Question

我正在创建一个在我的播放器死亡时出现的新菜单。活动未加载，应用程序在下面指示的行崩溃。我所有的其他活动都非常好，我尽可能地遵循其他活动，但它仍然无法正常工作。

活动类：

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();
    }
}

       android:layout_centerHorizontal="true"
       android:onClick="onClick"
       android:background="@drawable/mainmenu_button" />

</RelativeLayout>

任何帮助或提示指出我正确的方向将不胜感激！感谢

在堆栈跟踪中，原始问题是

引起：java.lang.OutOfMemoryError：无法分配带有16777168个空闲字节的58286092字节分配和52MB直到OOM

这听起来像是一个如此大的图像，你的设备没有足够的内存来创建它。尝试从活动布局的根视图中删除此行：

android:background="@drawable/death_screen"

如果您在删除此属性后可以成功运行应用程序，您就会知道问题是此图像占用了太多内存。那时，这个网站上有很多关于图像和内存消耗的问题/答案。

setContentView（）中的活动崩溃，布局有问题吗？
