任何人都可以帮我解决这个问题？

我想你的代码，并看到，当MainActivity是开放跳过按钮单击SplashActivity后，系统开始绘制状态栏，但不立即，因为它是在一些动画打开，到那时MainActivity布局得到整个屏幕的画布来绘制自己。在尝试了几分钟修复主题或样式后，我没有成功，我想出了一个黑客，在启动之前显示状态栏MainActivity，以便MainActivity' s布局不会获取全屏画布来绘制自己。

你也可以试试这个破解。

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)); 
      } 
     }); 
    } 
} 

希望这有助于你。让我知道这是否解决了你的问题？
