Is there a way I can get application from Context. I noticed that activity and service has getApplication() method but Context does not.
Background:
I am using/extending the GCMBaseIntentService and the
protected abstract void onMessage (Context context, Intent intent)
gives me a context as a parameter. I would like to get the Application object so I can downcast it to MyApplication and retrieve some variables
Thanks
Context#getApplicationContext
将返回您的Application
实例。
val application : Application = context.applicationContext as Application
For those looking for an answer in kotlin:
@BindingAdapter("app:setSelectArea")
@JvmStatic
fun setSelectArea(view: ImageView, mContext: ContextX){
view.setOnClickListener {
val application = view.context.applicationContext as Application
val viewModel:KnowledgeViewModel by lazy { KnowledgeViewModel(application) }
val mKnowledge = Knowledge(
"",
"abcdefg test",
""
)
viewModel.firebaseInsertKnowledge(mKnowledge)
}
}
