在EditText变量

中获取String个文字

String finalString = "";
String textToShow = sampleEditText.getText().toString();
if (textToShow.length > 23) {
    finalString = textToShow.substring(0,23) + "\n" + textToShow.substring(23);
}
else {
    finalString = textToShow;
}
//then set finalString for your textview

textViewDisplay.setText(finalString);

Answer 2

试试这个。

android:maxLines="2"

Answer 3

试试这个：

String your_data="abcdef......";
String value=setText(your_data);
textView.setText(value);

setText方法：

public String setText(String text){

    String lineString = "";
    while (text.length() > 23) {

        String buffer = text.substring(0, 23);
        lineString = lineString + buffer + "/n";
        text = text.substring(23);
    }

    lineString = lineString + text.substring(0);
    return lineString;
}
