问题 I am trying to make my RelativeLayout background image animate-able by trying to set number of image frames. Here is how I set the animation private View fullView; fullView = (View)findViewById(R.id.fullView); Resources res = getResources(); Drawable drawable = res.getDrawable(R.drawable.eng_anim_1); drawable.setAlpha(100); fullView.setBackgroundDrawable(drawable); AnimationDrawable progressAnimation = (AnimationDrawable) fullView.getBackground(); progressAnimation.start(); Here is my 'list

问题 I'm attempting to modify a drag and drop gridView example to use a specific drawable instead of the bitmap used in the example. I believe I'll need to edit the line: Bitmap bmp = Bitmap.createBitmap(150, 150, Bitmap.Config.RGB_565); and change it to something such as Bitmap bmp = R.drawable.sqwhite; but I don't think that's exactly what I'm looking for. Any suggestions? Source: public class DraggableGridViewSampleActivity extends Activity { static Random random = new Random(); static String[]

问题 I have an image that is the background of one activity in my app. For the Samsung Galaxy S4 this image should be 1920x1080 and placed at the xxhdpi folder. For the Nexus 10 this image should be 2560x1600 and placed at the xhdpi folder. It's nonsense to place an image bigger in the xhpdi folder than an image placed at the xxhdpi folder. And because that I believe that I misunderstood something. Can someone explain what I misunderstood? --edit-- For all the answer questioning if the nexus10 is

问题 I have tried multiple solutions to this but none seem to work! I am currently using the following Drawable as a divider (this is the horizontal example but the same approach works for vertical too, switching height for width). LinearLayout linearLayout; // set with findViewById linearLayout.setDividerDrawable(getResources().getDrawable(R.drawable.divider)); linearLayout.setShowDividers(SHOW_DIVIDER_MIDDLE); Where divider looks like this: <?xml version="1.0" encoding="utf-8"?> <shape xmlns

问题 I have a Button that has a BitmapDrawable and a row of text in it. Not that it matter but my drawable is "above" my text which would correspond to the third button from the top. The drawable is set using: BitmapDrawable top = new BitmapDrawable(mContext.getResources(), Bitmap.createScaledBitmap(buttonContent.content, mContext.IMAGE_WIDTH, mContext.IMAGE_HEIGHT, false)); button.setCompoundDrawablesWithIntrinsicBounds(null, top.getCurrent(), null, null); The image that I set initially changes

问题 I want to draw a custom shape in xml layout like below : I tried to do some code in XML but i do not understand how to give shadow effect to outline of this shadow.

问题 I made this: ShapeDrawable.ShaderFactory shaderFactory = new ShapeDrawable.ShaderFactory() { @Override public Shader resize(int width, int height) { LinearGradient linearGradient = new LinearGradient(0, 0, width, height, new int[]{ 0xF44336, 0xFFB74D, 0xFFE082, 0xAED581, 0x4CAF50, 0xAED581, 0xFFE082, 0xFFB74D, 0xF44336}, new float[]{ 0, 0.125f, 0.25f, 0.375f, 0.5f, 0.625f, 0.75f, 0.875f, 1.0f}, Shader.TileMode.REPEAT); return linearGradient; } }; PaintDrawable paint = new PaintDrawable();
