应用开发中需要获取WebView当前页面的标题，可能通过对WebChromeClient.onReceivedTitle()方法的重写来实现
效果图如下：
代码如下:
public class MainActivity extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
final TextView txtTitle = (TextView) findViewById(R.id.txtTitle);
final WebView webView = (WebView)findViewById(R.id.btnWebView);
WebChromeClient wvcc = new WebChromeClient() {
@Override
public void onReceivedTitle(WebView view, String title) {
super.onReceivedTitle(view, title);
Log.d("ANDROID_LAB", "TITLE=" + title);
txtTitle.setText("ReceivedTitle:" +title);
}
};
// 设置setWebChromeClient对象
webView.setWebChromeClient(wvcc);
// 创建WebViewClient对象
WebViewClient wvc = new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// 使用自己的WebView组件来响应Url加载事件，而不是使用默认浏览器器加载页面
webView.loadUrl(url);
// 消耗掉这个事件。Android中返回True的即到此为止吧,事件就会不会冒泡传递了，我们称之为消耗掉
return true;
}
};
webView.setWebViewClient(wvc);
final Button btnLoadWeb = (Button)findViewById(R.id.btnLoadWeb);
btnLoadWeb.setOnClickListener(new Button.OnClickListener(){
public void onClick(View v){
webView.loadUrl("http://www.baidu.com");
}
});
}
}
