java - 因此，我正在使用此应用程序，它没有显示任何错误并已成功安装，但运行后便崩溃了

Question

这是我正在处理的代码，我应该再次提及它在Log cat中没有显示任何错误，并显示安装成功，但启动后便崩溃了。我还提供了Manifest，Gradle和布局代码，以防它们可能出现一些错误。

Answer 1

我至少看到一个错误。您没有为 Activity 设置布局资源:

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            // setContentView is missing here
            init();
        }

将其他 setContentView(R.layout.activity_splash_screen);方法中的 onCreate行粘贴到上述方法中。
