如何从一个EditText获取多个变量？

Question

I'm looking for a way to get three float values from one EditText.I've Looked of the developers page but i couldnt find anything that best fit my need.I would like to get three floats ax,y,z from one entry of EditText?

Thank you guys so much on the replys o this Question im really greatfull. Im limited to the time on my computer right now but ill let you know which answer work for me and ill post my code too.

Answer 1

If they are separated by whitespaces

Scanner sc = new Scanner(yourEditText.getText().toString());

float vals = new float[3];

while(int i=0; sc.hasNextFloat() && (i < 3); ++i) {
   vals[i] = sc.nextFloat();
}

otherwise use Scanner.setDelimiter to set delimiter(s) other than whitespaces.

Reconsider your design to use three EditTexts instead. On mobile phones it's a pain to enter symbols like comma

Answer 2

String value = yourEditText.getText().toString();
String[] floatStrings = value.split(",");
float[] result = new float[floatString.length];
for (int i=0; i<result.length; i++) {
    result[i] = Float.valueOf(floatStrings[i];
}

?

Answer 3

如果希望用户输入3个单独的值，则将使用3个EditText小部件，这些值将被解析为3个单独的变量。

Answer 4

You should either create several EditText views, or then parse the contents of the EditText

EditText textView;

String[] splitFloatStrings = textView.getText().toString();.split(",");
float[] parsedFloats = new float[splitFloatStrings.length];

for (int i=0; i < parsedFloats.length; i++) {
    parsedFloats[i] = Float.valueOf(splitFloatStrings[i];
}

As per Java parsing a string of floats to a float array?
