如何从MainActivity调用具有多个操作的IntentService

Question

我必须在Android 8或更高版本上运行代码。

目前我有IntentService的代码如下：

public class MyIntentService extends IntentService {
// TODO: Rename actions, choose action names that describe tasks that this
// IntentService can perform, e.g. ACTION_FETCH_NEW_ITEMS
private static final String ACTION_FOO = "com.example.applocker1.action.FOO";
private static final String ACTION_BAZ = "com.example.applocker1.action.BAZ";
// TODO: Rename parameters
private static final String EXTRA_PARAM1 = "com.example.applocker1.extra.PARAM1";
private static final String EXTRA_PARAM2 = "com.example.applocker1.extra.PARAM2";
public MyIntentService() {
super("MyIntentService");
}
/**
* Starts this service to perform action Foo with the given parameters. If
* the service is already performing a task this action will be queued.
*
* @see IntentService
*/
// TODO: Customize helper method
public static void startActionFoo(Context context, String param1, String param2) {
Intent intent = new Intent(context, MyIntentService.class);
intent.setAction(ACTION_FOO);
intent.putExtra(EXTRA_PARAM1, param1);
intent.putExtra(EXTRA_PARAM2, param2);
context.startService(intent);
}
/**
* Starts this service to perform action Baz with the given parameters. If
* the service is already performing a task this action will be queued.
*
* @see IntentService
*/
// TODO: Customize helper method
public static void startActionBaz(Context context, String param1, String param2) {
Intent intent = new Intent(context, MyIntentService.class);
intent.setAction(ACTION_BAZ);
intent.putExtra(EXTRA_PARAM1, param1);
intent.putExtra(EXTRA_PARAM2, param2);
context.startService(intent);
}
@Override
protected void onHandleIntent(Intent intent) {
if (intent != null) {
final String action = intent.getAction();
if (ACTION_FOO.equals(action)) {
final String param1 = intent.getStringExtra(EXTRA_PARAM1);
final String param2 = intent.getStringExtra(EXTRA_PARAM2);
handleActionFoo(param1, param2);
} else if (ACTION_BAZ.equals(action)) {
final String param1 = intent.getStringExtra(EXTRA_PARAM1);
final String param2 = intent.getStringExtra(EXTRA_PARAM2);
handleActionBaz(param1, param2);
}
}
}
/**
* Handle action Foo in the provided background thread with the provided
* parameters.
*/
private void handleActionFoo(String param1, String param2) {
// TODO: Handle action Foo
Log.i("In Service : ", "Action Foo");
throw new UnsupportedOperationException("Not yet implemented");
}
/**
* Handle action Baz in the provided background thread with the provided
* parameters.
*/
private void handleActionBaz(String param1, String param2) {
// TODO: Handle action Baz
Log.i("In Service : ", "Action Baz");
throw new UnsupportedOperationException("Not yet implemented");
}
}

如何从主活动中操作ACTION_FOO和ACTION_BAZ？

Answer 1

要在MainActivity中启动操作FOO，请执行以下操作：

MyIntentService.startActionFoo(this, param1, param2);

要在MainActivity中启动BAZ操作，请执行以下操作：

MyIntentService.startActionBaz(this, param1, param2);
