[英]String comparison not working (android)
我的字符串比较不起作用。 我不知道为什么。 即使两个字符串不相同,它也会返回它总是相等的
这是我使用的代码
if(videoFile.equals(LangSelect.INSTRUCTION_01));
{
Log.i("InstructionVideo", "video and instruction are equal\n"+ videoFile + "\n" + LangSelect.INSTRUCTION_01);
//hideBackButton();
}
videoFile是intro_x.mp4,其中x从0变为4,而INSTRUCTION_01是into_0.mp4
我的onCreate的一部分确实设置了videoFile变量
//get which video file to play
videoFile = getIntent().getExtras().getString("PlayVideo");
Log.i("InstructionVideo", "videoFile name: " +videoFile);
这是该部分的LogCat

它表明,即使我比较它们,它们返回真实但不是
有一个;
在“if”行的末尾,它终止“if”语句,因此始终执行以下块。
