Android字符串不等于
|
我是Java和Android的新手，所以我相信这将是一个简单的问题/答案。我知道要找出一个字符串是否等于另一个字符串，可以使用equal函数。在我的情况下，我正在扫描QR码，扫描结果类似于\“ EMPLOYEE ~~ John Smith ~~ DIVISION ~~ Maintenance \”。我需要知道如何执行以下操作：
String contents = intent.getStringExtra(\"SCAN_RESULT\");
// I know that \"contents\" contains the string \" EMPLOYEE~~John Smith~~DIVISION~~Maintenance\"
String[] myJunk = contents.split(\"~~\");
// This should split everything up into an array named myJunk (right)?
String val1 = myJunk[0];
// Now val1 Should be equal to \"EMPLOYEE\"
if (myJunk[0].equals(val1)){
// Do Something
}
没有找到相关结果

String contents = \"EMPLOYEE~~John Smith~~DIVISION~~Maintenance\"; String[] myJunk = contents.split(\"~~\"); // This should split everything up into an array named myJunk (right)? String val1 = myJunk[0]; Toast.makeText(this, \"val1 = \"+val1, Toast.LENGTH_LONG).show(); Toast.makeText(this, \"val2 = \"+myJunk[1], Toast.LENGTH_LONG).show(); // Now val1 Should be equal to \"EMPLOYEE\" if (myJunk[0].equals(val1)){ Toast.makeText(this, \"equals\", Toast.LENGTH_LONG).show(); }体悉
因此，拆分后，myJunk [0]将包含（请注意单词EMPLOYEE前面的空格）。 因此，在进行比较之前，您需要调整值桑娠贯涤
String contents = intent.getStringExtra(\"SCAN_RESULT\"); // I know that \"contents\" contains the string \" EMPLOYEE~~John Smith~~DIVISION~~Maintenance\" System.out.println(\"contents is \"+contents ); String[] myJunk = contents.split(\"~~\"); // This should split everything up into an array named myJunk (right)? System.out.println(\"Array size is \"+myJunk.length); String val1 = myJunk[0]; // Now val1 Should be equal to \"EMPLOYEE\" for(int i=0; i < myJunk.length; i++) { System.out.println(\"String \"+i+ \"in array is: \"+myJunk[i]); } //Here i run through the array and print every element. if (myJunk[0].equals(val1)){ // Do Something }
