DrawerLayout must be measured with MeasureSpec.EXACTLY error

Question

I am trying to implement a Navigation drawer, but I keep getting this error. I saw the similar questions but did not work for me. I have the following layout activity_main2.

Answer 1

You could try to set Exactly measurements explicitly always like below:

public class MyDrawerLayout extends DrawerLayout {

    public MyDrawerLayout(@NonNull Context context) {
        super(context);
    }

    public MyDrawerLayout(@NonNull Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public MyDrawerLayout(@NonNull Context context, @Nullable AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        widthMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.EXACTLY);
        heightMeasureSpec = MeasureSpec.makeMeasureSpec(MeasureSpec.getSize(heightMeasureSpec), MeasureSpec.EXACTLY);

        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
    }
}
