Improve this questioni want to open twitter auth in my webview rather then opening in browser, any good tutorial how to play with webview in dialog and loading it inside dialog?
You can just apply dialog theme to regular activity which contains a WebView.
Context mContext = this;
AlertDialog.Builder alert = new AlertDialog.Builder(mContext);
alert.setTitle("Riga");
WebView wv = new WebView(mContext);
String html = "<html><body>some html here</body></html>";
wv.loadData(html, "text/html", "UTF-8");
alert.setView(wv);
alert.setIcon(R.drawable.icon);
alert.setPositiveButton("Yes", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int id){
Toast.makeText(getApplicationContext(), "Success", Toast.LENGTH_SHORT).show();
}
});
alert.setNegativeButton("No", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int id){
Toast.makeText(getApplicationContext(), "Fail", Toast.LENGTH_SHORT).show();
}
});
alert.show();
Open like dialog and register in Manifest.xml file. Use like Dialog box.
