如何使用SeekBarPreference显示查找栏值

<PreferenceCategory 
     android:title="Delay between change image">

     <SeekBarPreference
         android:id="@+id/preference_delay_seek_bar"
         android:title="Value"
         android:defaultValue="1"
         android:max="60"/>

</PreferenceCategory>

Answer 1

就像这样：

((SeekBarPreference) findPreference(R.id.preference_delay_seek_bar)).setOnPreferenceChangeListener(new OnPreferenceChangeListener() {
  @Override
  public boolean onPreferenceChange(Preference preference, Object newValue) {
    final int progress = Integer.valueOf(String.valueOf(newValue));
    preference.setSummary(String.format("My progress value: %d", progress));
  }
});

Answer 2

使用JetPack，我可以简单地向SeekBarPreference XML元素添加以下属性。

app:showSeekBarValue="true"
