Question

我正在尝试发送文本消息一定次数，当我做任何超过100的事情时，它强制关闭应用程序。有什么建议吗？

好的，所以这里是我的更新代码，现在有一些额外的问题 - 吐司永远不会消失，如果我启用我的if语句进行数据验证它将无法工作（基本上是尝试提示用户输入信息，如果它是null而不是仅强制关闭应用程序）

这是我更新的代码：

package net.learn2develop.SMS;

import android.app.Activity;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class MainActivity extends Activity {
EditText PhNumber, Message, TxtCount;
Button btnSendSMS;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    //create text box to enter phone number
    PhNumber=(EditText) findViewById(R.id.PhNumber);

    //create text box to enter message
    Message=(EditText) findViewById(R.id.Message);

    //create text box to see how many times the user wants to send message
    TxtCount=(EditText) findViewById(R.id.TxtCount);

    //create button to send text message
    btnSendSMS = (Button) findViewById(R.id.btnSendSMS);
    //create listener for button
    btnSendSMS.setOnClickListener(new View.OnClickListener()

    {               
        public void onClick(View v)
            {           
                //variable for count.
                int count = 1;
                //variable for text message
                String msg = Message.getText().toString();
                //variable for phone number
                String num = PhNumber.getText().toString();
                //variable for the amount of text messages to send.
                int max = Integer.parseInt(TxtCount.getText().toString());
                //variable to watch button and hide keyboard
                InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);

                //test to see if count has any value at all
                //if (TxtCount.getText().toString().equals(""))
                //{
                //  Toast.makeText(getBaseContext(), "Please enter a number of times to nuke!", Toast.LENGTH_SHORT).show();
                //  return;
                //}
                //test to see if number has a value
                //else if (num.equals(""))
                //{
                //  Toast.makeText(getBaseContext(), "Please enter a phone number to nuke!", Toast.LENGTH_SHORT).show();
                //  return;

                //test to see if there is a message

                //  Toast.makeText(getBaseContext(), "Please enter a message!", Toast.LENGTH_SHORT).show();
                //  return;
                //}             

                //if all fields have valid data -- send text message until count = max                      
                while (count <= max) {                  
                    sendSMS(num, msg);
                    count++;
                };
                //hide the keyboard
                mgr.hideSoftInputFromWindow(TxtCount.getWindowToken(), 0);
                mgr.hideSoftInputFromWindow(PhNumber.getWindowToken(), 0);
                mgr.hideSoftInputFromWindow(Message.getWindowToken(), 0);
                //set phone number to ""

                PhNumber.requestFocus();                    
            }

也许尝试拆分消息，或者通过计时器而不是循环发送消息，你可以尝试这样的事情：

               Thread background = new Thread (new Runnable() {
               public void run() {
                   Thread.sleep(100);
                           // Send message
               }
            });

您可能应该安排服务在每封邮件发送（或失败）时发送广播，然后才发送下一封邮件。你可能正在淹没这项服务，导致部队关闭。

检查the docs如何使用“已发送的意图”。
