Fetch A Word In Strings Android/Java

So I'm beginning with Android/Java programming. I want to try to find a word in a sentence. Say the user inputs in the EditText a sentence i.e. 'My friend is a cowboy.' The app sho

Solution 1:

Try the following:

String[] words = {"cowboy", "animal", "monster"};
String s = "My friend is a Cowboy";
boolean check = false;

for (int i = 0; i < words.length; i++) {
    if (s.toLowerCase().contains(words[i].toLowerCase())) {
        check = true;
    } else {

    }
}
if (check) {
     System.out.println("Yes");
} else {
     System.out.println("No");
}

Solution 2:

You could try iterating through your array and seeing if the base string contains all of the elements in the array. It would look something like this:

private boolean contains(final String string, final String[] strings){
    for(final String s : strings)
        if(!string.toLowerCase().contains(s.toLowerCase()))
            return false;
    return true;
}

Solution 3:

You can try this. Send from my phon so syntax errors included ;-)

@Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        String string = text.getText().toString();
        boolean hit == false;
        // b = string.indexOf("cowboy") > 0;
        for (int i=0;i<words.length;i++){
            if (string.indexOf(words[i])!=-1){
                hit == true;
                break;
            }
        }
        view.setText(b.toString());
    }
});
