I am trying to use DataBinding in my Android project where I code in Kotlin. First of all, I'm use DataBindingUtil.setContentView(layoutResId) method, it can run. Then I try to encapsulate DataBinding to BaseActivity, gradle build failed, I don't know why. Here is my code.
BaseActivity.kt
class BaseActivity<B : ViewDataBinding>
: AppCompatActivity(){
protected lateinit var mContext: AppCompatActivity
protected lateinit var mBinding: B
override fun onCreate(savedInstanceState: Bundle?) {
// Dagger2 注入
AndroidInjection.inject(this)
super.onCreate(savedInstanceState)
// 保存当前 Context 对象
mContext = this
// 添加到 AppManager 应用管理
AppManager.INSTANCE.addActivity(this)
}
override fun onDestroy() {
// 从应用管理移除当前 Activity 对象
AppManager.INSTANCE.removeActivity(this)
super.onDestroy()
}
override fun setContentView(layoutResID: Int) {
// 加载布局，初始化 DataBinding
mBinding = DataBindingUtil.inflate(
LayoutInflater.from(mContext),
layoutResID, null, false
)
super.setContentView(mBinding.root)
}
}
MainActivity.kt
class MainActivity : BaseActivity<ActivityMainBinding>() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
}

I don't know how to solve this problem, all my code is in KotlinTest, thanks for your help!
