DataBindingUtil.setContentView - Type parameter T has incompatible upper bounds

Question

\"Android Studio\" shows error message \"Type parameter T has incompatible upper bounds: ViewDataBinding and ActivityChecklistsBinding.

ActivityChecklistsBindin         


        

Answer 1

When I first meet this error, I create a layout named a.xml, and then I Create a Activity like this

public class ABinding extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ABinding binding = DataBindingUtil.setContentView(this, R.layout.a);
    }

}

and this error occurs. Finally I found out Class ABinding was automatically generated in /build, so activity with name ABinding will overwrite the auto generated class

so I rename the Activity and the error disappear
