Fehler: Leider App gestoppt

-2

Ich lerne Android und folgte dem Tutorial in Wingnity. Ich benutze Android Studio 2.1.3.Fehler: Leider App gestoppt

Ich habe 2 Java-Klassen (MainActivity und SimpleFragmentActivity) und 3 Layout (activity_main, activity_simple_fragment und Fragment einfach (leer)).

Ich bin nicht sicher, was mit meinem Code falsch ist. Versucht, nach der Lösung zu suchen, aber der Code scheint korrekt zu sein.

MainActivity

package com.example.ramosva.sunshine; 

import android.app.Fragment; 
import android.content.Intent; 
import android.support.v4.app.FragmentActivity; 
import android.support.v7.app.ActionBar; 
import android.support.v7.app.ActionBarActivity; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.view.View; 
import android.view.ViewGroup; 
import android.support.v4.app.DialogFragment; 
import android.widget.Adapter; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

import java.lang.reflect.Array; 
import java.util.ArrayList; 
import java.util.List; 
import java.lang.Object; 
import java.util.Arrays; 


public class MainActivity extends AppCompatActivity { 

    ListView listView; 

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



    } 

    public void simples(View v){ 

       Intent intent = new Intent(getApplicationContext(), SimpleFragmentActivity.class); 
       startActivity(intent); 
//  startService(intent); 

    } 

}

SimpleFragmentActivity

package com.example.ramosva.sunshine; 


import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v7.app.AppCompatActivity; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.Button; 
import android.widget.Toast; 


/** 
* A simple {@link Fragment} subclass. 
*/ 
public class SimpleFragmentActivity extends AppCompatActivity { 


    public SimpleFragmentActivity() { 
     // Required empty public constructor 
    } 

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

     if(savedInstanceState == null){ 
      getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit(); 
     } 
    } 

    public static class PlaceholderFragment extends Fragment{ 

     public PlaceholderFragment(){ 

     } 

     @Override 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, 
           Bundle savedInstanceState) { 
      // Inflate the layout for this fragment 
      View rootview = inflater.inflate(R.layout.activity_simple_fragment, container, false); 

      Button btnClickMeGym = (Button)rootview.findViewById(R.id.btnSimpleFragGym); 
      btnClickMeGym.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View v) { 

        Toast.makeText(getActivity(), "You clicked me Gym", Toast.LENGTH_SHORT).show(); 
       } 
      }); 
      return rootview; 
     } 

    } 

}

Kann hier den Fehler hinweisen jemand bitte. Ich folgte nur dem Code, der in Wingnity Tutorial 1: Erstellen von Fragmenten verwendet wurde.

Fügen Sie den Fehler (logcat) – Zoe

Welche Aktivitäten lade Sie zuerst? Wenn 'MainActivity', wie nennt man' Simple' darin? Was ist der Auslöser für den Absturz (sofort, nach einem Klick usw.)? Schließlich teilen Sie IMMER Fehlerprotokolle, wenn Sie nach Fehlern fragen. – Shaishav

Die Fehlerprotokolle wurden hinzugefügt. Entschuldigung dafür. –

Ändern Sie diese Zeile

setContentView(R.layout.activity_simple_fragment);

setContentView(R.layout.fragment_simple);

Sie können nicht zwei gleiche Layout in Fragment und Wurzel overrite. Es sollte anders seine

Versucht, es zu ändern, aber der Fehler tritt immer noch auf. –

Uncheck Instant-Lauf und versuchen \t deaktivieren Instant-Run: Einstellungen → Bauen, Durchführung, Bereitstellung → Instant-Run und deaktivieren aktivieren Instant-Run – Halumz

es versucht. Fehler kommt immer noch :( –

Sie haben versucht, durch ein Fragment zu einem Layout hinzufügen getSupportFragmentManager().beginTransaction().add(R.id.container, new PlaceholderFragment()).commit(); in Ihrem SimpleFragmentActivity nennen, aber es gibt kein Layout von id ist container in Ihrem activity_simple_fragment.xml. Sie müssen also ein Layout hinzufügen und seine ID auf container in activity_simple_fragment.xml setzen.

gerade versucht, die android: id = "@ + ID/Container" in activity_main.xml zu activity_simple_fragment.xml und Fehler immer noch kommt. –

Es heißt java.lang.IllegalStateException: Could not find method simples(View) in a parent or ancestor Context for android:onClick attribute defined on view class Vermeiden Sie onClick in XML verwenden.

public class MainActivity extends AppCompatActivity { 

ListView listView; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Button button = (Button) findViewById(R.id.btnSimpleFragmentMain); 
    button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      startActivity(new Intent(getApplicationContext(), SimpleFragmentActivity.class);); 
     } 
    }); 
    } 
}

Hier

<Button 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="Simple Fragment" 
    android:id="@+id/btnSimpleFragmentMain" 
    android:layout_gravity="center_horizontal"/>
