Java &引用；不幸的是，MyApp已经停止了；当我按下按钮时

我用在github上找到的代码做了一个问答游戏，因为我是个新手，我想学习编程。 所以，当我按下开始按钮时，游戏崩溃了。我在没有其他课程的情况下尝试了它，但它仍然崩溃。还有我的MainActivity类、mainActivityXML和AndroidManifest

MainActivity.java

package com.proje.bilgiyarismasi.bilgiyarismasi;

import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageButton;


public class MainActivity extends AppCompatActivity {
ImageButton baslat,ayarlar;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    baslat = findViewById(R.id.baslatButonu);
    ayarlar = findViewById(R.id.ayarlarButonu);
    baslat.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(MainActivity.this, SoruAlani.class);
            startActivity(intent);
            finish();

        }

    });
    ayarlar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(MainActivity.this,Ayarlar.class);
            startActivity(intent);
            finish();
        }
    });

}
}

谢谢您的帮助。

您没有正确铸造图像按钮

在

onCreate（）中使用此选项

并在清单中声明此活动

<activity android:name=".Ayarlar">

也添加此字体文件
Bariol_Regular.otf

请检查此链接
只添加日志中的例外部分从
android:layout\u alignBottom=“@+id/baslatButonu”
在playButtonlearn调试中，youtube上有很多视频。学习发布崩溃日志，查找无法调试的bug。阅读此日志，了解+id，无需在新的android studio中进行id转换。我认为活动名称是MAinActivity，不是吗？是的，你是对的，不能说@Kangaetemo在3.0中使用sdk 26:）对不起，我忘了添加我使用的是2.3.3。感谢您的回答，但游戏仍然崩溃，我在logcatjava.lang.RuntimeException上看不到任何新内容：无法启动活动请在清单中声明此活动，如果您没有添加它，请在java.lang.RuntimeException:Font asset not found fonts/Bariol_Regular.otf
    baslat = (ImageButton)findViewById(R.id.baslatButonu);
    ayarlar =(ImageButton) findViewById(R.id.ayarlarButonu);

<activity android:name=".Ayarlar">
