主活动.java

    package com.example.ghaas.androideatit;

import android.graphics.Typeface;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

    Button btnSignIn,btnSignUp;
    TextView txtSlogan;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnSignIn = (Button)findViewById(R.id.btnSignIn);
        btnSignUp = (Button)findViewById(R.id.btnSignUp);

        txtSlogan = (TextView)findViewById(R.id.txtSlogan);
        Typeface face = Typeface.createFromAsset(getAssets(),"fonts/Nabila.ttf");
        txtSlogan.setTypeface(face);

        btnSignIn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });

        btnSignUp.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

            }
        });

    }
}

我该如何修复此问题？

问候，

测试替换这个：

btnSignIn = (Button)findViewById(R.id.btnSignIn);
btnSignUp = (Button)findViewById(R.id.btnSignUp);

为了：

btnSignIn = (FButton)findById(R.id.btnSignIn);
btnSignUp = (FButton)findById(R.id.btnSignUp);
