我是Android SDK和Android Studio的新手，但我对编程很熟悉。我有两个活动应该链接在一起，但是无论出于什么原因，由于我的一个XML文件中与我创建的TextView对象有关的错误，我的应用程序在启动时崩溃。我不知道那是怎么回事。任何帮助表示赞赏！
我90％确信此文件是罪魁祸首。如果您认为有必要，我可以根据要求上传更多代码。下面是错误。
package com.txfbla.benjamin.fblattire;
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);
}
}
这是我要加载的活动：
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);
}
}
这是我得到的错误：

您无法通过字符串资源设置textColor。您可以硬编码#FFFFFF之类的值，也可以将该值保存在colors.xml文件中
colors.xml
#FFFFFF
更改
至
同样，将第二个TextView textColor更改为颜色资源。
