I have two Fragments. First Fragment is named as Fragment1 and Second Fragment named as physics. First Fragment have Two Buttons. I would Like to show a local html page ( say A.html when Button1 is pressed and B.html when Button2 is Pressed ) in Second Fragment i.e in physics.java
My Fragment.java contains following code

Here I have provided code for one activity (Activity1), write code for other activities like Activity2, Activity3 etc.
I have created widget. I am trying to update the widget in background each 5 seconds (For testing purpose 5 second). But it is not getting update.Is any mistake on my code.

YES. you are doing it wrong.
the minimum available value for updatePeriodMillis is 30min (1800000 millis).
official document :
Note: Updates requested with updatePeriodMillis will not be delivered more than once every 30 minutes.
i'm trying to make a webview app which can display two website in one screen. but when i run my app it display one website and open on new browser. how can i display two website and it doesn't work on new browser?
this is my WebViewActivity class:
package com.mkyong.android;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WebViewActivity extends Activity {
private WebView webView1, webView2;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView1 = (WebView) findViewById(R.id.webView1);
webView1.getSettings().setJavaScriptEnabled(true);
webView1.loadUrl("http://www.google.com");
webView2 = (WebView) findViewById(R.id.webView2);
webView2.getSettings().setJavaScriptEnabled(true);
webView2.loadUrl("http://www.google.com");
}
}
this is my xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<WebView
android:id="#+id/webview1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.39" />
<WebView
android:id="#+id/webview2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.53" />
</LinearLayout>
I suggest you use framelayout and try to set webviewClient to your webview
this function shouldOverrideUrlLoading (in the declaration of the webviewClient)
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
Log.i("Page", url);
view.setWebViewClient(new MyWebViewClient());
view.setWebChromeClient(new MyWebChromeClient());
view.loadUrl(url);
return true;
}
will override url loaded by the webview and force it to be loaded in the webview not in the new browser
I am new to android ,I want make an app which needs a progress bar, but the code which I wrote seems to crash each time I run it .As till now I am unable to find the bug.I am using a vertical progress bar.
thanx in advance.
package com.example.progtask;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ProgressBar;
public class MainActivity extends Activity implements OnClickListener, Runnable {
private ProgressBar pb;
private Button show;
private Button hide;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pb = (ProgressBar) findViewById(R.id.progressBar1);
show = (Button) findViewById(R.id.button1);
hide = (Button) findViewById(R.id.hide);
// pb.setVisibility(ProgressBar.GONE);
show.setOnClickListener(this);
hide.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.equals(show)) {
pb.setVisibility(ProgressBar.VISIBLE);
pb.setProgress(0);
pb.setMax(12);
new Thread(this).start();
} else {
pb.setVisibility(ProgressBar.GONE);
}
}
#Override
public void run() {
// TODO Auto-generated method stub
int n = 0;
while (n < 10) {
n++;
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
pb.setProgress(n);
}
}
Below is the Xml file
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent" >

Try this
#Override
public void onClick(View v) {
switch (v.getId())
{
case R.id.button1:
pb.setVisibility(ProgressBar.VISIBLE);
pb.setProgress(0);
pb.setMax(12);
new Thread(this).start();
break;
case R.id.hide:
// do the needful.
break;
}
}
This is how it worked:
public class MainActivity extends Activity implements OnClickListener, Runnable {
private ProgressBar pb;
private Button show;
private Button hide;
int n;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
pb = (ProgressBar) findViewById(R.id.progressBar1);
show = (Button) findViewById(R.id.button1);
hide = (Button) findViewById(R.id.button2);
// pb.setVisibility(ProgressBar.GONE);
show.setOnClickListener(this);
hide.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId())
{
case R.id.button1:
pb.setVisibility(ProgressBar.VISIBLE);
pb.setProgress(0);
pb.setMax(100);
n = 0;
new Thread(this).start();
break;
case R.id.button2:
// do the needful.
pb.setVisibility(ProgressBar.GONE);
break;
}
}
#Override
public void run() {
// TODO Auto-generated method stub
int n = 0;
while (n < 100) {
n++;
try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}pb.setProgress(n*10);
}
pb.setProgress(n*10);
}
}
the xml file is:
