我用我在 github 上找到的代码做了一个问答游戏，因为我是新手，我想学习编程。
所以，当我按下开始按钮游戏崩溃。我在没有其他类(class)的情况下尝试过，但它仍然崩溃。有我的 MainActivity 类、MainActivity xml 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();
        }
    });

}
}

谢谢你的帮助。

Answer 1

您没有正确转换图像按钮。

在 onCreate() 中使用它

    baslat = (ImageButton)findViewById(R.id.baslatButonu);
    ayarlar =(ImageButton) findViewById(R.id.ayarlarButonu);

并在 list 中声明此 Activity

<activity android:name=".Ayarlar">

从日志猫

**java.lang.RuntimeException: Font asset not found fonts/Bariol_Regular.otf**

也添加这个字体文件
Bariol_Regular.otf
