Accessing TextView from other class in android

Accessing TextView from other class in android - android

Hello i am new to android.i was creating a simple google cloud appengine app with endpoint.i was using using this tutorial https://github.com/GoogleCloudPlatform/gradle-appengine-templates/tree/master/HelloEndpoints .but the thing is i want to show the result in a textview not in a toast.

Pass TextView as parameter to Constructor of EndpointsAsyncTask in which you want to show result as done below.
public class EndpointsAsyncTask extends AsyncTask<Pair<Context, String>, Void, String> {
private static MyApi myApiService = null;
private Context context;
private TextView textView
public EndpointsAsyncTask(Context context,TextView mtextView) {
// TODO Auto-generated constructor stub
this.context=context;
this.textView=mtextView;
}
#Override
protected String doInBackground(Pair<Context, String>... params) {
if (myApiService == null) { // Only do this once
/* MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null)
// options for running against local devappserver
// - 10.0.2.2 is localhost's IP address in Android emulator
// - turn off compression when running against local devappserver
.setRootUrl("http://10.0.2.2:8080/_ah/api/")
.setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
#Override
public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest) throws IOException {
abstractGoogleClientRequest.setDisableGZipContent(true);
}
});*/
MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(), new AndroidJsonFactory(), null)
.setRootUrl("https://leafy-display-112017.appspot.com/_ah/api/");
// end options for devappserver
myApiService = builder.build();
}
context = params[0].first;
String name = params[0].second;
try {
return myApiService.sayHi(name).execute().getData();
} catch (IOException e) {
return e.getMessage();
}
}
#Override
protected void onPostExecute(String result) {
Toast.makeText(context, result, Toast.LENGTH_LONG).show();
textView.setText(result);
}
}
call AsyncTask from you Activity or Fragment
new EndpointsAsyncTask(context,yourTextView).execute(yourParams);

In EndpointsAsyncTask.java replace
#Override
protected void onPostExecute(String result) {
Toast.makeText(context, result, Toast.LENGTH_LONG).show();
}
With
#Override
protected void onPostExecute(String result) {
GoogleAppEngActivity.getTextView().setText(result);
}

change to:new EndpointsAsyncTask(tv1) in GoogleAppEngActivity class
and add next code to EndpointsAsyncTask class
TextView view;
public EndpointsAsyncTask(TextView tv) {
view = tv;
}
and replace Toast.makeText(context, result, Toast.LENGTH_LONG).show();
to view.setText(result);

I'll suggest making EndpointsAsyncTask an inner class of your activity. Get a reference to textView in postExecute and update it there. Something like this

Ideally, the UI elements belonging to an activity should be changed in the activity itself, and no where else. Try following the presentation pattern.
A small example:
1. Create an interface - ActivityPresenter with methods signifying events with parameters as the input data required for the views to change. An example would be:
void onServerResponse(ServerResponse resp);
Make the activity implement this interface. That is, you define what UI changes to make in the activity when the server response arrives.
When you call a service / asynctask from the activity to do some task asynchronously for you, send the activity presenter reference. Call the presenter.onServerResponse(response) from your service / asynctask.

For this purpose you can use callback interface:
Create a public interface:
public interface AsyncTaskResponse {
void asyncTaskFinish(String output);
}
Now override the method of callback interface and define the action need to do i.e set the TextView value. After that pass it to async task class:
package com.ontech.googleappengine;
import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Pair;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class GoogleAppEngActivity extends AppCompatActivity {
Button btnAdd;
final TextView tv1;
//String val1,val2;
EditText edt1,edt2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_google_app_eng);
edt1=(EditText)findViewById(R.id.edt1);
edt2=(EditText)findViewById(R.id.edt2);
tv1=(TextView)findViewById(R.id.tv1);
btnAdd =(Button)findViewById(R.id.btnAdd);
btnAdd.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String temp = "";
temp = edt1.getText().toString();
temp += "+";
temp += edt2.getText().toString();
new EndpointsAsyncTask(new AsyncTaskResponse() {
#Override
public void asyncTaskFinish(String response) {
tv1.setText(response);
}
};).execute(new Pair<Context, String>(GoogleAppEngActivity.this, temp));
// tv1.setText( new EndpointsAsyncTask().);
}
});
// new EndpointsAsyncTask(new AsyncTaskResponse().execute(new Pair<Context, String>(this, "Manfred"));
}
public TextView getTextView(){
TextView txtView=(TextView)findViewById(R.id.tv1);
return txtView;
}
}
Now in async task class call the Callback interface method and pass response String to set edit text value:
package com.ontech.googleappengine;
//package com.ontech.googleappengine;
import android.content.Context;
import android.os.AsyncTask;
import android.text.Layout;
import android.util.Pair;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.Toast;
import com.google.api.client.extensions.android.http.AndroidHttp;
import com.google.api.client.extensions.android.json.AndroidJsonFactory;
import com.google.api.client.googleapis.services.AbstractGoogleClientRequest;
import com.google.api.client.googleapis.services.GoogleClientRequestInitializer;
import com.ontech.myapplication.backend.myApi.MyApi;
import java.io.IOException;
/**

*/
public class EndpointsAsyncTask extends AsyncTask<Pair<Context, String>, Void, String> {
private static MyApi myApiService = null;
private Context context;
private AsyncTaskResponse asyncCallback;
public EndpointsAsyncTask(AsyncTaskResponse asyncTaskResponse){
asyncCallback = asyncTaskResponse;
}
#Override
protected String doInBackground(Pair<Context, String>... params) {
if (myApiService == null) { // Only do this once
/* MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(),
new AndroidJsonFactory(), null)
// options for running against local devappserver
// - 10.0.2.2 is localhost's IP address in Android emulator
// - turn off compression when running against local devappserver
.setRootUrl("http://10.0.2.2:8080/_ah/api/")
.setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
#Override
public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest) throws IOException {
abstractGoogleClientRequest.setDisableGZipContent(true);
}
});*/
MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(), new AndroidJsonFactory(), null)
.setRootUrl("https://leafy-display-112017.appspot.com/_ah/api/");
// end options for devappserver
myApiService = builder.build();
}
context = params[0].first;
String name = params[0].second;
try {
return myApiService.sayHi(name).execute().getData();
} catch (IOException e) {
return e.getMessage();
}
}
#Override
protected void onPostExecute(String result) {
//Toast.makeText(context, result, Toast.LENGTH_LONG).show();
asyncCallback.asyncTaskFinish(result); // call the method of callback interface
}
}

I don't understand why 'onResponse()' is not triggered after successful response?

From the log I can see that the web service correctly returns the JSON to me. But for some reason it never enters the onResponse method.

I think you are not handling all case correctly like what if onFailure trigger for error.
I am not debugging you project so exact error i can tell you but i suggest you some links where you can find how to debug your code properly.

Not annotated parameter overrides #NonNull parameter
This is just a warning. You have
#Override
public View onCreateView(LayoutInflater inflater...
while the base class you're extending has nullity annotation on the inflater parameter.
public View onCreateView(#NonNull LayoutInflater inflater...
You can just alt-enter in Android Studio to get a quick fix menu that has the option to add the missing annotation there.
due to this error my code is not working.
Missing an annotation like that just causes a warning. The reason for "not working" is something else. Please start by updating your question and specifying what "not working" means to you here.

Try to change this line
View v = inflater.inflate(R.layout.fragment_files_listing, null);
to
View v = inflater.inflate(R.layout.fragment_files_listing, container, false);
This will inflate your layout with your fragment container.

You have to change this line
View v = inflater.inflate(R.layout.fragment_files_listing, null);
to
View v = inflater.inflate(R.layout.fragment_files_listing, container, false);
and then clean your project and invalidate cache restart you android studio.

Unable to get data from query results from Twitter API

I am new to Android. I can't get my ListView to populate.

Error await must not be called on the UI Thread in Android project

I am currently trying to read data from google drive, using a query then transferring the gson to a fragment so I can set the edit text values of said fragment to the gson being read in (Kudos if you followed that!)
Every time I move to open the fragment I am getting the following error message:

As stated in the Exception message, you shouldn't use await on the UI thread.
Setting a new thread to handle the data should fix it.
[EDIT 1]
The "onResult" function is called on the UI Thread as mentioned in https://developers.google.com/android/reference/com/google/android/gms/common/api/ResultCallback#public-method-summary
public abstract void onResult (R result)
Called when the Result is ready.
It is the responsibility of the callback to release any resources
associated with the result. Some result types may implement
Releasable, in which case release() should be used to free the
associated resources.
This method is called on the main thread, unless overridden by
setHandler(Handler).

Accessing TextView from other class in android - android

In EndpointsAsyncTask.java replace #Override protected void onPostExecute(String result) { Toast.makeText(context, result, Toast.LENGTH_LONG).show(); } With #Override protected void onPostExecute(String result) { GoogleAppEngActivity.getTextView().setText(result); }

change to:new EndpointsAsyncTask(tv1) in GoogleAppEngActivity class and add next code to EndpointsAsyncTask class TextView view; public EndpointsAsyncTask(TextView tv) { view = tv; } and replace Toast.makeText(context, result, Toast.LENGTH_LONG).show(); to view.setText(result);

I'll suggest making EndpointsAsyncTask an inner class of your activity. Get a reference to textView in postExecute and update it there. Something like this
