Android中的NumberPicker水平显示的问题

Question

Android中的NumberPicker是垂直显示的,上面有增加和减少的按钮，下面显示数字。是否有办法让NumberPicker水平显示吗?让按钮在左边显示，右边显示数字。

Answer 1

valueText.addTextChangedListener(new TextWatcher() {

private int backupValue;

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

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

@Override
public void afterTextChanged(Editable s) {
String string = s.toString().trim();
if(string.equals("")) {
setValue(1);
return;
}
try {
value = Integer.parseInt(s.toString());
if(value > MAXIMUM) {
setValue(MAXIMUM);
}
} catch( NumberFormatException nfe ){
setValue(backupValue);
}
}

});
