我已经编写了以下代码来向个人发送短信...
Button but = (Button) a;
but.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String messageToSend = "message";
LoginDataBaseAdapter loginDataBaseAdapter = HomeActivity.loginDataBaseAdapter;
car = ((EditText) b ).getText().toString();
String phoneNum=loginDataBaseAdapter.getNum(car);
if(phoneNum !="not") {
SmsManager.getDefault().sendTextMessage(phoneNum, null, messageToSend, null, null);
Toast.makeText(view.getContext(), "MESSAGE SUCCESSFULLY SENT",Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(view.getContext(), "No Car Number found",Toast.LENGTH_SHORT).show();
}
}
});
发送邮件时,我想阻止用户在短时间内向同一用户发送另一条短信,例如禁用but
按钮。谁能帮助我了解如何在一段时间内禁用按钮。
答案 0 :(得分:0)
以下是如何实现此目的的简单方法:
ArrayList<String> sentList = new ArrayList<>();
单击该按钮时,您可以使用方法
将数字或名称添加到ArrayList
sentList.add("Number");
再次点击按钮时,请检查:
for (String string : sentList){
if (!string.equalsIgnoreCase(numberToCheck)) {
//is new number - perform the action
}
}
希望这就是你要找的东西。
修改强>
ArrayList<String> sentNumbers = new ArrayList<>();
Button but = (Button) a;
but.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String messageToSend = "message";
LoginDataBaseAdapter loginDataBaseAdapter = HomeActivity.loginDataBaseAdapter;
car = ((EditText) b ).getText().toString();
String phoneNum = loginDataBaseAdapter.getNum(car);
if(!sentNumbers.isEmpty(){
for (String string : sentList){
if (!string.equalsIgnoreCase(phoneNum)) {
SmsManager.getDefault().sendTextMessage(phoneNum, null, messageToSend, null, null);
sentNumbers.add(phoneNum);
Toast.makeText(view.getContext(), "MESSAGE SUCCESSFULLY SENT",Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(view.getContext(), "No Car Number found",Toast.LENGTH_SHORT).show();
}
}
}else{
SmsManager.getDefault().sendTextMessage(phoneNum, null, messageToSend, null, null);
sentNumbers.add(phoneNum);
}
}
});
清除已使用号码的清单(我想有些事件必须发生?):
sentList.clear();
