Question

我正在尝试实现基本的webview。但是，当我输入网址并点击按钮加载它时，我会弹出一个弹出窗口，要求我从应用程序列表中选择加载该网页。然后网页在浏览器中完美加载。我已添加了INTERNET权限清单文件。请帮我发现错误或遗漏逻辑。

public class MainActivity extends Activity {

private static final String TAG = "WebViewActivity";
Button button1;
EditText et1;
String address;
WebView wv1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    button1=(Button)findViewById(R.id.button1);
    et1=(EditText)findViewById(R.id.editText1);
    wv1=(WebView)findViewById(R.id.webView1);
    wv1.getSettings().setJavaScriptEnabled(true);

    button1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            address=et1.getText().toString();
            Log.d(TAG,"url has been stored in address");
            wv1.loadUrl(address);
            Log.d(TAG,"url should now be loaded in webview");


        }
    });

}

Answer 1

请设置setWebViewClient监听器：

webview.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url){
        // do your handling codes here, which url is the requested url
        view.loadUrl(url);
        return false; 
   }
});

现在用您的代码替换此代码......

  public class MainActivity extends Activity {

        private static final String TAG = "WebViewActivity";
        Button button1;
        EditText et1;
        String address;
        WebView wv1;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            button1=(Button)findViewById(R.id.button1);
            et1=(EditText)findViewById(R.id.editText1);
            wv1=(WebView)findViewById(R.id.webView1);
            wv1.setWebViewClient(new MyBrowser());
            wv1.getSettings().setJavaScriptEnabled(true);

            button1.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    address=et1.getText().toString();
                    Log.d(TAG,"url has been stored in address");
                    wv1.loadUrl(address);
                    Log.d(TAG,"url should now be loaded in webview");


                }
            });

        }

        private class MyBrowser extends WebViewClient {

           @Override
           public boolean shouldOverrideUrlLoading(WebView view, String url) {
               view.loadUrl(url);
               return true;
           }

           @Override
           public void onPageFinished(WebView view, String url) {

           }
       }
