谁能帮我解决这个问题？？

我试过你的代码，发现当 MainActivity 在 SplashActivity 中点击跳过按钮后打开时，系统开始绘制状态栏但不是立即，因为它正在打开一些动画，直到 MainActivity 布局让整个屏幕 Canvas 自行绘制。在尝试修复主题或样式几分钟后，我没有成功，我想出了一个 hack，显示状态在开始 MainActivity 之前设置栏，这样 MainActivity 的布局就不会获得全屏 Canvas 来绘制自身。

您也可以试试这个 hack。

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));
            }
        });
    }
}

希望对您有所帮助。让我知道这是否解决了您的问题？
