I am fetching information from the website in JSON Format and displaying that info into my app using AsynTask. The Problem is that on On First time my Progress dialog shows well and hide after loading contents into app. But When i use Scroll-view to load more then progress dialog appears and hide after loading immediately at the same time progress dialog opens again and not hiding and Scroll-View loads data one more time in the background.I want only one time to load data after each using Scroll-View to load more. Progress Dialog is not hiding and It keeps running my app. I am struck at this point.
Basically i noticed that My Scroll-View indicator collide two times on the bottom due to this scroll-View trigger two times. How can i stop it and restrict this only one time after each scrolling.
And one more thing wanna share that everything is working awesome in Froyo 2.2 and not working in 2.3 to 4.2. Kindly help me on this. Thanks in advance.

I have Solved this issue and want to share with the future readers. I made a switch and add cases now the new Scroll-View trigger can not run until the previous data will not complete loads.
Here is the final code and hope will help you friends. Thanks

Starting from API level JELLY_BEAN_MR1 and above, only methods explicitly marked with the #JavascriptInterface annotation are available to the Javascript code.
You just need to add this above your showHTML method e.g:
class JavaScriptInterface{
#JavascriptInterface
public void showHTML(String html) {
m_nHTMLSize = 0;
if (html !=null) {
//int i = html.lastIndexOf(""); //search for something in the text
m_nHTMLSize = html.length();
Log.d(LOG_TAG, "HTML content is: "+html+"\nSize:"+m_nHTMLSize+" bytes");
}
}
}
Also need to remove window from you JS call:
m_web.loadUrl("javascript:window.HTMLOUT.showHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
to
m_web.loadUrl("javascript:HTMLOUT.showHTML('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");

Hi I have an Activity which user open upon click on a TAB. Actually I have a ViewGroup and Tabactivity as Main Activity. on the first tab I have three activity.
Now in an activity I have a list view (custom) populating on Oncreate and a ViewFlipper (only adding view) in Onresume using AsyncTask.
In that asynctask in Pre Execute if I add code for loader it gives error. Also If I do not show the loader the screen is freezing until the Async task finished.
I actually want to load the list view first and then in background run the async task with a loader. Also does not want to freeze the screen.
Here Is My Acivity

I have a question, as I can get all the data that has been inserted into the edit text? the edit text is on a loop, I need a way to get those values and work with them, try using an array but I get errors. could help me? any idea? Help!
package com.example.test;

public class MainActivity extends Activity {
public static final String TAG = MainActivity.class.getSimpleName();
#Override

try {
numberOfControlsToGenerate = Integer.parseInt(count.getText().toString().trim());
} catch (NumberFormatException e) {
Log.e(TAG, e.getMessage(), e);
}
if (numberOfControlsToGenerate > 0) {
if (container.getChildCount() > 0) {
container.removeAllViews();
}
for (int counter = 0; counter < numberOfControlsToGenerate; counter++) {
addEditText(container);
}
}
}
});
}
private void addEditText(LinearLayout container) {
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
EditText editTextToAdd = new EditText(this);
editTextToAdd.setLayoutParams(params);
container.addView(editTextToAdd);
}
}
You can create multiple edittext by using array.
public class MainActivity extends Activity{
EditText[] sample_et;
int numberOfControlsToGenerate = 10;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_layout);
LinearLayout root_layout = (LinearLayout)findViewById(R.id.root);
sample_et = new EditText[numberOfControlsToGenerate];
//numberOfControlsToGenerate is decleres statically you can get the count from edit text
for(int i = 0; i < count; i++ ){
sample_et[i] = new EditText(this);
root_layout.addView(sample_et[i]);
}
}
}
Add setTag when you create dynamic EditText
add line in addEditText(LinearLayout container) method
private void addEditText(LinearLayout container) {
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
EditText editTextToAdd = new EditText(this);
editTextToAdd.setLayoutParams(params);
editTextToAdd.setTag(editTextToAdd); //Add this Line
container.addView(editTextToAdd);
}
Write code onClick listener on any Button
getvalue.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
for (int i = 0; i < container.getChildCount(); i++) {
if(container.getChildAt(i) instanceof EditText) {
EditText et = (EditText) container.getChildAt(i).getTag();
if(et != null) {
Log.i("<Tag Name>", et.getText().toString());
}
}
}
}
});
In my application , I am dynamically generating a linearlayout that contains an edittext and some Buttons .
I want that when the user presser the 'enter' on the keyboard of device the keyboard should hide
I tried it by setting the input type of the edittext , But by this when the user presses "enter" it moves onto another edittext .
How can i do that??
