我正在开发一个应用程序，我想在其中设置美国格式的电话号码，例如 xxx-xxx-xxxx。我怎样才能做到这一点？
最佳答案
尝试实现下面的代码然后你会在输入数字时得到“-”
text.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
boolean flag = true;
String eachBlock[] = text.getText().toString().split("-");
for (int i = 0; i < eachBlock.length; i++)
{
if (eachBlock[i].length() > 3)
{
Log.v("11111111111111111111","cc"+flag + eachBlock[i].length());
}
}
if (flag) {
text.setOnKeyListener(new OnKeyListener() {
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DEL)
keyDel = 1;
return false;
}
});
if (keyDel == 0) {
if (((text.getText().length() + 1) % 4) == 0)
{
if (text.getText().toString().split("-").length <= 2)
{
text.setText(text.getText() + "-");
text.setSelection(text.getText().length());
}
}
a = text.getText().toString();
}
else
{
a = text.getText().toString();
keyDel = 0;
}
} else {
text.setText(a);
}
}
public void beforeTextChanged(CharSequence s, int start, int count,int after)
{
}
public void afterTextChanged(Editable s) {
}
});
