【中文标题】当我按下一个按钮时，“不幸的是我的应用程序已停止”[重复]【英文标题】："Unfortunately MyApp has stopped" when I Press A Button [duplicate] 【发布时间】：2018-11-04 20:58:23 【问题描述】：我用我在 github 上找到的代码制作了一个问答游戏，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。我在没有其他课程的情况下尝试过，但它仍然崩溃。有我的 MainActivity 类，MainActivity xml 和 androidManifest。
MainActivity.java
package com.proje.bilgiyarismasi.bilgiyarismasi;

import android.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();
);

感谢您的帮助。
【问题讨论】：
只添加logcat的异常部分 尝试在 playButton 中从android:layout_alignBottom="@+id/baslatButonu" 中删除 + 符号
学习调试，youtube上有很多视频。学习为无法调试的错误发布崩溃 logcat。
阅读此内容以获取 +id 和 id ***.com/a/5025971/8089770
【参考方案1】：
您没有正确投射图像按钮。
在onCreate()中使用它
baslat = (ImageButton)findViewById(R.id.baslatButonu);
ayarlar =(ImageButton) findViewById(R.id.ayarlarButonu);
并在清单中声明此活动
<activity android:name=".Ayarlar">
来自日志猫
**java.lang.RuntimeException: Font asset not found fonts/Bariol_Regular.otf**
也添加这个字体文件 Bariol_Regular.otf
请检查此链接 How to use custom font in Android Studio
【讨论】：
在新的 android studio 中不需要铸造。我认为活动名称是 MAinActivity 不是吗？ 是的，你是对的，不能说@Kangaetemo 正在使用 In 3.0 with sdk 26 :) 对不起，我忘了补充说我使用的是 2.3.3。感谢您的回答，但游戏仍然崩溃，我在 logcat 上看不到任何新内容 java.lang.RuntimeException: Unable to start activity 如果您还没有添加，请在清单中声明此活动 和 java.lang.RuntimeException: 找不到字体资源 fonts/Bariol_Regular.otf以上是关于当我按下一个按钮时，“不幸的是我的应用程序已停止”[重复]的主要内容，如果未能解决你的问题，请参考以下文章
