activity 与service 的广播

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.common_down_layout);
        AppManager.appManager.getActivities().add(this);
        backBtn = (Button) this.findViewById(R.id.back_btn);
        backBtn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                finish();
            }
        });
        receiver = new UpdateReceiver();
        receiver.registerAction(AppConstant.LocalActivityConstant.update_action);

class UpdateReceiver extends BroadcastReceiver
    {
        
        public void registerAction(String action)
        {
            IntentFilter intentFilter = new IntentFilter();
            intentFilter.addAction(action);

public class LocalActivityConstant
	{
		public static final String update_action="updateUI";
		public static final String update_down_done_action = "done_updateui";
	}

service类发送广播    
Intent intent = new Intent();
                intent.setAction(AppConstant.LocalActivityConstant.update_action);
                intent.putExtra("completeSize", size);
                intent.putExtra("url", url);
                mContext.sendBroadcast(intent);

 

　　

registerReceiver(this, intentFilter); } @Override public void onReceive(Context context, Intent intent) { //接收来自DownloadService传送过来的数据,并且更新进度条 if(intent.getAction().equals(AppConstant.LocalActivityConstant.update_action)) { String url=intent.getStringExtra("url"); int completeSize = intent.getIntExtra("completeSize", 0); adapter.setPercents(url, completeSize); } } }

 

    }
