How do you pass the gravity attribute via xml for a custom view?
android, android-custom-view, android-xml
Solution
by writing:
<attr format="integer" name="android:gravity"/>
you are intruducing the new attribute `android:gravity` with integer format, of course `android:gravity` is already defined in the system, so you need to change it into:
<attr name="android:gravity"/>
Problem
I'm trying to figure out how to pass `android:gravity` via xml for a custom view. The solution posted here (https://stackoverflow.com/a/3441986/413254) says to add the `android:gravity` attribute to the other attr's. When I do this, I end up with a warning saying: /Users/greg/dev/company/mobile/my_app/app/src/main/res/values/colors.xml Error:Attribute "android:gravity" has already been defined Error:Execution failed for task ':app:processStagingDebugResources'. com.android.ide.common.internal.LoggedErrorException: Failed to run command: /Users/greg/dev/android-sdk/sdk/build-tools/21.0.2/aapt package -f --no-crunch -I /Users/greg/dev/android-sdk/sdk/platforms/android-21/android.jar -M /Users/greg/dev/company/mobile/myapp/app/build/intermediates/manifests/full/staging/debug/AndroidManifest.xml -S /Users/greg/dev/company/mobile/myapp/app/build/intermediates/res/staging/debug -A /Users/greg/dev/company/mobile/myapp/app/build/intermediates/assets/staging/debug -m -J /Users/greg/dev/company/mobile/myapp/app/build/generated/source/r/staging/debug -F /Users/greg/dev/company/mobile/myapp/app/build/intermediates/res/resources-staging-debug.ap_ --debug-mode --custom-package com.company.vendorreviews -0 apk --output-text-symbols /Users/greg/dev/company/mobile/myapp/app/build/intermediates/symbols/staging/debug Error Code: 1 Output: /Users/greg/dev/company/mobile/myapp/app/build/intermediates/res/staging/debug/values/values.xml:165: error: Attribute "android:gravity" has already been defined My colors.xml file?

Theme, FlowLayout (library I include), LinearLayoutCompat, etc. Edit: Updated error message.
