让你的 textView 支持多行，然后在代码中创建一个 StringBuffer 并将结果附加到它上面，比如

resultString.append(result).append(" appeared").append(c).append(" times\n");

之后，您为 textView 设置文本，例如：

textView.setText(resultString.toString());

这是想法：

    // this is test string, you can read it from your textView
    String []values = ( "2, 1, 3, 5, 1, 2".toString().split(","));
    int [] intValues = new int[values.length];
    // convert string values to int
    for (int i = 0; i < values.length; ++i) {
        intValues[i] = Integer.parseInt(values[i].trim());
    }

    // sort integer array
    Arrays.sort(intValues);

    StringBuilder output = new StringBuilder();
    // iterate and count occurrences
    int count = 1;
    // you don't need internal loop, one loop is enough
    for (int i = 0; i < intValues.length; ++i) {
        if (i == intValues.length - 1 || intValues[i] != intValues[i + 1]) {
            // we found end of "equal" sequence
            output.append(intValues[i] + " appeared " + count + " times\n");
            count = 1; // reset count
        } else {
            count++; // continue till we count all equal values
        }
    }

    System.out.println(output.toString()); // prints what you extected
    table.setText(output.toString()); // display output
