference.OnPreferenceChangeListener sBindPreferenceSummaryToValueListener = new Preference.OnPreferenceChangeListener() {@Overridepublic boolean onPreferenceChange(Preference preference, Object value) {String stringValue = value.toString();if (preference instanceof ListPreference) {// For list preferences, look up the correct display value in// the preference's 'entries' list.ListPreference listPreference = (ListPreference) preference;int index = listPreference.findIndexOfValue(stringValue);// Set the summary to reflect the new value.preference.setSummary(index >= 0? listPreference.getEntries()[index]: null);//                TastyToast.makeText(get,stringValue+"", TastyToast.LENGTH_SHORT, 2);} else if (preference instanceof RingtonePreference) {// For ringtone preferences, look up the correct display value// using RingtoneManager.if (TextUtils.isEmpty(stringValue)) {// Empty values correspond to 'silent' (no ringtone).preference.setSummary(R.string.pref_ringtone_silent);} else {Ringtone ringtone = RingtoneManager.getRingtone(preference.getContext(), Uri.parse(stringValue));if (ringtone == null) {// Clear the summary if there was a lookup error.preference.setSummary(null);} else {// Set the summary to reflect the new ringtone display// name.String name = ringtone.getTitle(preference.getContext());preference.setSummary(name);}}} else {// For all other preferences, set the summary to the value's// simple string representation.preference.setSummary(stringValue);}return true;}};
}

bindPreferenceSummaryToValue 这个方法支持自动生成的代码里面说的
只是适用这几个
// Bind the summaries of EditText/List/Dialog/Ringtone preferences
// to their values. When their values change, their summaries are
// updated to reflect the new value, per the Android Design
// guidelines.

SwitchPreference 要用的话，单独写Listener 下

pref_general.xml

<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"><SwitchPreferenceandroid:defaultValue="true"android:key="nice"android:summary="@string/pref_description_social_recommendations"android:title="@string/pref_title_social_recommendations" /><!-- NOTE: EditTextPreference accepts EditText attributes. --><!-- NOTE: EditTextPreference's summary should be set to its value by the activity code. --><EditTextPreferenceandroid:capitalize="words"android:defaultValue="@string/pref_default_display_name"android:inputType="textCapWords"android:key="example_text"android:maxLines="1"android:selectAllOnFocus="true"android:singleLine="true"android:title="@string/pref_title_display_name" /><!-- NOTE: Hide buttons to simplify the UI. Users can touch outside the dialog todismiss it. --><!-- NOTE: ListPreference's summary should be set to its value by the activity code. --><ListPreferenceandroid:defaultValue="-1"android:entries="@array/pref_example_list_titles"android:entryValues="@array/pref_example_list_values"android:key="example_list"android:negativeButtonText="@null"android:positiveButtonText="@null"android:title="@string/pref_title_add_friends_to_messages" /></PreferenceScreen>

然后添加下这个 PrefereFragment

public class ActivityPreferenceFragmentActivity extends AppCompatActivity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_preference_fragment);FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction();fragmentTransaction.replace(R.id.frame_container, new PrefereFragment()).commit();}
}

activity_preference_fragment.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"tools:context="kadacom.com.pad.ui.activity.progressbar.ActivityPreferenceFragmentActivity"><FrameLayoutandroid:id="@+id/frame_container"android:layout_width="match_parent"android:layout_height="match_parent" /></android.support.constraint.ConstraintLayout>

activity 等地方获取具体参数

  SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);String nide = prefs.getString("example_list","");System.out.println(nide)；
