Cannot add childs to linearLayout - android

In my app what i want is to dynamically add buttons to a linear layout based on the length of the array.For example if the length of array is 4 then ,4 buttons should be added to the linear layout.I tried doing that but always my app crashes
The linearlayout which is at the bottom of the xml is where i wanna add the buttons

The layout where i want to create buttons dynamically

Code
if (NewDataSet.get("Table2") instanceof JSONArray) {

numOfDocCircles = array.length();
LayoutInflater layoutInflater;
Button button = new Button(context);

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
}
});
}

EDIT: I know what is a NullPointerException, I already checked the previous posts on the subject, but no problem is the same as mine

I think the problem is with findViewByID. The documentation says
findViewById
Added in API level 1
View findViewById (int id)
Finds a child view with the given identifier. Returns null if the specified child view does not exist or the dialog has not yet been fully created (for example, via show() or create()).
It is just possible that since you are calling show() later the textView might not be created. I would do this
View dialogView = LayoutInflater.from(context).inflate(R.layout.dialog_filtro, null);
Button bt_cancelar = (Button) dialogView.findViewById(R.id.cb_filtro_cancelar);
Button bt_aceitar = (Button) dialogView.findViewById(R.id.cb_filtro_aceitar);
seek_preco = (SeekBar) dialogView.findViewById(R.id.sb_preco_max);
tv_filtro = (TextView) dialogView.findViewById(R.id.tv_filtro_preco);
spinner_categoria = (Spinner) dialogView.findViewById(R.id.spinner_categoria);
spinner_vendedor = (Spinner) dialogView.findViewById(R.id.spinner_vendedor);
dialog.setContentView(dialogView)
dialog.show();
spinner_categoria.setAdapter(ArrayAdapter.createFromResource(
this, R.array.categoria_array, android.R.layout.simple_spinner_item));
spinner_vendedor.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item,listVendedor));
tv_filtro.setText("oi");

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.
