I'm working on a custom html browser using WebView.loadData(). I'm
trying to implement a back button feature, but it seems that loadData
doesn't update the history, and I have no way to do it myself.
private WebView wv;
private boolean goBack = false;
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
wv = (WebView)findViewById(R.id.record_html);
wv.setOnKeyListener(this);
wv.loadData("<html><body>Test!</body></html>", "text/html",
"utf-8");
}
boolean onKey(View v, int keyCode, KeyEvent event)
{
if (keyCode == KeyEvent.KEYCODE_BACK && event.getAction() ==
KeyEvent.ACTION_DOWN)
{
if (goBack)
{
if (wv.canGoBack())
{
wv.goBack();
goBack = !goBack;
return true;
}
}
else
{
goBack = !goBack;
wv.loadData("<html><body>Test 2!</body></html>","text/html",
"utf-8");
return true;
}
}
return false;
}
I would expect this to first load "Test!". When I press the back
button, it loads "Test2!" (this part works), and sets goBack to true.
Then I press the back button again, and it sees that it can goBack,
and loads "Test!" again. Instead, canGoBack() returns false.
I've tried adding a WebViewClient and calling doUpdateVisitedHistory,
but that is asking for a URL and doesn't accept data.
Is there another way of doing this, or am I going to have to create a
list of HTML to cycle through?
