How to add spinner loading for every pags loading in webview

How to add spinner loading for every pags loading in webview - java

I am a beginner and building webview app with splash screen in AIED.
I want to add spinner loading for every page loading in webview. I mean when this webview loads after the splash screen, I can see home page of website when I open any other page. While loading that page I want to show spinner in the center of screen. When the page load the spinner should disappear.
I not know where to add the specific code.
Here is mainactivity.java

Here is activity main.xml

android:layout_width="fill_parent"
android:visibility="gone"
android:src="#drawable/image_1"/>
<WebView

android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_width="match_parent"

</RelativeLayout>

Big Caveat: This solution won't completely hide the white screen(loading) on websites that has to download and load .js files especially if they are big.
First, you are using onPageFinished incorrectly. onPageFinished is always going to be called after every page load has finished. This means if you are navigating on your website, it will call onPageFinished every after you navigate a URL and the webview has finished loading it.
Here's an idea on how to do this:
First create an HTML page and design on how you want your spinner would look like. Save the HTML template as a string HTMLSpinner.
Then create a second webview and load the HTML template string to it
public WebView spinner;
spinner.loadData(HTMLSpinner, "text/html", "UTF-8");
Then modify your main mWebView.setWebViewClient like this
mWebView.setWebViewClient(new WebViewClient(){
#Override
public void onPageStarted(WebView view, final String url, Bitmap favicon) {
mWebView.setVisibility(View.GONE);
spinner.setVisibility(View.VISIBLE);
// YOUR LANDING PAGE
if(url.equals("https://www.mominbaba.com")){
mWebView.setVisibility(View.GONE);
mSplashView.setVisibility(View.VISIBLE);
}
}
#Override
public void onPageFinished(WebView view, String url) {
mWebView.setVisibility(View.VISIBLE);
spinner.setVisibility(View.GONE);
// YOUR LANDING PAGE
if(url.equals("https://www.mominbaba.com")){
mWebView.setVisibility(View.GONE);
mSplashView.setVisibility(View.VISIBLE);
}
}
});
That should swap the current webview that you see from the main webview to the loader. I have chosen to use a second webview because the asset that was given to was an animated SVG.

How to Allow Calls on Button Click in Android Web View App?

I am new and still learning basics. Please help me to allow the phone calls in webview on this activity. So when someone clicks on phone number it should call, thanks.

This is How it works for me:
package com.example.myapplication;
import android.net.Uri;
import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.app.Activity;
import android.content.Intent;
public class MainActivity extends Activity {
private static final String TEL_PREFIX = "tel:";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView wv = (WebView) findViewById(R.id.webview);
wv.setWebViewClient(new CustomWebViewClient());
wv.loadUrl("https://google.pk");
WebSettings webSettings = wv.getSettings();
webSettings.setJavaScriptEnabled(true);
}
private class CustomWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView wv, String url) {
if(url.startsWith(TEL_PREFIX)) {
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse(url));
startActivity(intent);
return true;
}
return false;
}
}
}

First you would need to bind your javascript code to your android code, this guide demonstrates how to do that. Then in your javascript, you could add a listener to your button that invokes a Java method.
Second, you need to integrate a calling solution into your app this guide explains what options you have and how you can implement them.
Once you implemented the calling solution, you could simply make a call from the Java method that you intend to invoke from your javascript.

How can I import an image from gallery and replace the one that in image view?

I built This App and i want that i can choose an image from gallery to replace the image view at the top. like the profil at facebook etc...
i tried the above code:
public class MainActivity extends Activity {
private static int RESULT_LOAD_IMAGE = 1;
Uri myPicture = null;
Button buttonLoadImage;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getting View
buttonLoadImage =(Button) findViewById(R.id.regButton);
buttonLoadImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, RESULT_LOAD_IMAGE);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
ImageView imageView = (ImageView) findViewById(R.id.regUserPhoto);
imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath));
}
}
in my phone with android 4.4.4: i can choose the image but when i press ok the app crash.
in emulator android 5.1.1: when i press the image the app crash

Why can't I use getActivity()

My question is why can't I use getActivity method in the following code. I'm trying to upload image with webView. It's my first Android application. I want to create an app for my classified osclass site.
When I build the app I get the following message:
error: cannot find symbol method getActivity().
Please change my code, and paste in Answer or write where should I put your code (or change).

You don't need to do getActivity() since you are already in the activity. You should just be able to do getApplicationContext()
