After I updated Android Studio to v3.1.3 I am having this rendering issue!
build.grandle (app)
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.android.support:design:28.0.0-alpha3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}
I had a similar problem, it was resolved by changing this line
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
to
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'
It helped me resolve my rendering problems
