如何在调用后刷新从 Android tabview 调用的 webview，例如，如果我调用与 tabview 连接的活动，那么一旦调用它就不会刷新。有什么办法可以做到这一点，

代码：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    TabHost tabHost = getTabHost(); 

    tabHost.addTab(createTab1(aActivity.class, "a", "", R.drawable.ic_tab_a));
    tabHost.addTab(createTab2(bActivity.class, "b", "", R.drawable.ic_tab_b));
    tabHost.addTab(createTab3(cActivity.class, "c", "", R.drawable.ic_tab_c));  
    tabHost.setCurrentTab(0);
}

Call again

mWebView.loadUrl("http://www.websitehere.php");

所以完整的代码将是

newButton.setOnClickListener(new View.OnClickListener() {

  public void onClick(View v) {
dgeActivity.this.mWebView.loadUrl("http://www.websitehere.php");
  }});

我在堆栈溢出上找到了这个答案。它应该肯定可以工作。

或者尝试这个

实现一个 WebViewClient，覆盖 shouldOverrideUrlLoading() 来告诉 Android 你想要什么通过 setWebViewClient() 将 WebViewClient 附加到 WebView。

Call again

mWebView.loadUrl("http://www.websitehere.php");

so the full code would be

newButton.setOnClickListener(new View.OnClickListener() {

  public void onClick(View v) {
dgeActivity.this.mWebView.loadUrl("http://www.websitehere.php");
  }});

I found this answer on stack overflow.And it should work for sure.

or try this one

Implement a WebViewClient, overriding shouldOverrideUrlLoading() to tell Android what you want to do on link clicks. Attach that WebViewClient to the WebView via setWebViewClient().
