我為朋友寫個行車記錄儀後臺循環錄像源碼公開了

說說它實現的原理。

很簡單，就是一個長駐的懸浮窗口。並對窗口進行大小控制。其餘和普通錄像無異。

在不使用相機和嘜的情況下，可以邊上網邊錄像，或者邊打電話邊錄像。

下面直接上碼。

try {

String filePath1 = DirFile.getVideoPath();

DirFile.del_file_by_size(filePath1,

(long) (nc * 1024 * 1024L));

} catch (Exception e) {

//Err.err_ts(e);

}

}

}).start();

}

}

主要實現過程就是這樣，全部放上太長了，還是老方法，放在網盤，供免費下載。可以私信我。

如果對你有幫助，賞個贊。

如果有人支持，我會繼續寫點其他實例，有興趣的關注一下。
