Align custom view in relative layout dynamically not working android

Align custom view in relative layout dynamically not working android - android

I have a created a custom view , in relative layout .
I'm able to align it in in center/left/right through xml but not
programatically
.
Custom View
public class HotspotView extends RelativeLayout {
public HotspotView(Context context) {
super(context);
init(context);
}
public HotspotView(Context context, AttributeSet attrs) {
super(context, attrs);
init(context);
}
public HotspotView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init(context);
}
private void init(Context context) {
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.hotspot_view, this);
}
}

Code:
RelativeLayout.LayoutParams lp = new
RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.MATCH_PARENT,
RelativeLayout.LayoutParams.MATCH_PARENT);
lp.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
ImageFrameActivity.hotspotView.setLayoutParams(lp);
ImageFrameActivity.hotspotView.setVisibility(View.VISIBLE);
I have gone through various similar questions but I'm not able to resolve the problem.

try this :
RelativeLayout.LayoutParams lp =
(RelativeLayout.LayoutParams) ImageFrameActivity.hotspotView.getLayoutParams();
lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
ImageFrameActivity.hotspotView.setLayoutParams(lp);

Try using
lp.gravity = Gravity.LEFT;

and here is SquareRelativeLayout.class
public class SquareRelativeLayout extends RelativeLayout {
public SquareRelativeLayout(Context context) {
super(context);
}
public SquareRelativeLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public SquareRelativeLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
setMeasuredDimension(widthMeasureSpec,widthMeasureSpec);
}
}
the problem is I'm not able to align APPLY button to the bottom of the SquareRelativeLayout. If I do, it becomes invisible.

Android ScrollView doesnt show top content

Im having problem where the android scrollview starts hiding a pair of textviews (Top ~5-6 lines doesnt show). I use padding, margin, fillviewport, wrap in linearlayout, original scrollview etc. many variations but it didnt work. I check this problem both api 16 and 23.
Im working many hours but doesnt find solution.

how can switch's custom right textview be center aligned?

This is my layout file:
<?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="56dp"
android:gravity="center_vertical">
<TextView
android:id="#+id/form_widget_switch_text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toEndOf="#+id/form_widget_switch"
android:gravity="center"
android:text="text" />
<com.example.daffodil.formvalidation.widgets.typefaced.SwitchButtonTF
android:id="#+id/form_widget_switch"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center"
android:switchMinWidth="40dp"
android:textOff=""
android:textOn=""
android:thumbTextPadding="5dp" />
</RelativeLayout>
This is the output I'm getting:
Problem : I want text to be center vertically aligned but as you can see its top edge is aligned with top edge of the switch.
Edit: based on comments
Why am I using TextView : I want text view to move dynamically left or right side of the switch.so I use both TextView and Switch and changing their params dynamically to move text left or right.
I want output similar to setting Switch's button text attribute.
SwitchButtonTF class which presently I'm using:
/**
* Switch with typeface attribute added.
*/
public class SwitchButtonTF extends Switch {
/**
* {#inheritDoc}
*/
public SwitchButtonTF(Context context) {
super(context);
init(context, null);
}
/**
* Initialise view.
*
* #param context context
* #param attrs layout attributes
*/
private void init(Context context, AttributeSet attrs) {
if (!isInEditMode()) {
Fonts.getInstance(context).applyTypeFace(this, context, attrs);
}
}
/**
* {#inheritDoc}
*/
public SwitchButtonTF(Context context, AttributeSet attrs) {
super(context, attrs);
init(context, attrs);
}
/**
* {#inheritDoc}
*/
public SwitchButtonTF(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init(context, attrs);
}
}
Any help?

Just add android:layout_centerVertical="true" in your textview as it is inside the relativelayout.Also set the height of the textview to wrap_content.
So your textview xml should be
<TextView
android:id="#+id/form_widget_switch_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toEndOf="#+id/form_widget_switch"
android:gravity="center"
android:layout_centerVertical="true"
android:text="text" />

Try this:
<?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="wrap_content">
<TextView
android:id="#+id/form_widget_switch_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toEndOf="#+id/form_widget_switch"
android:layout_centerVertical="true"
android:gravity="center"
android:text="text" />
<com.example.daffodil.formvalidation.widgets.typefaced.SwitchButtonTF
android:id="#+id/form_widget_switch"
android:layout_width="wrap_content"
android:layout_height="56dp"
android:gravity="center"
android:switchMinWidth="40dp"
android:textOff=""
android:textOn=""
android:thumbTextPadding="5dp" />
</RelativeLayout>

If you don't have any problem using LinearLayout in place of RelativeLayout then can you try this?
<?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="56dp"
android:orientation="horizontal">
<com.example.daffodil.formvalidation.widgets.typefaced.SwitchButtonTF
android:id="#+id/form_widget_switch"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center"
android:switchMinWidth="40dp"
android:textOff=""
android:textOn=""
android:thumbTextPadding="5dp" />
<TextView
android:id="#+id/form_widget_switch_text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center|center_vertical"
android:text="text" />
</LinearLayout>
Edit - try this with RelativeLayout
<?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="56dp"
android:gravity="center_vertical">
<TextView
android:id="#+id/form_widget_switch_text"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_toRightOf="#+id/form_widget_switch"
android:gravity="center"
android:text="text" />
<com.example.daffodil.formvalidation.widgets.typefaced.SwitchButtonTF
android:id="#+id/form_widget_switch"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center"
android:switchMinWidth="40dp"
android:textOff=""
android:textOn=""
android:thumbTextPadding="5dp" />
</RelativeLayout>

findViewById returns null - why?

I have created a custom view Game4 that extends LinearLayout. When I tried finding them, it field and returned null (and then nullPointerException and then crash/!!)
This is activity_play_game.xml:
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"

<LinearLayout

android:layout_width="match_parent"
android:layout_height="wrap_content"

<Spinner
android:id="#+id/spinner1"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
This is my OnCreate function:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_play_game);
tempGame = (Game_4) findViewById(R.id.game4); // ?? Why null ??
This is Game_4 constructors:
public class Game_4 extends LinearLayout {
public Game_4(Context context, AttributeSet attrs) {
this(context);
}
public Game_4(Context context) {
super(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.game_4_layout, this, true);
this.setWillNotDraw(false);
}

public Game_4(Context context, AttributeSet attrs) {
this(context);
}
You need to pass the attrs to the super constructor, e.g.
super(context, attrs);
Otherwise the attributes consumed by the superclass such as android:id are lost.
You can do your custom init in this two-arg constructor and call it from the 1-arg constructor as well:
public Game_4(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.game_4_layout, this, true);
this.setWillNotDraw(false);
}
public Game_4(Context context) {
this(context, null);
}

Game_4 has not been imported properly. Also in layout , press CTRL and take the cursor to com.example.sortthegraph.Game_4 and click to go to the corresponding class. If it does not direct to that corresponding class, then there may be some issue.

GridView Expandable Height

I'm using ExpandableHeightGridView but I don't manage to calculate the correct height of the gridview, I use custom rows made by an external layout, but it cuts several rows at the bottom,
here's the code:
public class ExpandableHeightGridView extends GridView {
boolean expanded = false;
public ExpandableHeightGridView(Context context) {
super(context);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public ExpandableHeightGridView(Context context, AttributeSet attrs,
int defStyle) {
super(context, attrs, defStyle);
}
public boolean isExpanded() {
return expanded;
}
#Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (isExpanded()) {
int expandSpec = MeasureSpec.makeMeasureSpec(MEASURED_SIZE_MASK,
MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, expandSpec);
ViewGroup.LayoutParams params = getLayoutParams();
params.height = getMeasuredHeight();
} else {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
}
public void setExpanded(boolean expanded) {
this.expanded = expanded;
}
