如何在字符串数组中搜索和替换整个短语？

Question

I am trying to search a string for a phrase of words, and then replace the phrase with a blank space. Here is my code:

  public void convertToNotes() {
    classNotes = (EditText) findViewById(R.id.class_notes);
    className = (EditText) findViewById(R.id.class_name);
    verifyTextView = (TextView) findViewById(R.id.textView);
    verifyTextView.setSingleLine(false);

    conversionText = classNotes.getText().toString();
    String[] result = conversionText.split(".");


    for (int a = 0; a < result.length; a++) {

        result[a] = result[a].replaceAll("forget"+ "about"+ "that", "");
        result[a] = result[a].replaceAll("important", " <br><u>IMPORTANT</u>");
        }
    verifyTextView.setText(Html.fromHtml(Arrays.toString(result)));
 }

I have also tried :

result[a] = result[a].replaceAll("forget about that", "");

But the phrase is still not removed.

You don't need to split your string in order to replace elements. You can do something like:

conversionText = conversionText.replaceAll("forget" /*or other regex*/, "");
verifyTextView.setText(Html.fromHtml(conversionText));

If you need to keep the splitting for some reason and If you have troubles with regex, take a look here .
