What's wrong with this dynamic layout? [Android]

What's wrong with this dynamic layout? [Android] - android

I need to create dynamically LinearLayout which represent this xml code:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ddd"
android:orientation="vertical"
android:padding="1dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff"
android:orientation="horizontal"
android:paddingBottom="26dp"
android:paddingTop="26dp" >
<LinearLayout
android:layout_width="160dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#fff" >
<ImageView
android:id="#+id/ImageView04"
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_gravity="top"
android:layout_marginLeft="32dp"
android:layout_marginTop="4dp"
android:background="#eee" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#fff"
android:orientation="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:gravity="top"
android:paddingBottom="4dp"
android:paddingLeft="16dp"
android:text="Name of event"
android:textSize="22sp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="16dp"
android:text="Group of this event"
android:textColor="#aaa"
android:textSize="16sp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
But the problem is that I wrote some code but I have no idea why after debugging my application the only thing which I see is name of event.
Here's the code:
public class Event extends LinearLayout{
private LinearLayout globalContener;
private LinearLayout contener;
private LinearLayout avatarBox;
private LinearLayout contentBox;
private TextView eventName;
private TextView eventGroup;
private ImageView avatar;
private LinearLayout.LayoutParams globalContenerParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
private LinearLayout.LayoutParams contenerParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
private LinearLayout.LayoutParams avatarBoxParams = new LinearLayout.LayoutParams(160, LayoutParams.MATCH_PARENT, 1.0f);
private LinearLayout.LayoutParams contentBoxParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
private LinearLayout.LayoutParams eventNameParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
private LinearLayout.LayoutParams eventGroupParams = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
private LinearLayout.LayoutParams avatarParams = new LinearLayout.LayoutParams(48, 48);
public Event(Context context){
super(context);
// Design of global contener
globalContenerParams.setMargins(0, 0, 0, 32);
globalContener = new LinearLayout(context);
globalContener.setBackgroundColor(0xDDDDDD);
globalContener.setPadding(1, 1, 1, 1);
globalContener.setOrientation(LinearLayout.VERTICAL);
globalContener.setLayoutParams(globalContenerParams);
// Design of contener
contener = new LinearLayout(context);
contener.setBackgroundColor(0xFFFFFF);
contener.setPadding(0, 26, 0, 26);
contener.setOrientation(LinearLayout.HORIZONTAL);
contener.setLayoutParams(contenerParams);
// Design of avatar box
avatarBox = new LinearLayout(context);
avatarBox.setBackgroundColor(0xFFFFFF);
avatarBox.setLayoutParams(avatarBoxParams);
// Design of contet box
contentBox = new LinearLayout(context);
contentBox.setOrientation(LinearLayout.VERTICAL);
contentBox.setBackgroundColor(0xFFFFFF);
contentBox.setLayoutParams(contentBoxParams);
// Design of avatar
avatarParams.gravity = Gravity.TOP;
avatarParams.setMargins(32, 4, 0, 0);
avatar = new ImageView(context);
avatar.setBackgroundDrawable(Const.avatarImg);
avatar.setLayoutParams(avatarParams);
// Design of event name
eventNameParams.gravity = Gravity.TOP;
eventName = new TextView(context);
eventName.setGravity(Gravity.TOP);
eventName.setPadding(16, 0, 0, 4);
eventName.setTextSize(22);
eventName.setText("Sprawdzian z języka polskiego");
eventName.setLayoutParams(eventNameParams);
// Design of event group
eventGroup = new TextView(context);
eventGroup.setGravity(Gravity.CENTER);
eventGroup.setPadding(16, 0, 0, 0);
eventGroup.setTextSize(16);
eventGroup.setTextColor(0xAAAAAA);
eventGroup.setText("4ia Technikum Łączności w Krakowie");
eventGroup.setLayoutParams(eventGroupParams);
// Packing boxes
avatarBox.addView(avatar);
contentBox.addView(eventGroup);
contentBox.addView(eventName);
contener.addView(avatarBox);
contener.addView(contentBox);
globalContener.addView(contener);
// Adding to view
addView(globalContener);
}
}
Is anyone here who can help me with this?

set your main LinearLayout Orientation to Vertical
and then
set contentBoxParams weight to 1f
private LinearLayout.LayoutParams contentBoxParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT,1.0f);
then
put this
contentBox.addView(eventName);
before this
contentBox.addView(eventGroup);
and then replace all the
0xFFFFFF with 0xFFFFFFFF

Setting stacked up layout programmatically in android

I would like to have a relative layout with linear layouts nested in between them but i am unable to understand how ill nest them programmatically
This is what i have as my xml file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:text="Add items" />
<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/button_top"
android:gravity="center_horizontal"
android:orientation="horizontal"
android:weightSum="1">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:orientation="vertical"
android:padding="2dp">
<TextView

</LinearLayout>
</LinearLayout>
This produces the layout that i want:
Now i would like to add the above layout and change it to a java way
I hav tried
//top layout
RelativeLayout newlayout = new RelativeLayout(getContext());
LinearLayout belowlayout = new LinearLayout(getContext());
LinearLayout above_part = new LinearLayout(getContext()); //lin with id of above_part
LinearLayout in_above_part_one = new LinearLayout(getContext()); //lin with id of above_part
//layouts properties
belowlayout.setOrientation(LinearLayout.HORIZONTAL);
//setids for the layouts
newlayout.setId(12);
belowlayout.setId(13);
//Button
Button additemsbtn = new Button(getContext());
additemsbtn.setText("Log In");
additemsbtn.setBackgroundColor(Color.BLACK);
//Username input
EditText username = new EditText(getContext());
additemsbtn.setId(int 1);
username.setId(2);
RelativeLayout.LayoutParams buttonDetails = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT,
);
RelativeLayout.LayoutParams usernameDetails = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT
);
//Give rules to position widgets
usernameDetails.addRule(RelativeLayout.ABOVE, additemsbtn.getId());
usernameDetails.addRule(RelativeLayout.CENTER_HORIZONTAL);
usernameDetails.setMargins(0,0,0,50);
buttonDetails.addRule(RelativeLayout.CENTER_HORIZONTAL);
buttonDetails.addRule(RelativeLayout.CENTER_VERTICAL);
Whatever i have started fails since am unable to know how to nest the different linear layouts,
I would probably like guidelines on how to do this nesting programmatically so that i can achieve the same thing generated by the xml file

Little example how it can be done. So, all you need to do is to add inner items to my nested layouts and configure margins/paddings etc. Also added background for better visualization.
RelativeLayout root = (RelativeLayout) findViewById(R.id.root);
Button addButton = new Button(this);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
params.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
addButton.setLayoutParams(params);
addButton.setId(123);
root.addView(addButton);
LinearLayout rootLinearlayout = new LinearLayout(this);
RelativeLayout.LayoutParams linearRootParams = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
linearRootParams.addRule(RelativeLayout.BELOW, 123);
rootLinearlayout.setBackgroundColor(ContextCompat.getColor(this, R.color.colorAccent));
rootLinearlayout.setLayoutParams(linearRootParams);
// Nested Linears
LinearLayout linearOne = new LinearLayout(this);
LinearLayout linearTwo = new LinearLayout(this);
LinearLayout linearThree = new LinearLayout(this);
LinearLayout.LayoutParams linearParamsWithWeight = new LinearLayout.LayoutParams(
0,
300);
linearParamsWithWeight.weight = 1;
linearOne.setBackgroundColor(ContextCompat.getColor(this, android.R.color.black));
linearTwo.setBackgroundColor(ContextCompat.getColor(this, android.R.color.holo_red_dark));
linearThree.setBackgroundColor(ContextCompat.getColor(this, android.R.color.holo_blue_dark));
linearOne.setLayoutParams(linearParamsWithWeight);
linearTwo.setLayoutParams(linearParamsWithWeight);
linearThree.setLayoutParams(linearParamsWithWeight);
rootLinearlayout.addView(linearOne);
rootLinearlayout.addView(linearTwo);
rootLinearlayout.addView(linearThree);

Button disappears

I have next Layout (TOP: Two Spinner Half: TableLayout Down: Button) , I have filled the TableLayout with WebService with...
"for (int i = 0; i < ljsonArray.length(); i++)"
But when the last record of WebService show in the TableLayout, the button disappeared, what's wrong?
Regards
//Click botton
public void consultar(View v){
// Building Parameters to call WebService
List<NameValuePair> params = new ArrayList<NameValuePair>();
String url = "http://futcho7.com.mx/MiScore/WebService/gettablapos.php";
params.add(new BasicNameValuePair("id_cliente", numCte.get(0)));
params.add(new BasicNameValuePair("id_sucursal", numSuc.get(0)));
params.add(new BasicNameValuePair("id_torneo", Integer.toString(idTorneo)));
params.add(new BasicNameValuePair("id_jornada", Integer.toString(idJornada)));
new AsyncConector(this, url, params, this).execute();
}

Your button is actually on the right of your tableLayout.
Change the orientation of the linearlayout to Vertical instead of horizontal.
Moreover the buttonView should be part of the scrollview if you want to see it at the end of the scrollview.
You can also nested all your xml in a Relative layout et add the attribute "android:layout_alignParentBottom="true" to the button and the button will always be visible.
Hope this helps.

It works for me when I add rows directly in xml.

Defining ImageView to be aligned right

Tried to align imageview to right.. code crashes. why?
UPDATED: Here is all row im having problem with. I think i failed on determining layouts somewhere here
TableRow tableRow1 = new TableRow(this);
tableRow1.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
tl.addView(tableRow1);
/* textView1 */
TextView textView1 = new TextView(this);
textView1.setLayoutParams(new TableRow.LayoutParams(
LayoutParam
s.MATCH_PARENT, LayoutParams.MATCH_PARENT));
textView1.setText(names);
tableRow1.addView(textView1);
ImageView icon;
icon = new ImageView(this);
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
icon.setLayoutParams(params);
// icon.setLayoutParams(params);
icon.setImageResource(R.drawable.ic_done); //default value
switch (value) {
case "1":
icon.setImageResource(R.drawable.ic_done);
break;
case "0":
icon.setImageResource(R.drawable.ic_bad);
default:
break;
}
System.out.println("value : " + value);
icon.setPadding(densityToPixels(13), 0, 0, 0);
tableRow1.addView(icon);

</LinearLayout>

First you defined the ImageView dynamically like
ImageView icon = new ImageView(this);
then you are trying to get the LayoutParam through icon.getLayoutParams(); which doesn't have any LayoutPram because you haven't set any.
To make it work replace
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)icon.getLayoutParams();
with
TableRow.LayoutParams params = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.WRAP_CONTENT);
icon.setLayoutParams(params);

How to fill the LinearLayout row?

I using LinearLayout as a table that need to contain 3 column.
I need to feel up the row an i don't know how to do it from the code in run time.
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:paddingTop="4dip"
android:paddingBottom="6dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView android:id="#+id/Cell1"
android:layout_width="50dip"
android:layout_height="wrap_content"/>
<TextView android:id="#+id/Cell2"
android:layout_width="70dip"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<TextView android:id="#+id/Cell3"
android:layout_width="60dip"
android:layout_height="wrap_content"
android:layout_weight="1"/>
</LinearLayout>

This is the code that produces layout equivalent to what you have declared in your .xml
You could put it somewhere in your activity (so this refers to your activity)
LinearLayout row = new LinearLayout(this);
row.setLayoutParams(new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
row.setPadding(0, 4, 0, 6);
row.setOrientation(LinearLayout.HORIZONTAL);
// creating and setting the cells now
// cell 1
TextView cell1 = new TextView(this);
// convert dip into pixels for LayoutParams constructor
// as it only understands px
int widthPix1 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
50, getResources().getDisplayMetrics());
row.addView(cell1, new LinearLayout.LayoutParams(
widthPix1, LinearLayout.LayoutParams.WRAP_CONTENT));
// cell 2
TextView cell2 = new TextView(this);
int widthPix2 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
70, getResources().getDisplayMetrics());
row.addView(cell2, new LinearLayout.LayoutParams(
widthPix2, LinearLayout.LayoutParams.WRAP_CONTENT, 1));
// cell 3
TextView cell3 = new TextView(this);
int widthPix3 = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
60, getResources().getDisplayMetrics());
row.addView(cell3, new LinearLayout.LayoutParams(
widthPix3, LinearLayout.LayoutParams.WRAP_CONTENT, 1));
As you can see the amount of code is significantly bigger than when your layout is in .xml and you simply inflate with
LinearLayout row = (LinearLayout) inflater.inflate(R.layout.row, null);
And I can hardly imagine a situation when you want to do it the way you asked for.
Anyways, enjoy.

My advice if I got you right:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:paddingTop="4dip"
android:paddingBottom="6dip"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView android:id="#+id/Cell1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"/>
<TextView android:id="#+id/Cell2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="7"/>
<TextView android:id="#+id/Cell3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="6"/>
</LinearLayout>

Kinda circular dependency in RelativeLayout with embedded ScrollView

Basically, an Activity should display on screen:
1. A logo on top. Must always be displayed. Must center both vertically and horizontally, when choices leaves extra space on screen.
2. A ScrollView at bottom. Hosts vertical LinearLayout, which in turn hosts a set of choices a user can choose from. Must take minimal space necessary to display all choices (So logo is vertically centered). Can take up up to (Screen - Logo) space on screen. Choices are added programmatically.
Now, I have defined it in layout as:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:padding="5dp"
android:src="#drawable/logo" />
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_below="#id/imageView"
>
<LinearLayout
android:id="#+id/ChoicesPanel"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</RelativeLayout>
If ImageView is layed out using layout_above=scrollView, ScrollView is layed out before, NOT taking into consideration minimum size of ImageView.
If ScrollView is layed out using layout_below=ImageView, ImageView just stays on top. When there are only 2-3 choices, screen looks pretty ugly.
Is there a way I can satisfy the constraints? Or should I define two different layout xml files, and switch to the correct one programmatically?

<?xml version="1.0" encoding="utf-8"?>

this seems to work for me. its like 14 items in the scrollview
