activity_maian.xml

此代码可在仿真器上完美运行，但不能在实际设备上运行，并且由于SwipeRefreshLayout我无法向下滚动，因此在滚动时始终排在中间，请帮助我解决此问题

预先感谢！

这是MainActivity，我给出了一个普通的刷卡刷新布局代码，该代码可在模拟器中使用，但不能在实际设备中使用。.

MainActivity.java

 @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        swipe = (SwipeRefreshLayout) findViewById(R.id.swipe);
        swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                LoadWed();
            }
        });
        LoadWed();

 public void LoadWed(){
        webView = (WebView) findViewById(R.id.webView);
        webView.setWebViewClient(new myWebClient());
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setAppCacheEnabled(true);
        swipe.setRefreshing(true);
        webView.loadUrl("https://localhost/admin");
        webView.getSettings().setDomStorageEnabled(true);

        swipe.setColorSchemeResources(android.R.color.holo_blue_bright,
                android.R.color.holo_green_light,
                android.R.color.holo_orange_light,
                android.R.color.holo_red_light);
    }

将FrameLayout添加为DrawerLayout的第一个子项。并添加了TextView，ProgressBar，SwipeRefreshLayout作为该FrameLayout的子级，现在它可以按预期工作。

SwipeRefreshLayout在实际设备上不起作用，仅在模拟器上起作用
