我已经设置好了，当用户点击“打卡”时，它会启动 IntentService，然后 Intent 服务会更新 UI，唯一的问题是它不工作....这是我的主要活动页面代码：
package com.famousmods.payme;

import java.util.TimerTask;
import android.os.Bundle;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;

public class PayTracker extends Activity {

private static double Reserve;
private static int Reserve1;
public static double money;
public static double counter;
private static int go;
private static int countdown;
public static int convert;
public static double HW;
public static double OTW;
public static double HPD;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pay_tracker);
getActionBar().setDisplayHomeAsUpEnabled(true);
// register reciver
IntentFilter filter = new IntentFilter(ResponseReceiver.ACTION_RESP);
filter.addCategory(Intent.CATEGORY_DEFAULT);
receiver = new ResponseReceiver();
registerReceiver(receiver, filter);
// Receive messages from options page
double pHW, pOTW, pHPD;
Intent intent = getIntent();
pHW = intent.getDoubleExtra(Options.MESSAGE_HW, 0);
pOTW = intent.getDoubleExtra(Options.MESSAGE_OTW, 0);
pHPD = intent.getDoubleExtra(Options.MESSAGE_HPD, 0);
if(pHW != 0){
HW = pHW;
OTW = pOTW;
HPD = pHPD;
}
// Color buttons
Button buttonc = (Button) findViewById(R.id.clockin);
buttonc.getBackground().setColorFilter(0xFF00FF00, PorterDuff.Mode.MULTIPLY);
Button buttond = (Button) findViewById(R.id.clockout);
buttond.getBackground().setColorFilter(0xFFFF0000, PorterDuff.Mode.MULTIPLY);
final Button b = (Button) findViewById(R.id.clockout);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_pay_tracker, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
};
return super.onOptionsItemSelected(item);
}
public void sendMessage(View view) {
//Start IntentService
Intent msgIntent = new Intent(this, SimpleIntentService.class);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_HW, HW);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_OTW, OTW);
msgIntent.putExtra(SimpleIntentService.PARAM_IN_HPD, HPD);
startService(msgIntent);//}
}
public class ResponseReceiver extends BroadcastReceiver {
public static final String ACTION_RESP = "com.famousmods.payme.action.MESSAGE_PROCESSED";
@Override
public void onReceive(Context context, Intent intent) {
// Update UI, new "message" processed by SimpleIntentService
final TextView t1 = (TextView) findViewById(R.id.yourpay);
t1.setTextColor(Color.parseColor("#008000"));
final TextView t2 = (TextView) findViewById(R.id.payper);
String end = intent.getStringExtra(SimpleIntentService.PARAM_OUT_END);
String result = intent.getStringExtra(SimpleIntentService.PARAM_OUT_RESULT);
t2.setText(result);
t1.setText(end);
}
}
@Override
public void onDestroy() {
this.unregisterReceiver(receiver);
super.onDestroy();
}
}
这是我的意图服务页面，它的设置是为了在意图启动时启动一个计时器，每 20 毫秒应该将新意图发送回活动页面，这是代码：
package com.famousmods.payme;
import java.util.Timer;
import java.util.TimerTask;
import com.famousmods.payme.PayTracker.ResponseReceiver;
import android.app.IntentService;
import android.content.Intent;
public class SimpleIntentService extends IntentService {
public static final String PARAM_OUT_END = "end";
public static final String PARAM_OUT_RESULT = "result";
public static final String PARAM_IN_HW = "hourly wage";
public static final String PARAM_IN_OTW = "overtime";
public static final String PARAM_IN_HPD = "hours per day";
public static String end;
public static String result;
private static double Reserve;
private static int Reserve1;
public static double money;
public static double counter;
private static int go;
private static int countdown;
public static int convert;
public SimpleIntentService() {
super("SimpleIntentService");
}
@Override
protected void onHandleIntent(Intent intent) {
// recieve from paytracker
double HW = intent.getDoubleExtra(PARAM_IN_HW, 1);
double OTW = intent.getDoubleExtra(PARAM_IN_OTW, 1);
double HPD = intent.getDoubleExtra(PARAM_IN_HPD, 1);
// Calculate pay per second
final double PPS = (HW/3600);
final double DPPS = (PPS/50);
final double OTPPS = (OTW/3600);
final double DOTPPS = (OTPPS/50);
final double HPDPS = (HPD*3600);
final double DHPDPS = (HPDPS*50);
Timer t = new Timer();
t.schedule(new TimerTask() {
@Override
public void run() {
new Runnable() {
public void run() {
if(DHPDPS==0){
money = (DPPS+Reserve);
Reserve = (money);
end = String.format("%1f", money);
//t1.setText("$" + end);
}else if(counter > DHPDPS && DOTPPS != 0 && DHPDPS != 0){
money = (DOTPPS+Reserve);
Reserve = (money);
end = String.format("%1f", money);
//t1.setText("$" + end);
} else{
money = (DPPS+Reserve);
Reserve = (money);
end = String.format("%1f", money);
//t1.setText("$" + end);
}
counter++;
//if(counter == 3000)
// t.cancel();
// Display pay per second
if(counter <= DHPDPS || DHPDPS == 0){
result = String.format("%.8f", PPS);
}else{
// t2.setText("Your pay per second is: $"+result2);
result = String.format("%.8f", OTPPS);
}
// Broadcast intent
Intent broadcastIntent = new Intent();
broadcastIntent.setAction(ResponseReceiver.ACTION_RESP);
broadcastIntent.addCategory(Intent.CATEGORY_DEFAULT);
broadcastIntent.putExtra(PARAM_OUT_END, end);
broadcastIntent.putExtra(PARAM_OUT_RESULT, result);
sendBroadcast(broadcastIntent);
}
};
}
}, 20, 20);
}
}
谢谢大家！
