android限制edittext最大行数的方法

getInputView().addTextChangedListener(new TextWatcher() {
String currentText = "";

@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}

@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
}

@Override
public void afterTextChanged(Editable s) {
int lines = getInputView().getLineCount();
// 限制最大输入行数
if (lines > getInputView().getMaxLines()) {
getInputView().setText(currentText);
getInputView().setSelection(currentText.length());
} else if (lines <= getInputView().getMaxLines()) {
currentText = s != null ? s.toString() : "";
}
}
});

android:lines="3"
或者
android:maxLines="3"
来限制
