My application was working normally but then when I added the splash screen an error has been appeared and I don't know what to do or how t solve it
the error is
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setOnClickListener(android.view.View$OnClickListener)' on a null object reference
my MainActivity
public class MainActivity extends AppCompatActivity {
private final int SPLASH_DISPLAY_LENGTH = 4000;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent splashIntent = new Intent(MainActivity.this , SplashActivity.class);
MainActivity.this.startActivity(splashIntent);
MainActivity.this.finish();
}
},SPLASH_DISPLAY_LENGTH);
// Find the View that shows the numbers category
TextView numbers = (TextView) findViewById(R.id.numbers);
// Set a click listener on that View
numbers.setOnClickListener(new OnClickListener() {
// The code in this method will be executed when the numbers category is clicked on.
@Override
public void onClick(View view) {
// Create a new intent to open the {@link NumbersActivity}
Intent numbersIntent = new Intent(MainActivity.this, NumbersActivity.class);
// Start the new activity
startActivity(numbersIntent);
}
});
and the activity_splash
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

<TextView

android:layout_marginBottom="30dp"
android:layout_marginLeft="40dp"

SplashActivity
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
}
}
anything to solve it?
