Can not resolve method ‘findViewById(int)’

getActivity().findViewById() works. However, this isn’t a good practice because the fragment may be reused in another activity.

The recommended way for this is to define an interface.

The interface should contain methods by which the fragment needs to communicate with its parent activity. public interface MyInterfcae { void showTextView(); }

Then your activity implements that Interface. public class MyActivity extends Activity implements MyInterfcae { @Override public void showTextView(){ findViewById(R.id.textview).setVisibility(View.VISIBLE); } }

In that fragment grab a reference to the interface. MyInterface mif = (MyInterface) getActivity();

Call a method. mif.showTextView();

This way, the fragment and the activity are fully decoupled and every activity which implements that fragment, is able to attach that fragment to itself.

Cannot resolve method ‘findViewByID(int)’ in Android Studio

I only just started coding for androud, but I’ve been getting the error: “Cannot resolve method ‘findViewByID(int)’” in android studio

I can’t seem to find out what is wrong, have tried setting contentView, implementing OnClickListenener, but none of these fixed anything.

full code below, the MainActivity Method is where it all happens:

package aprivate.contract.jdeko.dww_registration; import android.net.Uri; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.view.View.OnClickListener; import com.google.android.gms.appindexing.Action; import com.google.android.gms.appindexing.AppIndex; import com.google.android.gms.common.api.GoogleApiClient; public class MainActivity extends AppCompatActivity{ private GoogleApiClient client; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Button clickButton = (Button) findViewByID(R.id.Btn); clickButton.setOnClickListener( new OnClickListener() { @Override public void onClick(View v) { //todo } }); } @Override public void onStart() { super.onStart(); // ATTENTION: This was auto-generated to implement the App Indexing API. // See https://g.co/AppIndexing/AndroidStudio for more information. client.connect(); Action viewAction = Action.newAction( Action.TYPE_VIEW, // TODO: choose an action type. “Main Page”, // TODO: Define a title for the content shown. // TODO: If you have web page content that matches this app activity’s content, // make sure this auto-generated web page URL is correct. // Otherwise, set the URL to null. Uri.parse(“http://host/path”), // TODO: Make sure this auto-generated app URL is correct. Uri.parse(“android-app://aprivate.contract.jdeko.dww_registration/http/host/path”) ); AppIndex.AppIndexApi.start(client, viewAction); } @Override public void onStop() { super.onStop(); // ATTENTION: This was auto-generated to implement the App Indexing API. // See https://g.co/AppIndexing/AndroidStudio for more information. Action viewAction = Action.newAction( Action.TYPE_VIEW, // TODO: choose an action type. “Main Page”, // TODO: Define a title for the content shown. // TODO: If you have web page content that matches this app activity’s content, // make sure this auto-generated web page URL is correct. // Otherwise, set the URL to null. Uri.parse(“http://host/path”), // TODO: Make sure this auto-generated app URL is correct. Uri.parse(“android-app://aprivate.contract.jdeko.dww_registration/http/host/path”) ); AppIndex.AppIndexApi.end(client, viewAction); client.disconnect(); } }

Answer

It’s just a typo that you have made. You should use “Id” instead of “ID”.

So your

Button clickButton = (Button) findViewByID(R.id.Btn);

Becomes

Activity.FindViewById Method (Android.App)

FindViewById(Int32)

Finds a view that was identified by the android:id XML attribute that was processed in #onCreate .

[] abstract member FindViewById : int -> Android.Views.View override this.FindViewById : int -> Android.Views.View

Parameters

id Int32 the ID to search for

Returns

a view with given ID if found, or null otherwise

Attributes RegisterAttribute

findViewById in Fragment

I am trying to create an ImageView in a Fragment which will refer to the ImageView element which I have created in the XML for the Fragment. However, the findViewById method only works if I extend an Activity class. Is there anyway of which I can use it in Fragment as well?

public class TestClass extends Fragment { public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { ImageView imageView = (ImageView)findViewById(R.id.my_image); return inflater.inflate(R.layout.testclassfragment, container, false); } }

How does findViewById work?

in the XML file when we add an element and set the properties to it we only set the values for these properties, now for each element, there is a class that draws it at the screen, this class has attributes with the same names of the properties in the XML file now using algorithms of read-write from files these values from the XML file are transmitted to the java file (class) of the element, and then the class draws that element on the screen.

Before the class of the element draws it, there is a superclass of all elements, the parent for all of them it is called View (every element in the activity is called view) this class has the basic properties of all elements and this class is the one which the properties from the XML file will be transmitted to it.

Method findViewById() returns an object of View type, this object holds the properties values then we need to cast it to the specific element, for example, TextView which is a class to draw the text view this class and all elements’ classes are subclasses of View class so what we do is downcasting, that when this method returns the object of View type we downcast it to the element class

How it finds the properties? it finds the properties of the element using the id if the tag in the XML file first it searches in the XML file for the tag that holds the element’s name and then it looks at the id if it is the id which it wants then it takes it otherwise it searches for another tag (with the same element name).

We give it the id by this approach. there is a class is called R (resources), this class has nested classes (id, string, colors) these classes have attributes from the same type and hold specific values, for instance, the id class it has attributes that stores each id of each element in the XML file, so when we want to give the method findViewById() the id we go to this class and tell it to enter id class and choose the id of the element we want.

ِِAnd the process goes that it enters to the XML file and look for the element that has this id and it takes the properties and passes them to the class view object and when it returns the object we downcast it to the element’s class that we want to draw it and deal with it.

Android what is the need to cast return of findViewById()?

To get a View from XML in Android findViewById() is used let’s say a ListView.

Due to the fact that findViewById() returns a parent View object rather than ListView object we need to cast the return of findViewById()

ListView listView = (ListView) findViewById(R.id.listView);

Output of findViewById() without casting:

System.out.println(findViewById(R.id.mainListView).getClass()); // class android.widget.ListView System.out.println(findViewById(R.id.mainListView).getClass().getSimpleName()); // ListView System.out.println((findViewById(R.id.mainListView) instanceof ListView)); // true

Can not resolve method ‘findViewById(int)’

You need to do this in onCreateView:

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.secondefragment, container, false);

mWebView = (WebView) view.findViewById(R.id.activity_main_webview);

progressBar = (ProgressBar) view.findViewById(R.id.progressBar1);

WebSettings webSettings = mWebView.getSettings();

webSettings.setJavaScriptEnabled(true);

mWebView.loadUrl(“http://www.google.com”);

return view;

}

Fragment doesn’t provide thefindViewById() method. This is provided in Activity or View. When implementing a Fragment you don’t inflate your views in onCreate() (like you normally do in an Activity.) Instead, you do it in onCreateView() and you need to use the inflated root View to find the ID within the layout you inflated.

Cannot resolve findViewById in fragment

Is there anyway of which I can use findViewById in Fragment ?

i am trying to get id from fragment xml so here is the code the error is ” Cannot resolve the method findViewById ”

Answer

Firstly, you are calling findViewById() after the return statement so they wont be executed at all. Next, you need to call findViewById() on the context of a view as in view.findViewById(int); so rewrite the code as :

View v = inflater.inflate(R.layout.activity_slide__teacher_add,container,false); teacher_id_number = v.findViewById(R.id.teacher_id_number); //Note this line //other tasks you need to do return v;
