App stoppt beim Start einer neuen Aktivität

Question

Ich habe versucht, eine neue Aktivität in meiner App zu starten und, obwohl es für einen Moment, sofort nach dem Öffnen des neuen Bildschirms, die App stoppt. Ich habe dem Manifest bereits die neue Aktivität hinzugefügt. Dies ist die Methode, die ich auf die neue Tätigkeit zu verwenden Anruf, whuich perfekt funktioniert, wenn es nur den Toast im clicklistener hatte:

public void Bs() 
    { 
     View.OnClickListener listSet = new View.OnClickListener() 
     { 
      @Override 
      public void onClick(View view) 
      { 
       Toast.makeText(getApplicationContext(), "settings", Toast.LENGTH_LONG).show(); 
       Intent intent= new Intent(MainActivity.this, Set.class); 
       startActivity(intent); 
      } 
     }; 
     b= (ImageButton) findViewById(R.id.imageButton7); 
     b.setOnClickListener(listSet); 
    } 

Dies ist die Klasse, die aufgerufen wird:

public class Set extends Activity 
{ 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.settings); 
    } 
} 

und das ist die Layout-Klasse Einstellung, die nur über ein textview (ich habe versucht, mehrere Layouts und nne von ihnen arbeiten, so dass ich denke, das ist nicht das Problem, aber ich hinzufügen, es trotzdem, falls es hilft):

?xml version="1.0" encoding="utf-8"?> 
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <TextView 
     android:id="@+id/textView" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginBottom="8dp" 
     android:layout_marginLeft="8dp" 
     android:layout_marginRight="8dp" 
     android:layout_marginTop="0dp" 
     android:text="@string/toolbar" 
     app:layout_constraintBottom_toBottomOf="parent" 
     app:layout_constraintLeft_toLeftOf="parent" 
     app:layout_constraintRight_toRightOf="parent" 
     app:layout_constraintTop_toTopOf="parent" /> 
</android.support.constraint.ConstraintLayout> 

Dies sind die Fehler, die ich in der logcat haben:

Bin ich etwas falsch zu machen, wenn die neue Tätigkeit nennen? Oder ist es die Klasse, die ich anrufe, ist die eine nicht in Ordnung?

EDIT Das ist mein Manifest:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.xx.yy"> 
    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> 
    <application 
     android:debuggable="false" 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:roundIcon="@mipmap/ic_launcher_round" 
     android:supportsRtl="true" 
     android:theme="@style/AppTheme"> 
     <activity android:name="com.xx.yy.MainActivity" 
       android:configChanges= "orientation|screenSize" 
       android:label="@string/app_name"> 
       <intent-filter> 
        <action android:name="android.intent.action.MAIN" /> 
        <category android:name="android.intent.category.LAUNCHER" /> 
       </intent-filter> 
     </activity> 
     <activity 
      android:name="com.xx.yy.Set" 
      android:screenOrientation="portrait"> 
     </activity> 
    </application> 
</manifest> 

Answer 1

Ich habe einige weitere Versuche unternommen worden, zu tun, und ich denke, das Problem war ich auf der ersten Aktivität war größer anzeigen, aber nicht auf dem zweiten . Daher hat das Hinzufügen dieser beiden Zeilen zur Set-Klasse das Problem gelöst:

Answer 2

Können Sie Ihre Datei MANIFEST teilen hier

Ich versuchte, die ähnliche Art von Code, den Sie geschrieben wurden, Überprüfen Sie den Arbeitscode unten.

MainActivity.java

package com.service.rajeshm.activitytest; 

import android.content.Intent; 
import android.media.Image; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
import android.widget.ImageButton; 
import android.widget.Toast; 

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     View.OnClickListener listSet = new View.OnClickListener() 
     { 
      @Override 
      public void onClick(View view) 
      { 
       Toast.makeText(getApplicationContext(), "settings", Toast.LENGTH_LONG).show(); 
       Intent intent= new Intent(MainActivity.this, Set.class); 
       startActivity(intent); 
      } 
     }; 
     ImageButton b= (ImageButton) findViewById(R.id.imageButton1); 
     b.setOnClickListener(listSet); 
    } 
}
