Android - เราจะสามารถเช็คคลิ๊กลิงภายใน WebView ได้เปล่าครับ อยากตรวจสอบทุกครั้งที่คลิ๊ก

public class WebViewClicker extends Activity implements OnTouchListener, Handler.Callback {

private static final int CLICK_ON_WEBVIEW = 1;
private static final int CLICK_ON_URL = 2;

private final Handler handler = new Handler(this);

private WebView webView;
private WebViewClient client;

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

    webView = (WebView)findViewById(R.id.web);
    webView.setOnTouchListener(this);

    client = new WebViewClient(){ 
        @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { 
            handler.sendEmptyMessage(CLICK_ON_URL);
            return false;
        } 
    }; 

    webView.setWebViewClient(client);
    webView.setVerticalScrollBarEnabled(false);
    webView.loadUrl("http://www.example.com");
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if (v.getId() == R.id.web && event.getAction() == MotionEvent.ACTION_DOWN){
        handler.sendEmptyMessageDelayed(CLICK_ON_WEBVIEW, 500);
    }
    return false;
}

@Override
public boolean handleMessage(Message msg) {
    if (msg.what == CLICK_ON_URL){
        handler.removeMessages(CLICK_ON_WEBVIEW);
        return true;
    }
    if (msg.what == CLICK_ON_WEBVIEW){
        Toast.makeText(this, "WebView clicked", Toast.LENGTH_SHORT).show();
        return true;
    }
    return false;
}
}
