mScrollView = (ScrollView) findViewById(R.id.scroll_view);
mScrollView.setSmoothScrollingEnabled(true);

// mGrid.setOnDragListener(new DragListener());
final LayoutInflater inflater = LayoutInflater.from(this);
for (int i = 0; i < NBR_ITEMS; i++) {
final View itemView = inflater.inflate(R.layout.item_grid, mGrid, false);
final TextView text = (TextView) itemView.findViewById(R.id.text);

System.out.println("size===" + size);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {

The layout where i want to create buttons dynamically
</LinearLayout>
</LinearLayout>
Code
if (NewDataSet.get("Table2") instanceof JSONArray) {
isDocPresent = true;
JSONArray array = NewDataSet.getJSONArray("Table2");
numOfDocCircles = array.length();
LayoutInflater layoutInflater;
Button button = new Button(context);
for (int k = 0; k < array.length(); k++) {
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(30, 30);
button.setLayoutParams(params);
button.setText("" + k);
llAddDocCircles.addView(button);
}
Error
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.
Please help me out whats the problem?

Move your button creation into the for loop, in your code you are basically just adding the same Button instance to the parent layout several times:
for (int k = 0; k < array.length(); k++) {
Button button = new Button(context);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(convertDpToPixel(30), convertDpToPixel(30));
button.setLayoutParams(params);
button.setText("" + k);
llAddDocCircles.addView(button);
}
Use below method to convert dp to pixel.
public static float convertDpToPixel(float dp){
Resources resources = context.getResources();
DisplayMetrics metrics = resources.getDisplayMetrics();
float px = dp * (metrics.densityDpi / 160f);
return px;
}

In your for loop call this method as:
for (int k = 0; k < array.length(); k++) {
llAddDocCircles.addView(addMoreButton("" + k));
}
And your addMoreButton() method is:
public Button addMoreButton(String text) {
Button button = new Button(context);
button.setId(buttonID);
LinearLayout.LayoutParams buttonLayoutParams = new LinearLayout.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
button LayoutParams.setMargins(10, 10, 10, 10); //Add this if you want margin of 10dp
button.setLayoutParams(buttonLayoutParams );
buttonArrayList.add(button);
buttonID++;
return button;
}
And you can easily access these button value by:
private static int buttonID = 0;
private ArrayList<Button> buttonArrayList= new ArrayList<Button>();
// loop to handle each button
for (int i = 0; i < buttonArrayList.size(); i++) {
Button button = buttonArrayList.get(i);
// do your stuff with each button
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
}

Show/Hide top bar like chrome, but with some static content and a listview

First let me give a short introduction and then show you what end goal looks:
So far I've added a scrolllistener to my listactivity, so that I can detect scrolling, though it does not give me any animation on android:animateLayoutChanges="true". So when i change the margin's of the view programmatically, it just does these changes instantly, and not that well, any help is most welcomed.
As you can see in my xml, i place the item I'm going to hide slowly first so other will be above it on the Z-axis.

how to inflate a list view to a fragment

i am using fragment in my application.there are 5 tabs.in 1 tab i need to inflate a list view on a button click.given below is my code for that tab.
