i want create object factory using es6 old-style syntax doesn't work new. i have next code: export class column {} export class sequence {} export class checkbox {} export class columnfactory { constructor() { this.speccolumn = { __default: 'column', __sequence: 'sequence', __checkbox: 'checkbox' }; } create(name) { let classname = this.speccolumn[name] ? this.speccolumn[name] : this.speccolumn['__default']; return new window[classname](name); // line throw error } } let factory = new columnfactory(); let column = factory.create('username'); what do wrong? don't put class names on object. put classes there, don't have rely on them being global , accessible (in browsers) through window . btw, there's no reason make factory class, instantiate once (singleton). make object: export class column {} export class sequence {} expo...

so, have imageview inside framelayout. need way. feel issue here image , it's size itself. layout image pushes further down other views on screen leaving considerable empty space that's supposed layout. i found hard coding height value let's me minimize issue. if height wrap_content image reach same point blank space supposed layout extends extreme lengths. so want know if image size (or resolution?) problem (which seems be) or else, , if there better solution hardcoding layout height. in advance. here code: <linearlayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <framelayout android:layout_width="match_parent" android:layout_height="700dp"> <imageview android:id="@+id/image_header" android:layout_width="match_parent" android:layout_height=...
