尝试发送文本消息超过100次，有没有办法覆盖SMSDispatcher文本限制？
这是错误：

答案 0 :(得分：0)
您无法将字符串与==进行比较 试试这个
if (TxtCount.getText().toString().equals(""))
{
Toast.makeText(getApplicationContext(), "Please enter a number of times to nuke!", Toast.LENGTH_SHORT).show();
}
else if (num.queals(""))
{
Toast.makeText(getApplicationContext(), "Please enter a phone number to nuke!", Toast.LENGTH_SHORT).show();
}
else if (msg.equals(""))
{
Toast.makeText(getApplicationContext(), "Please enter a message!", Toast.LENGTH_SHORT).show();
}
while (count <= max)
{
sendSMS(""+num,""+ msg);
count++;
};
喜欢这个
else if (num.equals(""))
{
Toast.makeText(getApplicationContext(), "Please enter a phone number to nuke!", Toast.LENGTH_SHORT).show();
return;
}
