I want my activity class
to receive an intent from broascast Receiver
(example START_TALKING
, STOP_TALKING
). And when I receive that intent
, I want to check what action was being passed. How can I do this. My receiver is in separate class, it's public
.
Here's my code
public void onReceive(Context context, Intent intent)
{
if (Intent.ACTION_MEDIA_BUTTON.equals(intent.getAction())) {
KeyEvent event = intent.getParcelableExtra(Intent.EXTRA_KEY_EVENT);
switch (event.getKeyCode()) {
case KeyEvent.KEYCODE_HEADSETHOOK:
if (action == KeyEvent.ACTION_DOWN)
// here I want to notify my activity class (e.g. startActivity? I don't know)
break;
case KeyEvent.KEYCODE_MEDIA_PLAY_PAUSE:
// here I want to notify my activity class (e.g. startActivity? I don't know)
}
}
}
I really need your help guys tnx.
Here is my solution, in my project, hope it'll help you:
you should type this:
// put your action string in intent
Intent intent = new Intent("com.example.myproject.ADD_ITEM_BASKET");
// start broadcast
activity.sendBroadcast(intent);
public class Myclass extends Fragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// creating and register receiver
Receiver receiver = new Receiver();
IntentFilter intentFilterAdd = new IntentFilter("com.example.myproject.ADD_ITEM_BASKET");
IntentFilter intentFilterEdit = new IntentFilter("com.example.myproject.DELETE_ITEM_BASKET");
getActivity().registerReceiver(receiver, intentFilterAdd);
getActivity().registerReceiver(receiver, intentFilterDelete);
}
// your receiver class
class Receiver extends BroadcastReceiver
{
// catch messages from intent
@Override
public void onReceive(Context context, Intent intent) {
if("com.example.myproject.ADD_ITEM_BASKET".equals(intent.getAction().toString()))
{
// do something
}
else if("com.example.myproject.DELETE_ITEM_BASKET".equals(intent.getAction().toString()))
{
// do something
}
}
}
}
You have to register the receiver... Follow this example..
public class MyActivity extends Activity {
private BroadcastReceiver myBroadcastReceiver =
new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
// your onreceive code here
}
});
...
public void onResume() {
super.onResume();
....
registerReceiver(myBroadcastReceiver, intentFilter);
}
public void onPause() {
super.onPause();
...
unregisterReceiver(myBroadcastReceiver);
}
...
}
You can use putExtra() in your BroadcastReceiver's onReceive().
/**
* @author Skylifee7 on 23/06/2017.
* TemplateResultReceiver.java
*/
public class TemplateResultReceiver extends BroadcastReceiver {
private static final String TAG = "BleshTemplate";
public static final String EXTRA_MESSAGE = "TRANSACTION_MESSAGE";
Context mContext;
@Override
public void onReceive(Context context, Intent intent) {
mContext = context;
if (intent.getAction().equals(BleshConstant.BLESH_TEMPLATE_RESULT_ACTION)) {
String actionType = intent.getStringExtra(BleshConstant.BLESH_ACTION_TYPE);
String actionValue = intent.getStringExtra(BleshConstant.BLESH_ACTION_VALUE);
if (actionType != null && actionValue != null) {
switch (actionType) {
case "MENU": sendMessage(actionValue);
/*
You may want to increase the case possibilities here, like below:
case: "ADMOB"
case: "VIRTUAL_AVM"
case: "SMART_CAR_KEY"
*/
default: sendMessage(actionValue);
}
}
}
}
private void sendMessage(String actionValue) {
Intent intent = new Intent(mContext.getApplicationContext(),TransactionActivity.class);
intent.putExtra(EXTRA_MESSAGE, actionValue);
mContext.getApplicationContext().startActivity(intent);
}
}
And in your Activity class' onCreate() method:
/**
* @author Skylifee7 on 24/06/2017.
* TransactionActivity.java
*/
public class TransactionActivity extends AppCompatActivity {
private String bleshKey;
private String TAG = "Transaction_Activity";
private String amount;
private String isSuccessful; //may be cast to boolean type.
private double latitude, longitude;
private LocationRequest mLocationRequest;
protected GoogleApiClient mGoogleApiClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_payment);
requestPermission();
initLocationService();
// Get the Intent that started this activity and extract the string
Intent intent = getIntent();
bleshKey = intent.getStringExtra(BleshTemplateResultReceiver.EXTRA_MESSAGE);
ImageButton paymentBtn = (ImageButton) findViewById(R.id.buttonPay);
final EditText editTextAmount = (EditText) findViewById(R.id.editTextAmount);
paymentBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
amount = editTextAmount.getText().toString();
callApiService();
}
});
}
}
