问题描述
有关早期的大号preVIEW有一些例子如下所示添加到您的code,以使用FAB(浮动操作按钮)。
但遗憾的是我不能用同样的code实现的FAB,由于没有被支持了,但它似乎已经取代了另一种方法setOutline法fab.setOutlineProvider(ViewOutlineProvider); 。任何人都可以解释如何使用呢?...
这可能是很简单的东西,我很想念,但任何帮助将是非常美联社preciated。
//大纲
INT大小= getResources()getDimensionPixelSize(R.dimen.fab_size)。
概述概述=新纲要();
outline.setOval(0,0,大小,尺寸);
按钮FAB =(按钮)findViewById(R.id.fab);
fab.setOutline(提纲);
fab.setClipToOutline(真正的);
只是为了完成@ianhanniballake答案:
按钮FAB =(按钮)findViewById(R.id.fab);
//外形轮廓=新纲要();
//outline.setOval(0,0,大小,尺寸);
//fab.setOutline(outline);
ViewOutlineProvider viewOutlineProvider =新ViewOutlineProvider(){
@覆盖
公共无效getOutline(查看视图,外形轮廓){
//或者直接从视图的宽/高读取大小
INT大小= getResources()getDimensionPixelSize(R.dimen.fab_size)。
outline.setOval(0,0,大小,尺寸);
}
};
fab.setOutlineProvider(viewOutlineProvider);
For the earlier L Preview there were some examples like shown below to add to your code in order to use an FAB (Floating Action Button).
But unfortunately I can't use that same code to implement an FAB due to the setOutline method not being supported anymore, but it appears to have been replaced by an alternative method 'fab.setOutlineProvider(ViewOutlineProvider);'. could anyone explain how to use this?...
It is probably something really simple that I am missing, but any help would be much appreciated.
// Outline
int size = getResources().getDimensionPixelSize(R.dimen.fab_size);
Outline outline = new Outline();
outline.setOval(0, 0, size, size);
Button fab = (Button) findViewById(R.id.fab);
fab.setOutline(outline);
fab.setClipToOutline(true);
Just to complete the @ianhanniballake answer:
Button fab = (Button) findViewById(R.id.fab);
//Outline outline = new Outline();
//outline.setOval(0, 0, size, size);
//fab.setOutline(outline);
ViewOutlineProvider viewOutlineProvider = new ViewOutlineProvider() {
@Override
public void getOutline(View view, Outline outline) {
// Or read size directly from the view's width/height
int size = getResources().getDimensionPixelSize(R.dimen.fab_size);
outline.setOval(0, 0, size, size);
}
};
fab.setOutlineProvider(viewOutlineProvider);
