Как исправить «E / AndroidRuntime: FATAL EXCEPTION: main» в Android Studio?

Question

Он уже скомпилирован и APK установлен. Но когда я пытаюсь открыть его в своем телефоне Android, он продолжает принудительно закрываться.

Я пробовал на нескольких устройствах, считая, что это версия для телефона Android, но проблема не в этом.

MainActivity.java

package com.example.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 v) {

            }
        });

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

            }
        });
    }
}

Я надеюсь, что это больше не заставит закрыться. В настоящее время я следую видеоурок в https://www.youtube.com/watch?v=Ad41Bh704ms&t=6s

Answer 1

Внутри вашего макета вы используете

<info.hoang8f.widget.FButton

но в своей деятельности вы используете Button

также замените app пространство имен на fbutton

    <info.hoang8f.widget.FButton
        xmlns:fbutton="http://schemas.android.com/apk/res-auto"
        android:id="@+id/btnSignUp"
        android:text="Sign Up"
        android:textColor="@android:color/white"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        fbutton:buttonColor="@color/btnSignUp"
        fbutton:shadowColor="@android:color/black"
        fbutton:shadowEnabled="true"
        fbutton:shadowHeight="5dp"
        fbutton:cornerRadius="4dp"
        />

      <info.hoang8f.widget.FButton
        xmlns:fbutton="http://schemas.android.com/apk/res-auto"
        android:id="@+id/btnSignIn"
        android:text="Sign In"
        android:textColor="@android:color/white"
        android:layout_weight="1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_margin="8dp"
        fbutton:buttonColor="@color/btnSignActive"
        fbutton:shadowColor="@android:color/black"
        fbutton:shadowEnabled="true"
        fbutton:shadowHeight="5dp"
        fbutton:cornerRadius="4dp"
        />

MainActivity

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