Question

我有两个字符串字符串1 =“奉上帝的仁慈仁慈的名义。” 字符串2 =“以仁慈的上帝的名义”

我想将字符串2的每个单词与字符串1匹配。我使用了下面的代码，但在上述情况下无法正常工作

 private void printDiff(final Context context, String sentence1, String sentence2) {
        String[] array1 = sentence1.split(" ");
        String[] array2 = sentence2.split(" ");

        SpannableStringBuilder sb = new SpannableStringBuilder(sentence1);
        for (int i = 0; i < array1.length; i++) {
            int colorRes;
            if (i < array2.length) {

                    colorRes = array1[i].equalsIgnoreCase(array2[i]) ? R.color.colorPrimary : R.color.colorAccent;


            } else {
                colorRes = R.color.black;
            }
            int startIndex = getStartIndexOf(array1, i);
            int endIndex = startIndex + array1[i].length();
            sb.setSpan(new ForegroundColorSpan(ContextCompat.getColor(context, colorRes)), startIndex, endIndex, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
        }


    } 

 public static int getStartIndexOf(String[] array, int index) {
        int count = 0;
        for (int i = 0; i < index; i++) {
            count += array[i].length();
            count++;
        }
        return count;
    }

谁能帮我

我想要这样的输出。因为所有字符都匹配

Answer 1

您可以将String转换为字符数组，并可以按字符进行匹配

s1 = s1.replacereplace(" ", "");
s1 = s1.replacereplace(",", "");

s2 = s2.replacereplace(" ", "");

  char[] a = s1.toCharArray(); 

  char[] b = s2.toCharArray();
  int j=0;
   for(int i=0; <a.length; i++){
        if(a[i]==b[j]){

         }
           j++;
    }

尝试使用此代码来检查您的字符串的差异

public class TestActivity extends AppCompatActivity {

    String string1 = "In the name of God, the Gracious, the Merciful.";
    String string2 = "In the name of God the Gracious the mercifuls";

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);

        List<String> stringList = new ArrayList<>(Arrays.asList(string2.split(" "))); // Split the string into list
        // compare the list with the source of the string, if match put into the list of result
        List<String> result = stringList.stream().filter(new Predicate<String>() {
            @Override
            public boolean test(String s) {
//                return string1.contains(s); // case sensitive
                return Pattern.compile(Pattern.quote(s), Pattern.CASE_INSENSITIVE).matcher(string1).find(); // case insensitive
            }
        }).collect(Collectors.toList());

        // check the match results
        if(result.size()<stringList.size()){
            Log.d("test", "onCreate: not match");
        }else{
            Log.d("test", "onCreate: match");
        }
    }
}

希望可以帮助您解决问题

因此可以使用上面的代码来编辑gradle。打开您的app.gradle并将其放入gradle

android {
    compileSdkVersion 28
    defaultConfig {
        .....
    }
    buildTypes {
        release {
            .....
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

}
