drawable

问题 Scaling with ScaleDrawable is not working for me. The drawable is remained in the same size. LayerDrawable layerDrawable = new LayerDrawable(layers); Drawable d = layerDrawable.getCurrent(); ScaleDrawable sd = new ScaleDrawable(d, 0, 0.01f, 0.01f); return sd.getDrawable(); What i need to do to fix it? Thanks. 回答1: You need to set the level: LayerDrawable layerDrawable = new LayerDrawable(layers); Drawable d = layerDrawable.getCurrent(); ScaleDrawable sd = new ScaleDrawable(d, 0, 0.01f, 0.01f)

问题 I am new to Android and Java but have managed to teach myself and find most answers to questions on stackoverflow without needing to ask questions. Until now.... Here goes, I have many colored buttons which, when clicked, change color to a range of different colors. There are many buttons defined for example as: <Button android:id="@+id/button17" android:layout_width="0dp" android:layout_height="fill_parent" android:layout_weight="1" android:background="@drawable/orange_button" android

问题 I'm using the windowTranslucentStatus in my app theme. Now, also want to tint the status bar to match my ActionBar. Currently I'm using the SystemBarTint library, which is mostly fine except of one problem: When the application launches, the OS shows a themed mockup layout as a splash image during the actual inflation. At that stage, there is no status bar tinting yet. It looks like that (Took me 5 times to capture this screenshot during app launch): Only after the activity is fully loaded

问题 Is there a way to tell if the Drawable I'm getting back from getApplicationIcon() is a default/built-in icon or not? For example, I have several applications installed on my emulator. "Adobe Reader" has an icon provided by Adobe. "com.android.gesture.builder" and "Sample Soft Keyboard", on the other hand, have a generic Android icon. getApplicationIcon() for those two packages returned different BitmapDrawable objects, but running getBitmap() on those two objects returned the same Bitmap

问题 I need an xml drawable (for a cordova splash screen) in android. I Want to display a transparent logo centered on the screen (without stretching), while the rest of the screen has a background color set. What I tried first, was to add only the image in the xml file: <?xml version="1.0" encoding="utf-8"?> <bitmap android:src="@drawable/splashscreen" android:gravity="center_horizontal|center_vertical" /> This showed the logo centered on the screen, but (obviously) has no background color. So I

问题 I have an android application which can playback audio/video and show pictures. For videos I want to overlay a play button on top of the preview image and also in list views.. Right now how I'm doing it is with an ImageView in xml, and then the drawable is a layer layer-list which I define programmatically because one of the images is dynamic, the play button is static of course. I want to align the play button 10px from the bottom, and centered horizontally. My ImageView is defined like this

问题 I am busy creating a less complicated version of NinePatchDrawable that tiles the inner panels instead of stretching them. I can implement the actual logic to do the rendering and such. However, I can't find documentation about how to use this Drawable in the XML files. Is this possible? That is, can I have a <tileable-nine-patch> , or some such, tag I can use to define resources? 回答1: Unfortunately it is not possible to use custom drawables in XML files (for API 23 and below) due to
