我想使用意图将代码 *777# 发送到 android 中的拨号器,但我有一个问题只有 *777 密钥代码将显示在拨号器上而不是 # 如何解决这个问题我是 android 开发人员的新手,所以请帮我解决这个问题.
String dialler_Code = "*777#";
Toast.makeText(this, "clicked", Toast.LENGTH_LONG)
.show();
// Use format with "tel:" and phoneNumber created is stored in u.
Uri u = Uri.parse("tel:" + dialler_Code);
// Create the intent and set the data for the intent as the phone number.
Intent i = new Intent(Intent.ACTION_DIAL, u);
try {
// Launch the Phone app's dialer with a phone number to dial a call.
startActivity(i);
} catch (SecurityException s) {
// show() method display the toast with exception message.
Toast.makeText(this, s.getMessage() , Toast.LENGTH_LONG)
.show();
}
