how to set visibility options of android.widget.textview

had FC issues with this ``` private TextView msg, NameOut, DateOut; msg = (TextView) findViewById(R.id.txtviewOut) ; ``` down the line... (problem lies here) ``` msg.setVisibility(View.INVISIBLE);//set visibility to false on create ``` how do I set the visibility of this TextView (msg) to false when the app starts? UPDATE AFTER #1 Answer EDIT okay here is all the code: fragment_main.xml ``` <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity$PlaceholderFragment"> <EditText android:id="@+id/textenter" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_below="@+id/lbledt1" android:layout_alignParentLeft="true" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Enter Name" android:id="@+id/lbledt1" android:layout_marginTop="26dp" android:layout_centerHorizontal="true" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Enter your date of birth (e.g. xx July 19xx)" android:id="@+id/textView" android:layout_below="@+id/textenter" android:layout_centerHorizontal="true" android:layout_marginTop="57dp" /> <EditText android:id="@+id/editText" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_below="@+id/textView" android:layout_alignParentLeft="true" /> <Button android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Press this button" android:id="@+id/button" android:layout_centerVertical="true" android:layout_centerHorizontal="true" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceLarge" android:text="You have been awesome since" android:id="@+id/txtviewOut" android:layout_marginTop="86dp" android:textIsSelectable="false" android:layout_below="@+id/button" android:layout_centerHorizontal="true" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceLarge" android:id="@+id/txtoutName" android:textIsSelectable="false" android:layout_alignBottom="@+id/txtviewOut" android:layout_centerHorizontal="true" android:layout_marginBottom="41dp" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textAppearance="?android:attr/textAppearanceLarge" android:id="@+id/txtOutDate" android:layout_marginTop="28dp" android:textIsSelectable="false" android:layout_below="@+id/txtviewOut" android:layout_centerHorizontal="true" /> ``` ``` MainActivity.java: package com.example.helloandroidstudio; import android.support.v7.app.ActionBarActivity; import android.support.v7.app.ActionBar; import android.support.v4.app.Fragment; 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.os.Build; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; public class MainActivity extends ActionBarActivity { private Button btnClick; private EditText Name, Date; private TextView msg, NameOut, DateOut; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); btnClick = (Button) findViewById(R.id.button) ; Name = (EditText) findViewById(R.id.textenter) ; Date = (EditText) findViewById(R.id.editText) ; msg = (TextView) findViewById(R.id.txtviewOut) ; NameOut = (TextView) findViewById(R.id.txtoutName) ; DateOut = (TextView) findViewById(R.id.txtOutDate) ; // msg.setVisibility(View.GONE);//set visibility to false on create if (savedInstanceState == null) { getSupportFragmentManager().beginTransaction() .add(R.id.container, new PlaceholderFragment()) .commit(); } } public void onClick(View v) { if (v == btnClick) { if (Name.equals("") == false && Date.equals("") == false) { NameOut = Name; DateOut = Date; msg.setVisibility(View.VISIBLE); } else { msg.setText("Please complete both fields"); msg.setVisibility(View.VISIBLE); } } } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle action bar item clicks here.
