I'm new to the Android SDK as well as Android Studio, but I'm familiar with programming. I have two activities that should be linked together, but for whatever reason my app crashes on launch due to an error in one of my XML files in regards to a TextView object I created. I have no idea what's going on from there. Any help is appreciated!
I'm 90% sure this file is the culprit. I can upload more code on request if you think that it is necessary. Below is the error.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
public class LoginActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
}
public void logIn(View view){
Intent intent = new Intent(this, HomePageActivity.class);
EditText editText = (EditText) findViewById(R.id.login_username);
String username = editText.getText().toString();
intent.putExtra("username", username);
startActivity(intent);
}
}
Here's the activity I'm trying to load:
package com.txfbla.benjamin.fblattire;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
public class HomePageActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home_page);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
}
Here's the error I'm getting:

You can't set textColor from a string resource. You can either hard code the value like #FFFFFF or save the value in colors.xml file
colors.xml
<color name="white">#FFFFFF</color>
Change
<TextView android:id="@+id/login_usernameHeading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/username"
android:textSize="18sp"
android:textColor="@string/login_blue "/>
to
<TextView android:id="@+id/login_usernameHeading"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/username"
android:textSize="18sp"
android:textColor="@color/white" />
Similarly change the second TextView textColor to color resource.
