Re: [android-developers] Re: How to show a loading image or an animation?

[Temitope Akinwande]

So here is an example I created by following this tutorial
http://developer.android.com/intl/fr/guide/topics/ui/dialogs.html
under the heading "Example ProgressDialog with a second thread"

I modified it a little to load a webpage and use the progress of the
page to display/dismiss the dialog


package com.test.progressdialog;

import android.app.Activity;
import android.app.Dialog;
import android.app.ProgressDialog;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.widget.Button;

public class ProgressDialogTest extends Activity {
static final int PROGRESS_DIALOG = 0;
ProgressThread progressThread;
ProgressDialog progressDialog;

private Button mButton;
private WebView mWebView;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

mButton = (Button) findViewById(R.id.progressDialog);
mWebView = (WebView) findViewById(R.id.content);
mButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mButton.setVisibility(View.GONE);
mWebView.loadUrl("http://en.m.wikipedia.org/wiki/::Home";);
showDialog(PROGRESS_DIALOG);
}
});
}

protected Dialog onCreateDialog(int id) {
switch(id) {
case PROGRESS_DIALOG:
progressDialog = new
ProgressDialog(ProgressDialogTest.this);
progressDialog.setMessage("Loading...");
progressDialog.setIndeterminate(true);
progressThread = new ProgressThread(handler);
progressThread.start();
return progressDialog;
default:
return null;
}
}

// Define the Handler that receives messages from the thread
and update the progress
final Handler handler = new Handler() {
public void handleMessage(Message msg) {
int total = msg.getData().getInt("total");
if (total >= 100) {
dismissDialog(PROGRESS_DIALOG);
progressThread.setState(ProgressThread.STATE_DONE);
}
}
};

/** Nested class that performs progress calculations (counting) */
private class ProgressThread extends Thread {
Handler mHandler;
final static int STATE_DONE = 0;
final static int STATE_RUNNING = 1;
int mState;

ProgressThread(Handler h) {
mHandler = h;
}

public void run() {
mState = STATE_RUNNING;
//total = 0;
while (mState == STATE_RUNNING) {
try {
Thread.sleep(100);
} catch (InterruptedException e) {
Log.e("ERROR", "Thread Interrupted");
}
Message msg = mHandler.obtainMessage();
Bundle b = new Bundle();
b.putInt("total", mWebView.getProgress());
msg.setData(b);
mHandler.sendMessage(msg);
}
}

/* sets the current state for the thread,
 * used to stop the thread */
public void setState(int state) {
mState = state;
}
}
}


Hopefully that helps you in your task.

[Achanta]

I saw that tutorial earlier and have also tried it.

Yes for now even a progress dialog in that way works for me.
I know i need to use getProgress but do not know how to send the
progress to the thread running the progress dialog.

Thanks again.

Re: [android-developers] Re: How to show a loading image or an animation?

[Temitope Akinwande]

I found this tutorial

http://www.helloandroid.com/tutorials/using-threads-and-progressdialog

What you can try to do and see if it works is to create a new thread
on button click so that when the page is loading, you can display an
indeterminate progress dialog while you are waiting on the page to be
done loading using Webview's getProgress() method
http://developer.android.com/intl/fr/reference/android/webkit/WebView.html#getProgress()
.

Create a handler so that when the page is done loading, you can
dismiss the dialog.
Hope that helps you(see the tutorial).

[Achanta]

Thank you for the reply,

> as I'm sure this question has been asked before.
I was also sure that it has been asked before because its a common
task, But searching the web or this group did not give me the
appropriate results.

> From what I gather, you'll have to start a thread using AsyncTask and
> that way you can show your progress dialog.
I may have to but I am not sure. Here I am loading a webpage and this
is happening in the same thread or it appears to be. I can also get
the progress of it from the WebView. I am not doing any background
activity like calculations or downloading stuff, but loading the page
which is on the same thread. So I am a little lost on how to get this
done.

Thanks again.
