You can fetch it from the current theme in this way: private int fetchAccentColor() { TypedValue typedValue = new TypedValue(); TypedArray a = mContext.obtainStyledAttributes(typedValue.data, new int[] { R.attr.colorAccent }); int color = a.getColor(0, 0); a.recycle(); return color; }
I could rotate in XML: <?xml version=”1.0″ encoding=”utf-8″?> <rotate xmlns:android=”http://schemas.android.com/apk/res/android” android:fromDegrees=”90″ android:toDegrees=”90″ android:pivotX=”50%” android:pivotY=”50%” android:drawable=”@drawable/mainmenu_background”> </rotate> The fromDegrees is important. Basically this is a rotate animation defined in XML. With fromDegrees you define the initial rotated state. The toDegrees is the final rotated state of the drawable in the animation sequence but can be anything … Read more
INVISIBLE: This view is invisible, but it still takes up space for layout purposes. GONE: This view is invisible, and it doesn’t take any space for layout purposes.
You use a typed array in arrays.xml file within your /res/values folder that looks like this: <?xml version=”1.0″ encoding=”utf-8″?> <resources> <integer-array name=”random_imgs”> <item>@drawable/car_01</item> <item>@drawable/balloon_random_02</item> <item>@drawable/dog_03</item> </integer-array> </resources> Then in your activity, access them like so: TypedArray imgs = getResources().obtainTypedArray(R.array.random_imgs); // get resource ID by index, use 0 as default to set null resource imgs.getResourceId(i, 0) … Read more
Replace buildConfigField “long”, “FACEBOOK_APP_ID”, FACEBOOK_APP_ID with resValue “string”, “FACEBOOK_APP_ID”, FACEBOOK_APP_ID then rebuild your project (Android Studio -> Build -> Rebuild Project). The two commands both produce generated values – consisting of Java constants in the first case, and Android resources in the second – during project builds, but the second method will generate a string … Read more
Use following layerlist: <?xml version=”1.0″ encoding=”utf-8″?> <layer-list xmlns:android=”http://schemas.android.com/apk/res/android” > <item> <shape android:shape=”rectangle” android:padding=”10dp”> <corners android:bottomRightRadius=”5dp” android:bottomLeftRadius=”5dp” android:topLeftRadius=”5dp” android:topRightRadius=”5dp”/> </shape> </item> <item android:drawable=”@drawable/image_name_here” /> </layer-list>
See in the android sdk directory. In \platforms\android-X\data\res\values\themes.xml: <item name=”textAppearanceLarge”>@android:style/TextAppearance.Large</item> <item name=”textAppearanceMedium”>@android:style/TextAppearance.Medium</item> <item name=”textAppearanceSmall”>@android:style/TextAppearance.Small</item> In \platforms\android-X\data\res\values\styles.xml: <style name=”TextAppearance.Large”> <item name=”android:textSize”>22sp</item> </style> <style name=”TextAppearance.Medium”> <item name=”android:textSize”>18sp</item> </style> <style name=”TextAppearance.Small”> <item name=”android:textSize”>14sp</item> <item name=”android:textColor”>?textColorSecondary</item> </style> TextAppearance.Large means style is inheriting from TextAppearance style, you have to trace it also if you want to see full definition of … Read more
Instead of a shape, you could try a View: <View android:layout_width=”1dp” android:layout_height=”match_parent” android:background=”#FF0000FF” /> I have only used this for horizontal lines, but I would think it would work for vertical lines as well. Use: <View android:layout_width=”match_parent” android:layout_height=”1dp” android:background=”#FF0000FF” /> for a horizontal line.
I figured it out! The answer is to NOT specify the namespace in the style. <?xml version=”1.0″ encoding=”utf-8″ ?> <resources xmlns:android=”http://schemas.android.com/apk/res/android”> <style name=”CustomStyle”> <item name=”android:layout_width”>wrap_content</item> <item name=”android:layout_height”>wrap_content</item> <item name=”custom_attr”>value</item> <!– tee hee –> </style> </resources>
I believe that was already answered here. String versionName = getPackageManager().getPackageInfo(getPackageName(), 0).versionName; OR int versionCode = getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
