如何记录android点击事件背景
我想在使用其他应用程序时记录android点击事件。对于每次单击,我都会记录其时间戳。所以,这个应用程序应该在后台运行。我使用“getevent”捕捉单击事件。我对安卓操作不是很熟悉。我的代码 他有一只虫子。它的输出不是很好,输出中有许多“null”,并且记录不完全正确。(我的应用程序需要root权限) 1.MainActivity.java如何记录android点击事件背景,android,Android,我想在使用其他应用程序时记录android点击事件。对于每次单击,我都会记录其时间戳。所以,这个应用程序应该在后台运行。我使用“getevent”捕捉单击事件。我对安卓操作不是很熟悉。我的代码 他有一只虫子。它的输出不是很好,输出中有许多“null”,并且记录不完全正确。(我的应用程序需要root权限) 1.MainActivity.java package kingofne.seu.edu.ndktest; import android.content.Intent; import andr
