androidwebview空白

㈠ 個人是做android使用Webview載入H5的時候，網路圖片顯示不出來，是空白的

是不是你的android工程的編譯版本太低了，切換到4.4的試試看。我就遇到過這樣的情況，有些webview的方法被禁止了，導致無法顯示。

㈡ android開發 webview點擊空白處刷新怎麼處理

方法一：

webView.setWebViewClient(new WebViewClient(){

@Override

public boolean shouldOverrideUrlLoading(WebView view, String url) {

view.loadUrl(url); //在當前的webview中跳轉到新的url

return true;

}

});

方法二：

mWebView.goBack(); //後退

mWebView.goForward();//前進

mWebView.reload(); //刷新

//點擊後退按鈕,讓WebView後退一頁(也可以覆寫Activity的onKeyDown方法)

webview.setOnKeyListener(new View.OnKeyListener() {

@Override

public boolean onKey(View v, int keyCode, KeyEvent event) {

if (event.getAction() == KeyEvent.ACTION_DOWN) {

if (keyCode == KeyEvent.KEYCODE_BACK && webview.canGoBack()) { //表示按返回鍵

時的操作

webview.goBack(); //後退

//webview.goForward();//前進

return true; //已處理

}

}

return false;

}

});

㈢ Android設代理通過webView連接Gmail登錄時，怎麼除掉「loading,please wait...」提示空白頁的顯示

看了下，在登錄的過程中一共跳轉了這么多個url，也就是說登錄的過程中需要和客戶端進行多次交互，解決思路就是重寫shouldOverrideUrlLoading(WebView view, String url) 方法，把中間這些url全部攔截下來，這樣就能夠不顯示，同時你也可以完成一些自定義的操作。
