我正在创建一个应用程序来向人们发送X数量的文本,在重新编写我的代码以包含线程之后,它就破了。还有," Thread.sleep(3000);"部分代码冻结了UI,或者我的所有代码都在线程中解决了这个问题?最后一个问题,我如何防止脚本在后台停止(继续发送)

public abstract class multisender2 extends Activity implements Runnable {
    @Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
    public void csend(View view) {
     EditText number = (EditText)findViewById(R.id.pnumber);
     EditText message = (EditText)findViewById(R.id.pmessage);
     EditText hmany = (EditText)findViewById(R.id.hmany);
     String _hmany = hmany.getText().toString();
     final String _number = number.getText().toString();
     final String _message = message.getText().toString();
     final int xtime = Integer.parseInt(_hmany);
     final int count = 1;
    Thread background = new Thread(new Runnable() { 

@Override
public void run() {
    try {
    if (count > xtime == false){
    SmsManager.getDefault().sendTextMessage(_number, null, _message, null, null);
        Thread.sleep(3000);
              }
    } catch (InterruptedException e) {
 }
 }

});       
    background.start();
}
}

谢谢,这是LogCat

不要阻止 ma 线程。尝试使用AsyncTask。有关详细信息,请参阅 - Processes and Threads
