我向你们寻求一个程序的帮助,似乎它会起作用.如果我能让线程/ asynctask工作.我已经尝试过使用线程,但我没有让它工作.我试图进行线程化的原因是因为我的程序在加载时崩溃了,基本上它假设要做的是发送电子邮件,如果有人正在打电话,因为我总是错放我的手机或者保持静音,我我不知道.
服务-
@H_502_7@ public class Callservice extends Service {
PhoneStateListener listener;
TelephonyManager tm;
@Override
public void onCreate()
{
Toast.makeText(getApplicationContext(),"Service has started",Toast.LENGTH_LONG).show();
listener = new MyphoneStateListener();
tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
tm.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);
}
public class MyphoneStateListener extends PhoneStateListener
{
public void onCallStateChanged(int state,String incomingNumber)
{
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
break;
case TelephonyManager.CALL_STATE_RINGING:
sendemail();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
default:
break;
}
super.onCallStateChanged(state,incomingNumber);
}
}
private void sendemail()
{
Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL,new String[]{"random@gmail.com"});
i.putExtra(Intent.EXTRA_SUBJECT,"phone is ringing");
i.putExtra(Intent.EXTRA_TEXT,"email successfully sent");
startActivity(Intent.createChooser(i,"send mail..."));
Toast.makeText(getApplicationContext(),"Email has been sent",Toast.LENGTH_LONG).show();
try
{
startActivity(Intent.createChooser(i,"Send Email..."));
}
catch(android.content.ActivityNotFoundException ex)
{
}
}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
}
活动-
@H_502_7@public class MainActivity extends Activity {
Callservice callservice = new Callservice();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
callservice.onCreate();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main,menu);
return true;
}
}
最佳答案
更改MainActivity活动以及从Activity启动Service：
@H_502_7@
public class MainActivity extends Activity {
//Callservice callservice = new Callservice();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this,Callservice.class));
}
// your code here...
并确保您已在AndroidManifest.xml中添加了您的服务：
@H_502_7@
