I have an Fragment...class in which I am inflating an xml file. This Fragment is being called in Mainactivity...but when executed this error appears

java.lang.Runtimeexception: Unable to start Activity Componentinfo{com.br.comunicacao/com.br.comunicacao.Mainactivity}: android.view.Inflateexception: Binary XML file line #30: Binary XML file line #30: Error inflating class Fragment at android.app.Activitythread.performLaunchActivity(Activitythread.java:2434) at android.app.Activitythread.handleLaunchActivity(Activitythread.java:2494) at android.app.Activitythread.access$900(Activitythread.java:153) at android.app.Activitythread$H.handleMessage(Activitythread.java:1347) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:148) at android.app.Activitythread.main(Activitythread.java:5451) at java.lang.reflect.Method.invoke(Native Method) at com.android.Internal.os.Zygoteinit$Methodandargscaller.run(Zygoteinit.java:726) at com.android.Internal.os.Zygoteinit.main(Zygoteinit.java:616) Caused by: android.view.Inflateexception: Binary XML file line #30: Binary XML file line #30: Error inflating class Fragment at android.view.Layoutinflater.inflate(Layoutinflater.java:539) at android.view.Layoutinflater.inflate(Layoutinflater.java:423) at android.view.Layoutinflater.inflate(Layoutinflater.java:374) at com.android.Internal.policy.Phonewindow.setContentView(Phonewindow.java:393) at android.app.Activity.setContentView(Activity.java:2215) at com.br.comunicacao.MainActivity.onCreate(Mainactivity.java:27) at android.app.Activity.performCreate(Activity.java:6323) at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1108) at android.app.Activitythread.performLaunchActivity(Activitythread.java:2387) at android.app.Activitythread.handleLaunchActivity(Activitythread.java:2494)  at android.app.Activitythread.access$900(Activitythread.java:153)  at android.app.Activitythread$H.handleMessage(Activitythread.java:1347)  at android.os.Handler.dispatchMessage(Handler.java:102)  at android.os.Looper.loop(Looper.java:148)  at android.app.Activitythread.main(Activitythread.java:5451)  at java.lang.reflect.Method.invoke(Native Method)  at com.android.Internal.os.Zygoteinit$Methodandargscaller.run(Zygoteinit.java:726)  at com.android.Internal.os.Zygoteinit.main(Zygoteinit.java:616)

This is my Fragment class code:

    public class Fragment1 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup conteiner, Bundle saveInstanceState){
        View view = inflater.inflate(R.layout.layout_frag_1, conteiner);

        return null;
    }


}

And this is Mainactivity’s:

public class MainActivity extends FragmentActivity {
FragmentManager fm = getSupportFragmentManager();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    String[] lista = new String[]{"ALMOÇO","BEBIDAS","COMO ESTOU ME SENTINDO","FAMILIA"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,lista);
    ListView lv = (ListView) findViewById(R.id.listView2);
    lv.setAdapter(adapter);
    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> lv, View view, int position, long id) {
            if (position == 1){
                Fragment1 fragment1 = (Fragment1) fm.findFragmentById(R.id.fragment1);
            }
        }
    });

}

You are returning null in view creation.

Try:

public class Fragment1 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup conteiner, Bundle saveInstanceState){
    return inflater.inflate(R.layout.layout_frag_1, conteiner, false);
}

  • I already tried this, but the same error occurs.

  • Tried with false, as third parameter of the inflate method?

  • I just saw here the null return when I returned the view worked. Thank you!

1st option:

Check the layout_frag_1.xml, if the parent tag has Fragment id, example:

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:id="@+id/fragment1"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</LinearLayout>

second option:

Check the Imports, should be with Supports, given that you are using the getSupportFragmentManager(), examples:

import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.Fragment;

third option:

From the top menu of your Androidstudio, click Build and then in Clean Project
