Place three items of recyleview in the screen programmatically

I want to set width and height of each item programmatically (textview + recyleview) so that I can place three ones no matter which device renders it (when devices differ I got different width and height because of density metrics). My code for doing this issue is as following:
public class ItemRowHolder extends RecyclerView.ViewHolder {
protected TextView playlistTitle;
protected Button playlistMoreButton;
protected RecyclerView playlist_recycler_view_list;
public ItemRowHolder(View view) {
super(view);
this.playlistTitle = (TextView) view.findViewById(R.id.playlist_title);
this.playlist_recycler_view_list = (RecyclerView) view.findViewById(R.id.playlist_recycler_view_list);
this.playlistTitle.measure(0,0);
DisplayMetrics displayMetrics = mContext.getResources().getDisplayMetrics();
int screenHeight = (int )displayMetrics.heightPixels;
int titleHeight = this.playlistTitle.getMeasuredHeight();
int rcvHeight = this.playlist_recycler_view_list.getLayoutParams().height;
int layoutHeight = 0;
if (view.getLayoutParams() instanceof ViewGroup.MarginLayoutParams) {
ViewGroup.MarginLayoutParams p = (ViewGroup.MarginLayoutParams) view.getLayoutParams();
p.setMargins(5, 20, 5, 20);
view.requestLayout();
}
layoutHeight = (int)(screenHeight - displayMetrics.density* titleHeight-displayMetrics.density*120)/3;
Log.d("MOMOPix","ydpi: "+ displayMetrics.density);
Log.d("MOMOPix","Screen height: "+ screenHeight);
Log.d("MOMOPix","RCV height: "+ rcvHeight);
Log.d("MOMOPix","Title height: "+titleHeight);
Log.d("MOMOPix","Layout height: "+layoutHeight);
this.playlist_recycler_view_list.getLayoutParams().height= layoutHeight;
}
}
layout is as following:
<?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="wrap_content"
android:background="?android:selectableItemBackground"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/playlist_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_centerVertical="true"
android:layout_gravity="center_vertical"
android:text="Sample title"
android:textColor="#android:color/white"
android:textSize="18dp" />
</RelativeLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/playlist_recycler_view_list"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_gravity="center_vertical"
android:orientation="horizontal" />
</LinearLayout>
for some devices I get desired results and I want for all devices
Thanks in advances.

You're doing it in very weird and error prone way.
If you want to alter how items are laid out, you should override RecyclerVIew.LayoutManager (which is specifically made to lay out the views as its name suggests) instead of performing weird measurement hacks in your ViewHolder.
To have RecyclerView fit three items vertically (I assume it's LinearLayoutManager, your code sample does not mention it) we only have to override one method in LayoutManager:
recyclerView.setLayoutManager(new LinearLayoutManager(context){
#Override
public boolean checkLayoutParams(RecyclerView.LayoutParams lp) {
// force height of viewHolder to be a third of RecyclerView
// this will override layout_height from xml
lp.height = getHeight() /3;
return true;
}
});

Some layouts expanding slower than others when using LayoutTransition.CHANGING

I have 19 horizontal linearlayouts that are arranged vertically within another linearlayout. They are nearly empty and onclick show text. I am animating the layouts with
parentOne.getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING);
For some reason the first 7 layouts seem to be opening onClick a little slower than the 8th. Only by a split second but I have asked others to look at it when I open it to make sure I'm not crazy. I would post the entire file but it is HUGE and is over the maximum allowable text on this. So here is the meat and potatoes. So, why are my layouts opening slower than others? Numbers 8-19 open instantly onClick and 1-7 have a small delay that is noticeable.

Well I figured it out. It looks as though it was a processing issue. If I had to guess I would say that each time I called a method it would search through the giant list of linearlayouts in the onCreate method for the animation to open it.
In my onCreate method I define a CRAP TON of linear layouts as such
LinearLayout parentOne = (LinearLayout) findViewById(R.id.TFCLayoutOne);
parentOne.getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING);
The Fix:
I separated ALL of them and placed them all in their respective onClick methods. Now, when I click them they actually open faster than my other pages that are setup similarly, so I will be changing those as well. My java methods were:
private boolean mOpenOne = false;
public void toggleOne(View view){
TextView stepOne = (TextView)findViewById(R.id.stepOne);
ImageView toggle = (ImageView)findViewById(R.id.toggleStepOne);
if(mOpenOne){
stepOne.setText("Step 1:");
toggle.setImageResource(R.drawable.open);
}
else{
stepOne.setText("1. Casualties with an altered mental status should be disarmed immediately.");
toggle.setImageResource(R.drawable.close);
}
mOpenOne = !mOpenOne;
}
I have changed them to:
private boolean mOpenOne = false;
public void toggleOne(View view){
TextView stepOne = (TextView)findViewById(R.id.stepOne);
ImageView toggle = (ImageView)findViewById(R.id.toggleStepOne);
LinearLayout parentOne = (LinearLayout) findViewById(R.id.TFCLayoutOne);
parentOne.getLayoutTransition().enableTransitionType(LayoutTransition.CHANGING);
if(mOpenOne){
stepOne.setText("Step 1:");
toggle.setImageResource(R.drawable.open);
}
else{
stepOne.setText("1. Casualties with an altered mental status should be disarmed immediately.");
toggle.setImageResource(R.drawable.close);
}
mOpenOne = !mOpenOne;
}
Hope this helps others!

In Android get center of Relative Layout on API 10

I'm trying to find the center coordinates of a RelativeLayout that for the moment, is empty. I need to find the center before I can put anything into the Relative Layout. The Relative Layout is not the whole screen, so I can't use metrics to find the screen dimensions. Since my minimum API is 10, I can't use rLayout.getX() or rLayout.getY(). So what I've tried is:
int xScreenInt = gBoard_RL.getWidth()/2;
int yScreenInt = gBoard_RL.getHeight()/2;
int xInt = gBoard_RL.getLeft() + xScreenInt;
int yInt = gBoard_RL.getTop() + yScreenInt;
and all I get is 0,0. Does anyone have an any ideas how I can get this done? Here's my layout and the Activity so far:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/gb1_root_RL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FFFFFF"
tools:context=".GB1" >
<RelativeLayout
android:id="#+id/gb1_topInfo_RL"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#drawable/blu_grade_bg"
android:orientation="vertical"
android:paddingBottom="15dp" >
<TextView
android:id="#+id/gb1_scValue_TV"
style="#style/mainScoreValueStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/gb1_score_TV"
android:layout_marginLeft="10dp" />
<TextView
android:id="#+id/gb1_timeValue_TV"
style="#style/mainTimeValueStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/gb1_time_TV"
android:layout_marginRight="10dp" />
</RelativeLayout>
<RelativeLayout
android:id="#+id/gb1_gf_RL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/gb1_topInfo_RL"
android:padding="10dp" >
</RelativeLayout>
the Relative Layout I need to find the center of is: android:id="#+id/gb1_gf_RL"
public class GB1 extends Activity {
TextView GScore_TV;
RelativeLayout gBoard_RL;
int xScreenInt, yScreenInt, xInt, yInt;
String xStr, yStr;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
overridePendingTransition(R.anim.cutin, R.anim.cutout);
setContentView(R.layout.gb_layout);
GScore_TV = (TextView) findViewById(R.id.G1_scoreValue_TV);
gBoard_RL = (RelativeLayout) findViewById(R.id.gb1_gf_RL);
gBoard_RL.setBackgroundColor(Color.MAGENTA);
xScreenInt = gBoard_RL.getWidth()/2;
yScreenInt = gBoard_RL.getHeight()/2;
xInt = gBoard_RL.getLeft() + xScreenInt;
yInt = gBoard_RL.getTop() + yScreenInt;
xStr = String.valueOf(xInt);
yStr = String.valueOf(yInt);
GScore_TV.setText(xStr + ", " + yStr);
}
}

Try putting your code in a onGlobalLayout listener:
myRelativelayout.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
this.layout.getViewTreeObserver().removeGlobalOnLayoutListener(this);
//Your code here
}
});
EDIT:
Since, as #xorgate pointed out, the layout isnt drawn yet in the onCreate method. The onGlobalLayout method will be called when the layout is drawn and calculations such as yours should be done in there.

onCreate is called before a layout pass is done. All Views will have no size yet.
Try setting a global layout listener, and do the positioning code there.

setPadding(0,0,0,0) called several times on View after constructor

Good evening! I'm trying to setPadding on a custom View i built and the native setPadding() did nothing so i wrote my own... After a while i realized that setPadding gets called several times after my original call and i have no idea why... Please help :) (I realize that my custom setPadding maybe quite excessive ^^)
Here is the XML containing the View. It's the PieChart.
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/PieDialog_llParent"
android:layout_width="match_parent"

<TextView

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="Header"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="#+id/PieDialog_tvDiv1"
android:layout_width="match_parent"
android:layout_height="2dp"
android:textSize="0sp"/>

}
}

Just to extrapolate on my comment, it is your custom View object's responsibility to respect the padding that is set. You can do something like the following to make sure that you handle that case:
onMeasure()
int desiredWidth, desiredHeight;
desiredWidth = //Determine how much width you need
desiredWidth += getPaddingLeft() + getPaddingRight();
desiredHeight = //Determine how much height you need
desiredHeight += getPaddingTop() + getPaddingBottom();
int measuredHeight, measuredWidth;
//Check against the MeasureSpec -- if it's MeasureSpec.EXACTLY, or MeasureSpec.AT_MOST
//follow those restrictions to determine the measured dimension
setMeasuredDimension(measuredWidth, measuredHeight);
onLayout()
int leftOffset = getPaddingLeft();
int topOffset = getPaddingTop();
//layout your children (if any) according to the left and top offsets,
//rather than just 0, 0
onDraw()
canvas.translate (getPaddingLeft(), getPaddingTop());
//Now draw your stuff as normal

How to find layout_marginTop

I have an XML file with the following attritubes:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/al_cs_layout1"
android:gravity="center_vertical">
<ImageView android:id="#+id/cs_track"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/fader_background5"
android:layout_marginLeft="0dp"
android:layout_marginTop="20dp" >
</ImageView>
...
and here is my java code:
public void initialize(Context context)
{
Log.d("initialize (MySeekBar)","initialize");
setWillNotDraw(false);
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view1 = inflater.inflate(R.layout.custom_seekbar, this);
layout1 = (RelativeLayout)view1.findViewById(R.id.al_cs_layout1);
track = (ImageView)layout1.findViewById(R.id.cs_track);
thumb = (ImageView)layout1.findViewById(R.id.cs_thumb);
...
I am working on a custom seekbar which determines the top by using a variable marginTop = 20; however this was oringally made on a phone much older by a different programmer. The 20 suppose to represent the margin top defined in the XML however it is using dp and not pixels. how can I find the marginTop attribute of R.id.cs_track? It works great on the old phone but on any phone does doesn't have the same screen size of dp it will create an undesired offset.

Use MarginLayoutParams to get value in pixels:
track = (ImageView)layout1.findViewById(R.id.cs_track);
MarginLayoutParams params = (MarginLayoutParams)track.getLayoutParams();
int marginTopPixelSize = params.topMargin;
