LinearLayout is null inside button's onClick

I'm trying to hide a linearlayout on a button click and display another linearlayout which is in the same layout file. But the linearlayouts are null inside the onclick of the button.
The displayLayout and editLayout are null.
displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
displayLayout.setVisibility(View.GONE); //error occurs here
editLayout.setVisibility(View.VISIBLE);
}
});
}

Just fix your view ID in your code
displayLayout = (LinearLayout) findViewById(R.id.displayLayout);
editLayout = (LinearLayout) findViewById(R.id.editLayout);
edit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
displayLayout.setVisibility(View.GONE);
editLayout.setVisibility(View.VISIBLE);
}
});
}

error code displayLayout = (LinearLayout) findViewById(R.id.linearLayout);
right code displayLayout = (LinearLayout) findViewById(R.id.displayLayout);
you set a not exist id.

you need to use a scrollview , just insert your XML contents inside this before the and it should work:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView1"

android:layout_height="match_parent" >
</ScrollView>

final EditText s = (EditText) inflatedView.findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);

you can also simple use this:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText s = (EditText) findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);
}

Do this way
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText s = (EditText) findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);
// or
View inflatedView = getLayoutInflater().inflate(R.layout.activity_main, null);
final EditText s = (EditText) inflatedView.findViewById(R.id.textView2);
userid = "99999";
s.setText(userid);
setContentView(inflatedView);
}
