android - Activity 在 setContentView() 中崩溃，布局有问题吗？

Question

我正在创建一个新菜单，该菜单会在我的玩家死亡时出现。该 Activity 未加载，应用程序在下面指定的行崩溃。我的所有其他 Activity 都运行良好，我尽我所能地尝试进行其他 Activity ，但仍然无法正常工作。

Activity 类:

public class DeathScreen extends Activity implements OnClickListener {
    //define buttons
    private Button btn_replay;
    private Button btn_menu;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //Hide title
        requestWindowFeature(Window.FEATURE_NO_TITLE);

        //Hide top bar
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.deathscreen);

        btn_replay = findViewById(R.id.btn_replay);
        btn_menu = findViewById(R.id.btn_menu);
    }

    //invoke callback event in view
    @Override
    public void onClick(View v) {
        Intent intent = new Intent();

        switch (v.getId())
        {
        case R.id.btn_replay:
            intent.setClass(this, GamePage.class);
            break;

        case R.id.btn_menu:
            intent.setClass(this, Mainmenu.class);
            break;
        }

        startActivity(intent);
    }

    @Override
    protected void onStart() {
        super.onStart();
    }

    @Override
    protected void onResume() {
        super.onResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
    }

    @Override
    protected void onStop() {
        super.onStop();
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
    }
}

在堆栈跟踪中，原始问题是

Caused by: java.lang.OutOfMemoryError: Failed to allocate a 58286092 byte allocation with 16777168 free bytes and 52MB until OOM

这听起来像是一张太大的图片，您的设备没有足够的内存来创建它。尝试从您的 Activity 布局的 Root View 中删除这一行:

android:background="@drawable/death_screen"

如果你删除这个属性后能成功运行应用，你就知道问题出在这张图片太耗内存了。那时，这个站点上有大量关于图像 + 内存消耗的问题/答案。
