Oppo F1和LG G2运行棒棒糖有一个问题。在运行Lollipop的其他设备上，问题不会出现
我的问题是文件选择器没有显示上述设备。
我目前正在做的事情：
private WebView web;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_add_event);
web = (WebView) findViewById(R.id.webView_addEvent);
web.loadUrl(tempURL);
startWebViewForLolipop();
}
private void startWebViewForLolipop() {
//CODING FOR LOLIPOP VERSION
// Create new webview Client to show progress dialog
// Called When opening a url or click on link
// You can create external class extends with WebViewClient
// Taking WebViewClient as inner class
web.setWebViewClient(new WebViewClient() {
// ProgressDialog progressDialog;
//If you will not use this method url links are open in new brower not in webview
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// Check if Url contains ExternalLinks string in url
// then open url in new browser
// else all webview links will open in webview browser
if (url.contains("google")) {
// Could be cleverer and use a regex
//Open links in new browser
view.getContext().startActivity(
new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
// Here we can open new activity
return true;
} else {
// Stay within this webview and load url
view.loadUrl(url);
return true;
}
}
//Show loader on url load
public void onLoadResource(WebView view, String url) {
// if url contains string androidexample
// Then show progress Dialog
/* if (progressDialog == null *//*&& url.contains("androidexample")*//*
) {
// in standard case YourActivity.this
progressDialog = new ProgressDialog(AddEvent.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
}*/
}
