效果圖如下:
實(shí)現(xiàn)當(dāng)前這種類似的效果 (360小球 懸浮桌面差不錯(cuò)類似)。第一次接觸到的童鞋就像我一樣懵逼(研究過得童鞋晌梨,就知道歹苦,實(shí)現(xiàn)這種懸浮窗體监右,是需要添加懸浮窗 設(shè)置權(quán)限的,我會在下篇文章進(jìn)行公開源碼)廢話不多說 潦牛,直接上代碼眶掌。
1.新建工程,添加懸浮窗權(quán)限巴碗。
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
2.自定義一個(gè)FloatMessagerMainWindow

- 調(diào)用方法:
FloatMessagerMainWindow.getFloatMessagerMainWindow(context, null);
實(shí)現(xiàn)到此 朴爬,點(diǎn)擊按鈕就可以實(shí)現(xiàn) 懸浮窗。(此處可能會出現(xiàn)相應(yīng)的崩潰良价,崩潰原因是懸浮窗的 懸浮權(quán)限開啟問題。)
4.我以官方模擬器為例開啟懸浮權(quán)限(找不到此位置的 在下方留言):
此時(shí)再次打開工程蒿叠,點(diǎn)擊按鈕明垢,就可以實(shí)現(xiàn)懸浮效果。
后期我將公布代碼鏈接(關(guān)于 拖動懸浮窗體市咽,改變位置痊银,懸浮權(quán)限的多品牌的手機(jī)適配)
