如何设置的WebView客户端？ [英] How to set webview client?

问题描述

我在你采用Android文档看出

I seen in android documentation where you use

 private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

要处理时，项目一个web视图中点击。

To handle when items are clicked within a webview.

唯一的问题是我的，是即时通讯设置URL的另一种方法。

The only problem is with me, is that im setting the url in another method.

该HelloWebViewClient将覆盖并且不使用，用户可以从选择的网址。它只是返回null..How可我在骑这种方法使用的URL由用户设置？

The HelloWebViewClient overrides that and doesnt use the url that the user can chose from. It just returns null..How could i over ride this method to use the url set by the user?

当我用它在一个普通的方法与的WebView浏览器的URL被加载; 然后 browser.loadUrl（字符串URL）

The URL is loaded when i use it in a regular method with the WebView browser; and then browser.loadUrl(String url)

@Override
public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.shopping);

    findIT = (Button)findViewById(R.id.findIT);
    edittext = (EditText)findViewById(R.id.item);
    type = (RadioGroup)findViewById(R.id.console);
    site = (RadioGroup)findViewById(R.id.shopping_group);

    findIT.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            item = edittext.getText().toString();
                lookUp();
        }
    });

}

public void lookUp(){

    browser = (WebView) findViewById(R.id.shoppingBrowser);
    browser.getSettings().setJavaScriptEnabled(true);
    Log.v(item, item);
    getUserPreference();
    browser.setWebViewClient(new HelloWebViewClient());
    browser.loadUrl(url);


}



  private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String notuse) {
        Log.v("shopping", url+" loaded");



       return true;
    }


  }
public void getUserPreference(){

    switch(type.getCheckedRadioButtonId()){
    case R.id.item:
        console = "item";
        break;
    case R.id.PS3:
        console = "item";
        break;
    case R.id.item:
        console = "item"; 
        break;

    }Log.v("item", console);
     switch(site.getCheckedRadioButtonId()){

         case R.id.store:
             url = "http://www.gamestop.com/browse?nav=16k- "+ item +"  " + console;
             break;
         case R.id.store:
             url = "http://www.google.com/search?q="+item + "   " + console+"&tbm=shop&hl=en&aq=0&oq=where+";
             break;
         case R.id.store:
             url = "http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Dvideogames&field-keywords="+item + "  "+ console+"&x=0&y=0"; 
             Log.v("shopping", url);
          }
       }
  }

如果你看到什么即时试图做的用户开始选择他们想从开店哪个网站。并从那里我将它的网址。

If you see what im trying to do the user gets to select what site they want to shop from. and from there i set it to the url.

推荐答案

如果用户是从同一个活动选择的网址，你可以只从成员变量，而不是从参数中的URL引用网址：

If the user is choosing the URL from the same activity you can just reference the URL from the member variable instead of the URL from the parameter:

// Member variable stored to reflect user's choice
private String mUserUrl = "http://stackoverflow.com";

private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        // This line right here is what you're missing.
        // Use the url provided in the method.  It will match the member URL!
        view.loadUrl(url);
        return true;
    }
}

这告诉你超载的URL装载WebviewClient（事实上导致其加载您希望提供的网址，而不是URL）。

This tells the WebviewClient that you've overloaded the URL loading (and in fact caused it to load the URL that you wish instead of the url supplied).

下面是一些我嘲笑了一个完整的例子：

Here is a complete example of something I mocked up:

public class HelloWebViewActivity extends Activity {
    private WebView mWebView = null;
    private EditText mInputUrl = null;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mInputUrl = (EditText)findViewById(R.id.input_url);
    Button button = (Button)findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
              String url = mInputUrl.getText().toString();
              mWebView.loadUrl(url);
            }
        });

    mWebView = (WebView) findViewById(R.id.webview);
    mWebView.getSettings().setJavaScriptEnabled(true);
    mWebView.setWebViewClient(new HelloWebViewClient());
}

private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
    view.loadUrl(url);
    return true;
    }
}
}
