I want to create custom compound view. This view works fine in runtime, but fails to draw itself in layout preview. To investigate this problem, i created simple compound view, here's example:
import android.content.Context;
import android.support.v4.content.ContextCompat;
import android.util.AttributeSet;
import android.view.Gravity;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
import my.testproject.coreui.R;
public class ImageWithCaption3 extends LinearLayout {
private TextView textView;
public ImageWithCaption3(Context context) {
this(context, null);
}
public ImageWithCaption3(Context context, AttributeSet attrs) {
this(context, attrs, 0);
init();
}
public ImageWithCaption3(
Context context,
AttributeSet attrs,
int defStyleAttr) {
super(context, attrs, defStyleAttr);
init();
}
private void init() {
setOrientation(VERTICAL);
textView = new TextView(getContext());
LayoutParams layoutParams = new LayoutParams(
128,
ViewGroup.LayoutParams.WRAP_CONTENT
);
layoutParams.gravity = Gravity.CENTER_HORIZONTAL;
textView.setLayoutParams(layoutParams);
textView.setTextColor(ContextCompat.getColor(getContext(), R.color.core_ui_gray));
textView.setText("Test text");
addView(textView);
}
}
Stacktrace:

Project is multimodule, and view declared in library module. This library module used by every other module in app.
Constant 0x7F060034 appears in every module's R file as non-final constant, and as final 0x7f060044 in application's R file.
Also i tried to inflate some layout file inside init() method, and this layout resource also failed to resolve. I tried to clear, rebuild, invalidate caches, and reimport project. This issue repeats on other computers as well.
Android studio 3.2, gradle-4.9
I think there's a bug in resource linker in android studio layout preview, or i somehow misconfigured my project. I created this custom view in application module, and it displays fine in layout preview.
