How to make the webChromeClient()calss's callbacks handles and listen to a button?
The problem I have is that, I have a button and anedittext field, both of them are in a RelativeLayout and the webView is layed-out above them so I can avoid mixing the contents of the displayed webpage with both of the buttonand edittext. The purpose of having an edittext field is to allow the user to enter a webpage name. And the purpose of having a button is to launch the webpage the user have entered. I also use webClientView class and a toast inside the callback onPageFinished to notify me whenever the webpage finishes loading. But whenever I press the button to launch the a webpage specified in the edittext field, the callback onPageFinish is always called even BEFORE the webpage finishes loading. For an example, if I specified a website address in the edittext and pressed the button repeatedly, I will get the toast output as much as the number of pressings on the button. Please refer to my question I posted here which is almost regarding the same issue. despite it solved my problem partially, when I was coding the demands of the App, I then realized that answers on my question I referenced here are seamed and or not sufficient. Is there any way to solve that issue using the webChromeView class? and how?
JavaCode:
OnClickListener btnGoListener = new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
webView00.loadUrl(etUrl.getText().toString());
webView00.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
Toast.makeText(getBaseContext(), "Loading Finished 2", Toast.LENGTH_LONG)
.show();
}
});
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_web_page00);
webView00 = (WebView) findViewById(R.id.webView00);
btnGo = (Button) findViewById(R.id.go_btn);
etUrl = (EditText) findViewById(R.id.url_edittext);
webView00.getSettings().setJavaScriptEnabled(true);
webView00.setWebChromeClient(new myWebChromeClient());
btnGo.setOnClickListener(btnGoListener);
webView00.loadUrl("http://google.com");
webView00.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String url) {
Toast.makeText(getBaseContext(), "Loading Finished 1", Toast.LENGTH_LONG)
.show();
}
});
}
public class myWebChromeClient extends WebChromeClient {
}
