Android PreferenceFragmentCompat标题空白
Android PreferenceFragmentCompat标题空白
提问于 2018-11-17 11:47:33
我不知道为什么使用这个片段会造成问题，似乎isIconSpaceReserved = false对不适用于preferenceCagory很有用
class TFragment : PreferenceFragmentCompat() {
override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
val context = preferenceManager.context
val screen = preferenceManager.createPreferenceScreen(context)
val category1 = PreferenceCategory(context)
category1.title = "button"
category1.summary = "what is the problem"
category1.key = "bbb"
val swithButton = SwitchPreferenceCompat(context)
swithButton.title = "button"
swithButton.summary = "summary"
swithButton.key = "sss"
swithButton.isIconSpaceReserved = false
val swithButton2 = EditTextPreference(context)
swithButton2.title = "edit"
val swithButton3 = SeekBarPreference(context)
swithButton3.title = "seekbar"
swithButton3.value = 1
screen.addPreference(category1)
category1.addPreference(swithButton)
val category2 = PreferenceCategory(context)
category2.title = "category2"
screen.addPreference(category2)
category2.addPreference(swithButton2)
category2.addPreference(swithButton3)
preferenceScreen = screen
}风格是正常的，我尝试了很多方法，但它是无用的。

现在，我尝试了'androidx.preference:preference:1.1.0-alpha01‘，非常幸运，它修复了isIconSpaceReserved不支持PreferenceCategory的错误。
override fun setPreferenceScreen(preferenceScreen: PreferenceScreen?) {
super.setPreferenceScreen(preferenceScreen)
if (preferenceScreen != null) {
val count = preferenceScreen.preferenceCount
for (i in 0 until count) {
if (preferenceScreen.getPreference(i) is PreferenceCategory) {
val category = preferenceScreen.getPreference(i) as PreferenceCategory
val childCount = category.preferenceCount
for (j in 0 until childCount) {
category.getPreference(j).isIconSpaceReserved = false
}
}
preferenceScreen.getPreference(i).isIconSpaceReserved = false
}
}
