如何在android中获取浮动按钮的徽章计数？

Question

我已经在下面提到了链接以获取浮动按钮。但我想在浮动按钮上显示徽章计数。（浮动按钮的调整方式是我们可以在屏幕上移动它）。我如何设置徽章计数呢？ 这里没有onclick我想显示带文字的浮动图标（徽章）。我怎么能这样做？

Answer 1

你需要为FloatingBubbleService设计一个布局，只需添加一个视图，即ImageView，你可以做的就是设计一个你希望服务看起来的布局......和您可以添加ImageView或LinearLayout，而不是添加RelativeLayout。

例如。

private TextView tv;
private RelativeLayout rl;
//code..
//inside your onCreate()
rl = new RelativeLayout(context);
tv = new TextView(context);
tv.setText(badgeCount+"");//Badge Count
rl.addView(floatingFaceBubble);
rl.addView(tv);
//and instead of windowManager.addView(floatingFaceBubble, myParams);
windowManager.addView(rl, myParams);

注意：上面的代码不会按原样运行..但是这里只是为了让您了解如何解决问题。

每当您需要更新Textview的文字时，只需按tv.setText()拨打电话就可以了解您的问题。

//instead of floatingFaceBubble.setOnTouchListener use
rl.setOnTouchListener
//and instead of this windowManager.removeView(floatingFaceBubble); use
windowManager.removeView(rl);
