Question

我实施了很多方法但没有获得所需的结果。我想在Android中的单击按钮上调用2个方法。

我尝试下面的代码，但它对我不起作用。

 @Override
public void onClick(View v) {
 // TODO Auto-generated method stub
 switch (v.getId()) {

 case R.id.savebtn:   

   startAlert(); 

 default:
  break;
 }

}


 public void startAlert() {          

        EditText Start_alarm = (EditText) findViewById(R.id.timeout_et);  
        int i = Integer.parseInt(Start_alarm.getText().toString());  

        Intent intent = new Intent(this, MyBroadcastReceiver.class);  
        PendingIntent pendingIntent = PendingIntent.getBroadcast(  
                                      this.getApplicationContext(), 234324243, intent, 0);  
        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);  
        alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()  
                                      + ((i * 1000)*60), pendingIntent);  
        Toast.makeText(this, "Alarm set in " + i + " minute",Toast.LENGTH_LONG).show();  

        // App Exit here
        Intent intent_exit = new Intent(Intent.ACTION_MAIN);
        intent_exit.addCategory(Intent.CATEGORY_HOME);
        intent_exit.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent_exit);
        finish();

        SetUpdateInterval();

    }

    //-------Repeating Video--------- 
 private void SetUpdateInterval() {
    // TODO Auto-generated method stub
     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);  
     Intent intent = new Intent(this, MyBroadcastReceiver.class);  

     PendingIntent pendingIntent = PendingIntent.getBroadcast(  
             this.getApplicationContext(), 234324243, intent, 0); 
     EditText update_time = (EditText) findViewById(R.id.updateinterval_et); 
     int j = Integer.parseInt(update_time.getText().toString());  
     Calendar calendar = Calendar.getInstance();
     calendar.setTimeInMillis(System.currentTimeMillis());          
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60 * j, pendingIntent);

}

现在，使用此代码只调用一个方法，即StartAlert（）。我也想调用SetUpdateInterval方法。那么任何人都可以告诉我，我如何同时运行这两种方法。

提前谢谢。

简化代码

    @Override
public void onClick(View v) {
 // TODO Auto-generated method stub
 switch (v.getId()) {   
 case R.id.savebtn:

   startAlert(); 
   SetUpdateInterval();

    finish();            
     break;

      case R.id.cancelbtn:
  finish();
        break;

 default:
  break;
 }
}

 public void startAlert() {  

        int i = Integer.parseInt(timeout_et.getText().toString());  
        System.out.println("VAlue of i" +" "+i);

        int j = Integer.parseInt(update_et.getText().toString());  

        Intent intent = new Intent(this, MyBroadcastReceiver.class);  
        PendingIntent pendingIntent = PendingIntent.getBroadcast(  
                                      this.getApplicationContext(), 234324243, intent, 0);  
        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);  
        alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()  
                                      + ((i * 1000)*60), pendingIntent); 
        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()  
                + ((j * 1000)*60), j, pendingIntent); 
        Toast.makeText(this, "Alarm set in " + i + " minute",Toast.LENGTH_LONG).show();  

      }

   //-------Repeating Video--------- 
     private void SetUpdateInterval() {

         AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);  
         Intent intent = new Intent(this, MyBroadcastReceiver.class);  

         PendingIntent pendingIntent = PendingIntent.getBroadcast(  
                 this.getApplicationContext(), 234324243, intent, 0); 
         EditText update_time = (EditText) findViewById(R.id.updateinterval_et); 
         int j = Integer.parseInt(update_time.getText().toString());  
         Calendar calendar = Calendar.getInstance();
         calendar.setTimeInMillis(System.currentTimeMillis());          
         alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000 * 60 * j, pendingIntent);

       // App Exit here
       Intent intent_exit = new Intent(Intent.ACTION_MAIN);
       intent_exit.addCategory(Intent.CATEGORY_HOME);
       intent_exit.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
       startActivity(intent_exit);
       finish();

 }

Answer 1

在开始其他活动并完成当前活动之前调用SetUpdateInterval()方法。

Answer 2

只需替换下面的代码，您就可以在调用该方法之前完成活动：

    @Override
public void onClick(View v) {
 // TODO Auto-generated method stub
 switch (v.getId()) {

 case R.id.savebtn:   

   startAlert(); 
   SetUpdateInterval()

 default:
  break;
 }

}

//将下面的代码放在SetUpdateInterval（）方法中一段延迟，然后完成。

new Timer().schedule(new TimerTask() {

    @Override
    public void run() {
        finish();

    }
},3000);

如何在android中单击按钮调用多个方法？`
