如何在Android中发送短信

Question

我正在使用短信开发应用程序，我的要求是1）发送具有静态值的短信2）每当我们单击编辑按钮时，我们都可以更改值并发送短信，我可以成功完成这两个操作，但是我的第三个要求是仅发送短信当单击编辑和更改值时，单击提交按钮，而没有更改值，我不希望发送短信。 我想当单击编辑按钮时仅发送短信，我尝试了if（editBtn.isSelected），但它不起作用。 请告诉任何解决方案

我的代码是

Answer 1

尝试对编辑文本使用OnTouchListener

样品，

  editBtn.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub

                           changeEdit();

            return true;
        }
    });

如果它不起作用

在全局范围内创建一个布尔变量，如果您触摸了edittext，则将其设为true，

//在杂种

 boolean e_clicked = false;

//在Edittext的onTouchListener内部

 e_clicked=true;

并检查

 if(e_clicked)
 {
 // your sms send action
 }

尝试这个

     public class AlarmReceiver extends BroadcastReceiver {
    public void onReceive(Context context, Intent intent) {
    @Override
    public void onReceive(Context context, Intent intent) {
    Intent intent=new Intent(context,Service.class);
    //get lat/lng and pass it or get from service if u want
    intent.putExtra("lat","lat");
    intent.putExtra("lon","lng");
    context.startService(intent);

}  
    }

    public void SetAlarm(Context context) {

        AlarmManager am = (AlarmManager) context
                .getSystemService(Context.ALARM_SERVICE);
        Intent i = new Intent(context, AlarmReceiver.class);
        PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0);
         Calendar calendar = Calendar.getInstance();

           calendar.setTimeInMillis(System.currentTimeMillis());

           calendar.add(Calendar.MINUTE, 10);
           am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),
                calendar.getTimeInMillis(), pi);
    }
