Qr scanner scanned result in fragment

Qr scanner scanned result in fragment - java

I am beginner to android..I integrated qr scanner ZXING library in my app..in fragment layout..this library working..On click button..qr scanner is opening..but scanned result is not displaying inside edit text in fragment layout..how to display result in fragment?
below is my On click button code
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = null;
view = inflater.inflate(R.layout.configure_switch,container,false);
button = (Button)view.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
IntentIntegrator integrator = new IntentIntegrator(getActivity());
integrator.initiateScan();
}
});

it's simple. after getting scanned result, you need to put the following code.
YourEditTextName.setText(ResultText);

Happy coding.!!!

when you receive the result to a activity get the current fragment and call that method like below
CustomFragmentClass will be your fragment.
Fragment fragment = getActivity().getFragmentManager().findFragmentById(R.id.fragment_container);
if (fragment instanceof CustomFragmentClass){
fragment.onActivityResult(int requestCode, int resultCode, Intent data);
}
or you can also refer this onActivityResult is not being called in Fragment

How can I save user messages and history to room database

I am developing a chat app and I want to save user chat history and messages using room database. By this, when the users start the app they can see their previous history and messages.
Below my User.java model class where implemented user model properties.
#Entity
public class User implements IChatUser {
#PrimaryKey(autoGenerate = true)
private Integer id;
#ColumnInfo(name = "name")
String name;
#Ignore
Bitmap icon;
public User() {
}
public User(int id, String name, Bitmap icon) {
this.id = id;
this.name = name;
this.icon = icon;
}
#Override
public String getId() {
return this.id.toString();
}
#Override
public String getName() {
return this.name;
}
public void setId(Integer id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
#Override
public Bitmap getIcon() {
return this.icon;
}
#Override

You should create a new room database to store your messages. It's table should look like this:
id
message
sendingUser
receivingUser
0
Hello how are you?
John
David
1
Thanks, im good.
David
John
2
good to hear that!
John
David
First create a new Message class. This class should look like this:
#Entity(tableName = "message_table")
data class Message(
#PrimaryKey(autoGenerate = true)
var id: Int,
#ColumnInfo(name= "message")
var message: String,
#ColumnInfo(name = "sendingUser")
var sendingUser: String,
#ColumnInfo(name = "receivingUser")
var receivingUser: String
)
Then create your MessageDatabase, like this:
#Database(entities = [Message::class], version = 1)
abstract class MessageDatabase: RoomDatabase() {
abstract fun messageDao(): MessageDao
}
Next create your MessageDao
#Dao
interface MessageDao {
#Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun insert(message: Message)
#Query("SELECT ALL * FROM message_table WHERE sendingUser= :sendingUser")
suspend fun getMessageListFromSender(sendingUser: String): MutableList<Message>
#Query("SELECT ALL * FROM message_table")
suspend fun getMessageList(): MutableList<Message>
#Delete
suspend fun delete(message: Message)
#Update
suspend fun update(message: Message)
}
At last you can initialize your room database like this:
private val roomDb = Room.databaseBuilder(
getApplication(),
MessageDatabase::class.java, "message_database"
).build()
private val messageDao = roomDb.messageDao()
Use messageDao, to make operations with the database, this example shows you how to get message list from a certain sender:
suspend fun getMessageListFromSender(sendingUser: String): MutableList<Message> {
var list : MutableList<Message>
with (messageDao) {
list = this.getMessageListFromSender(sendingUser)
}
return list
}
viewModelScope.launch {
getMessageListFromSender("John")
}

In App Purchases - How to handle the second click?

i just want to implement in-app-purchasement into my app. It is a card game with different rulesets. So now want to implement 2 new rulesets which should work as my products and with in-app-purchasement.
I have this:
`go = (Button)findViewById(R.id.go);
go.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ArrayList skuList = new ArrayList();
skuList.add(inappid);
Bundle querySkus = new Bundle();
querySkus.putStringArrayList("ITEM_ID_LIST", skuList);
Bundle skuDetails;
try {
skuDetails = mservice.getSkuDetails(3, getPackageName(),
"inapp", querySkus);
int response = skuDetails.getInt("RESPONSE_CODE");
if (response == 0) {
ArrayList<String> responseList =
skuDetails.getStringArrayList("DETAILS_LIST");
for (String thisResponse : responseList) {
JSONObject object = new JSONObject(thisResponse);
String sku = object.getString("productId");
String price = object.getString("price");
if (sku.equals(inappid)) {
System.out.println("price " + price);
Bundle buyIntentBundle =
mservice.getBuyIntent(3, getPackageName(), sku,
"inapp",
"blablabla");
PendingIntent pendingIntent =
buyIntentBundle.getParcelable("BUY_INTENT");
startIntentSenderForResult(
pendingIntent.getIntentSender(), 1001,
new Intent(), Integer.valueOf(0),
Integer.valueOf(0), Integer.valueOf(0));
}
}
}
} catch (RemoteException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
} catch (IntentSender.SendIntentException e ) {
e.printStackTrace();
}
}
});`
First click on my ruleset works fine. The second click triggers the app to break down with the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.IntentSender android.app.PendingIntent.getIntentSender()' on a null object reference
Do you have some good in-app tutorials or a tipp for me?
Thanks in advance
JD

Here is my BaseClass that i use everywhere i need. Just extend your activity by this BaseInAppPurchaseActivity
Bonus in this class.
You can get what items are available for purchase so user can not get future exception if item is not available like
checkAvailablePurchases(skuList, new OnResultInApp() {
#Override
public void onResult(ArrayList<AvailablePurchase> availablePurchaseArrayList) {
.. logic for showing view with available purchaseItem
}
});
For purchasing an item
purchaseItem(googleInAppId, new OnResultPurchase() {
#Override
public void onSuccess(PurchaseResponseBean purchaseResponseBean, String inAppPurchaseData) {
// your stuff
}
#Override
public void onError() {
showToast(R.string.something_went_wrong);
}
});
Isn't this look pretty clean and nice.

There is some trouble with the getImageUrl() method in MainActivity.class.
Help me out guys!!

Replace your getImageUrl() like this
private String getImageUrl() {
String imurl;
Call<ImageModel> call = apiService.getImageDetails("js","0","1","en-US");
call.enqueue(new Callback<ImageModel>() {
#Override
public void onResponse(Response<ImageModel> response, Retrofit retrofit) {
try {
Toast.makeText(MainActivity.this, "inside onresponse()", Toast.LENGTH_SHORT).show();
imurl=response.body().getImages().get(0).getUrl().toString();
//Here variable "url" is showing the data obtained through json
// but not reflecting changes back in "oncreate" method when used with variable "Download_uri"
Toast.makeText(MainActivity.this, url, Toast.LENGTH_SHORT).show();
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public void onFailure(Throwable t) {
Toast.makeText(MainActivity.this, "Cannot download the image", Toast.LENGTH_SHORT).show();
}
});
return imurl;
}
and in oncreate change,
Download_Uri = Uri.parse(url);
by this
Download_Uri = Uri.parse(getImageUrl());

Util Class in Java

I want to know about the util Class used in Java. I am currently working on one Application in Android where I need to used a class from one file to another different file. I was told to import it like import com.android.utli.(ClassName) here the "com.android.util" is a package name.
Can I use that class in my another file simply by importing the package along with the class name?

Yes. After you import the class at the top of your java file like:
import android.util.Log;
You can then use it in your code.
Log.debug("MyActivity", "Thing I want to log");

The package is really a part of the "fully qualified class name". You can actually use that fully qualified name everywhere you use the class name, e.g.
com.android.util.UtilClass myUtil = new com.android.util.UtilClass();
But that's rather inconvenient. Therefore, classes in the same package (and in the package java.lang) can be used shorthand (i.e. only the class name) without imports. Classes from other packages have to be imported before they can be used that way.
It's just a way to organize the code and prevent problems when different programmers write classes with the same name - as long as they are in different packages, the collision can always be resolved by using the fully qualified class name.
