你可以这样做
webView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (url.equals("alert://alert")) {
Toast.makeText(this, "alert", Toast.LENGTH_LONG).show();
} else if (url.equals("choose://image")) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, FILECHOOSER_RESULTCODE);
}
return true;
}
});
