任何人都可以帮我解决这个问题吗？

我尝试了您的代码并看到 MainActivity 在 SplashActivity 中单击跳过按钮后打开时，系统会启动绘制状态栏，但不会立即启动，因为它正在打开一些动画，直到那时 MainActivity 布局让整个画面画布自己绘制。在尝试几分钟修复主题或样式后，我没有成功，我想出了一个黑客，显示状态在开始 MainActivity 之前的栏，以便 MainActivity 的布局不会获得用于绘制的全屏画布。

你也可以试试这个黑客。

public class SplashScreenActivity extends AppCompatActivity {

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

        setContentView(R.layout.splash);

        findViewById(R.id.txt_skip).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (Build.VERSION.SDK_INT > 16) {
                    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
                }
                else {                       
                    int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
                    getWindow().getDecorView().decorView.setSystemUiVisibility(uiOptions);
                }                
                startActivity(new Intent(SplashScreenActivity.this, MainActivity.class));
            }
        });
    }
}

希望这会对你有所帮助。如果这解决了您的问题，请告诉我？
