问题 In our android app, we use Jackson Annotations in our models: @JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "templateType", visible = true, defaultImpl = Default.class) @JsonSubTypes({ @Type(value = Subclass1.class, name = "tType1") We parse the json response using object mapper where klass is the class of the object file which we wish to parse to: getObjectMapper().readValue(json, klass); On rare scenarios on Android Lollipop devices, we get java

问题 I recently noticed that the Camera API is deprecated and I found the new API called Camera2. I have read the documentation but I don't really understand it. So my question is: how do I preview the front camera with the new camera api? Just a preview, not recording. I want to use this new API because in the future I'm guessing the current Camera API will be replaced and stop working. So I want to be prepared and just sit and watch while everyone panics. XD 回答1: First of all, find out the id of

问题 I am using an activity with a black background. That same activity has a toolbar and a DrawerLayout as well. This white screen makes the look inconsistent. It can become more apparent when there is a very slow Slide transition when opening an activity. Is there any way to remove this? Code that sets the enter transition on the second activity: if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { Window window = activity.getWindow(); Slide slide = new Slide(); slide.setSlideEdge

问题 New Android MediaStyle notifications in Lollipop don't have a dismiss button. Looks like there is already a bug for it on Google Code. Does anyone know what's a good workaround for this issue until the bug is resolved? Should we just delay switching to MediaStyle? Or use one of the actions as the dismiss button? 回答1: One mechanism which appears to work quite well is make the notification ongoing while music is playing and make it not ongoing (allowing it to be swipe dismissed) when the music

问题 I am attempting to show both a title, using setTitle and a custom view in my toolbar. I am not treating it as an actionbar, instead as nothing more than a view. I am adding both the titles and custom view in Java toolbar = (Toolbar) view.findViewById(R.id.toolbar); if (title != null) { toolbar.setTitle(title); toolbar.setTitleTextColor(getResources().getColor(android.R.color.white)); } if (subtitle != null) { toolbar.setSubtitle(subtitle); toolbar.setSubtitleTextColor(getResources().getColor

问题 I am writing an AccessibilityService for Android and, up to API level 20, I have been using the AccessibilityEvent.getSource() method to obtain a traversable AccessibilityNodeInfo when onAccessibilityEvent(AccessibilityEvent event) is triggered. Although the resulting AccessibilityNodeInfo does not always reflect the content of the screen, it is still possible to work with it. Starting on API level 21, the new AccessibilityService.getWindows() is supposed to be not only able to better

问题 This is addendum to my question SQLiteDatabase Cursor empty only on Android 5.0+ devices. That one will be closed as I was not sure what is causing the bug - thought it was a cursor note being properly filled. Now I have discovered what is causing empty cursor. Up to Android 5.0, search suggestions work by querying the database with the query: SELECT rowid AS _id, suggest_text_1, suggest_text_2, rowid AS suggest_intent_data_id FROM fts WHERE (fts MATCH ?) //for example '*e*' As of Android 5.0

问题 Hi I am developing android application in which I am trying to implement new material design features. I tried to apply both elevation property and TranslationZ property but it is not working. <Button android:id="@+id/button1" style="@style/ButtonStyle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:clickable="true" android:text="Name" /> <?xml version="1.0" encoding="UTF-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape=

问题 I want to use Material Theme in my application which has minimum sdk version of 8. As per docs - "The material theme is only available in Android 5.0 (API level 21) and above. The v7 Support Libraries provide themes with material design styles for some widgets and support for customizing the color palette." Does it mean I can use it if I add v7 Support Libarary in my project? Because after adding this library I got the following error: android:Theme.Material.Light requires API level 21
