Android: Custom Drawable in a SeekBar widget is drawing aliased images

由 本秂侑毒 提交于 2019-12-06 13:39:22
问题 Problem is when I am using a custom progressDrawable in a SeekBar widget (perhaps incorrectly) it is rendered in a very aliased/ugly/low quality form. I have set "drawingCacheQuality" to high and there is no difference. Anyone have any ideas? Am developing on a Nexus One (OS 2.2.1) with target build for project as API 1.5 (though I would hope that shouldn't matter). Here is a sample of what it looks like: My aim is to create a simple nifty visual switch with two states (on and off), and a

In my main activity I'm doing this: @Override public boolean onCreateOptionsMenu(Menu menu) { getSupportMenuInflater().inflate(R.menu.activity_main, menu); return true; } And here is my activity_main.xml: <menu xmlns:android="http://schemas.android.com/apk/res/android" > <item android:id="@+id/transparency_seekbar" android:showAsAction="never" android:title="test" android:actionViewClass="android.widget.SeekBar"/> </menu> So far as I know this isn't possible to customize the options-menu,

how to change SeekBar color in android? (Programmatically)

问题 I made an equalizer to go with my app but I am not sure how I can change the seekbar's thumb and progress color. It seems to be pink by default and that doesn't fit my app's aesthetics.

SeekBar Holo Theme using Support Library

由 白昼怎懂夜的黑 提交于 2019-12-06 02:42:19
I am using the Android Support Library v4 and v7 to get Fragments, Swipe-able View Pagers, and even ActionBar! It works and the graphics are really nice! However while the graphics for the above look nice and consistent in Android 2.x and Android 4.x, some common widgets look very different between versions. This leads to colours mismatch inside the app with an otherwise consistent look UI - so no matter what I draw in the rest of the UI, either the yellow SeekBar or blue SeekBar won't match something. I thought the whole point of the support library is to get a consistent UI across platforms,
