Custom View getHitRect return wrong value

I created a new custom view that looks like this
public class SearchCategoryPanel extends RelativeLayout {
private boolean hasRetrieved = false;
private GridLayout categoryContainer;
private TextView scpLoadingText;
public static final int HEIGHT = 360;
private ArrayList<OnCategoryItemClickListener> onCategoryItemClickListeners = new ArrayList<OnCategoryItemClickListener>();
public SearchCategoryPanel(Context context) {
super(context);
init();
}
public SearchCategoryPanel(Context context, AttributeSet attrs) {
super(context, attrs);
Log.i(SearchCategoryPanel.class.getSimpleName(), this.getTop() + "");
init();
}
public SearchCategoryPanel(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public void init() {
inflate(getContext(), R.layout.search_category_panel, this);
this.scpLoadingText = (TextView) findViewById(R.id.sCategoryPanelLoadingText);
this.categoryContainer = (GridLayout) findViewById(R.id.sCategoryContainer);
this.setVisibility(View.GONE);
}
public void show() {
this.setVisibility(View.VISIBLE);
}
public void hide() {
this.setVisibility(View.GONE);
}
public void setProcessing(boolean on) {
if(!on) {
this.scpLoadingText.setVisibility(View.GONE);
} else {
this.scpLoadingText.setVisibility(View.VISIBLE);
}
}
public void addCategoryItemUsingVo(CategoryVo categoryVo) {
CategoryItem item = new CategoryItem(getContext());
item.setCategoryVo(categoryVo);
item.setOnItemClickListener(new CategoryItem.OnClickListener() {
#Override
public void onClick(CategoryVo categoryVo) {
triggerOnCategoryItemClickListener(categoryVo);
}
});
this.categoryContainer.addView(item);
}
public void removeAllItems() {
this.categoryContainer.removeAllViews();
}
public boolean hasRetrieved() {
return hasRetrieved;
}
public interface OnCategoryItemClickListener {
public void onClick(CategoryVo categoryVo);
}
public void setOnCategoryItemClickListener(OnCategoryItemClickListener listener) {
this.onCategoryItemClickListeners.add(listener);
}
private void triggerOnCategoryItemClickListener(CategoryVo vo) {
for(OnCategoryItemClickListener listener : onCategoryItemClickListeners ) {
listener.onClick(vo);
}
}
}
Then, I try to call the getHitRect
Rect rectF = new Rect();
searchCategoryPanel.getHitRect(rectF);
Log.i(ARModeActivity.class.getSimpleName(), "Rect: " + rectF.toString());
The log returns strange value: Rect: Rect(0, 0 - 1920, 1164). this means the relative layout covers the whole screen which is not correct.
The SearchCategoryPanel xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#7F000000"
android:layout_alignParentBottom="true"
android:maxHeight="360dp"
android:layout_height="160dp">
<LinearLayout
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Search Category"
android:textAlignment="center"
android:textColor="#android:color/white"
android:textSize="24dp"/>
<TextView
android:id="#+id/sCategoryPanelLoadingText"
android:layout_width="wrap_content"
android:textSize="24sp"
android:textColor="#android:color/white"
android:layout_height="match_parent"
android:text="Loading.."/>
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<GridLayout
android:id="#+id/sCategoryContainer"
android:layout_width="wrap_content"
android:orientation="horizontal"
android:layout_height="wrap_content">
</GridLayout>
</HorizontalScrollView>
</LinearLayout>
</RelativeLayout>
The relative layout only has 360dp in height, andfull width (look at the xml). but it returns the wrong value. I have read about onMeasure and onSizeChanged, but nothing helped
Here How I call the search_category_panel layout:
<?xml version="1.0" encoding="utf-8"?>

My first approach would be not to override the onMeasure() in your custom view SearchCategoryPanel. Because you are forcing a different dimension than the ones provided by the xml.

Button overriding listview items and how to add textview just above listview

I have a listview between header and button, I want to add textview just above listview and button to align properly so that button do not override listview items. How can i do that? Not sure what is the issue with xml layout

Have you considered adding a headerview to listview. You could actually use a layout as header for listview. This way, you views on header will never overflow on to listview.
final ListView lstVRHDetails = (ListView) getActivity().findViewById(R.id.listview);
LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View headerView = inflater.inflate(<header layout>, new LinearLayout(getActivity()), false);
headerView.findViewById(R.id.rlFromDate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});
headerView.findViewById(R.id.rlToDate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
}
});
headerView.findViewById(R.id.imgUpdate).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
}
});
headerView.setLayoutParams(new ListView.LayoutParams(ListView.LayoutParams.MATCH_PARENT, ListView.LayoutParams.WRAP_CONTENT));
lstVRHDetails.addHeaderView(headerView);

Custom Alignment of RadioButtons in Android

I have 4 RadioButtons (part of same RadioGroup) and I want to align them like this :
Code I am using is :
<RadioGroup
android:id="#+id/add_reminder_type"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="#dimen/zero"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_daily"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_daily" />
<RadioButton
android:id="#+id/add_reminder_weekly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_weekly" />
</LinearLayout>
<LinearLayout
android:layout_width="#dimen/zero"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_monthly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_monthly" />
<RadioButton
android:id="#+id/add_reminder_yearly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/add_reminder_yearly" />
</LinearLayout>
</RadioGroup>
But by using this code, RadioGroup loses its property and all the RadioButtons can be checked at same time.
Any idea how RadioGroup can retain its property using this type of alignment ?

You can Try This....
first declare all radio button
r1=(RadioButton) findViewById(R.id.add_reminder_daily);
r2=(RadioButton) findViewById(R.id.add_reminder_weekly);
r3=(RadioButton) findViewById(R.id.add_reminder_monthly);
r4=(RadioButton) findViewById(R.id.add_reminder_yearly);
now on - onclick listner do
r1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r2.setChecked(false);
r3.setChecked(false);
r4.setChecked(false);
}
});
r2.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r1.setChecked(false);
r3.setChecked(false);
r4.setChecked(false);
}
});
r3.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r2.setChecked(false);
r1.setChecked(false);
r4.setChecked(false);
}
});
r4.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
r2.setChecked(false);
r3.setChecked(false);
r1.setChecked(false);
}
});

try below code works fine at my end:-
<RadioGroup
android:id="#+id/add_reminder_type"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_marginLeft="10dp"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_daily"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Daily" />
<RadioButton
android:id="#+id/add_reminder_weekly"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Monthly" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_monthly"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Weekly" />
<RadioButton
android:id="#+id/add_reminder_yearly"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Yearly" />
</LinearLayout>
</RadioGroup>

use this code :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<RadioGroup
android:id="#+id/add_reminder_type"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="#dimen/zero"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_daily"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:checked="true"
android:text="daily" />
<RadioButton
android:id="#+id/add_reminder_weekly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="weekly" />
</LinearLayout>
<LinearLayout
android:layout_width="#dimen/zero"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center_horizontal"
android:orientation="vertical" >
<RadioButton
android:id="#+id/add_reminder_monthly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="monthly" />
<RadioButton
android:id="#+id/add_reminder_yearly"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="yearly" />
</LinearLayout>
</RadioGroup>
</LinearLayout>

In the adapter i dont have any strangle, but if you need i copy it here..I try with fill_parent wrap_content etc but nothing works..
Edit: the adapter code:
public class GridAdapter extends BaseAdapter {
private LayoutInflater inflater;

Edit2:
I did more simply the XML, but the rows dont show.

Here is some simplified example to achieve needed layout

android:layout_height="wrap_content"
android:src="#drawable/ic_icon" />
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout

How to populate the same view with layout inflater?

I have a layout and every time my button is pressed I want to add a group of views stored in another layout. This is the way I tried it so far. The error in logcat is:
"E/AndroidRuntime(7900): java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first."
Code:
material_cost.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/materialCostText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Κόστος Υλικών"
android:textColor="#FF0000"
android:textSize="16sp"
android:textStyle="bold"
android:gravity="center_horizontal"
android:layout_margin="5dp"/>
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5E5" />
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/materialWrapper">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp">
<Button
android:id="#+id/btnMaterialSubmit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Αποθήκευση"
android:layout_weight="50"/>
<Button
android:id="#+id/btnMaterialAdd"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Προσθήκη πεδίου"
android:layout_weight="50"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
material_cost_item.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/materialItem"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Υλικό"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Τιμή μονάδας"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"
/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<TextView
android:layout_width="50dp"
android:layout_height="wrap_content"
android:id="#+id/materialText"
android:text="Ποσότητα"
android:textSize="16sp"
android:textStyle="italic"
android:layout_weight="50"
android:layout_marginLeft="5dp"/>
<EditText
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_weight="50"

</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<View
android:layout_width="match_parent"
android:layout_height="2dp"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
android:background="#33B5D8" />
</LinearLayout>
</LinearLayout>
And finally my class:
public class MaterialActivity extends Activity implements OnClickListener {
Button btnAdd;
LinearLayout rootLayout;
View layoutItem;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.material_cost);
btnAdd = (Button) findViewById(R.id.btnMaterialAdd);
rootLayout = (LinearLayout) findViewById(R.id.materialWrapper);
layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, rootLayout,false);
rootLayout.addView(layoutItem);
btnAdd.setOnClickListener(this);
}
public void onClick(View v){
switch (v.getId()){
case R.id.btnMaterialAdd:{
inflateEntry();
break;
}
}
}
private void inflateEntry() {
// TODO Auto-generated method stub
Log.v("debug","pressed");
rootLayout.addView(layoutItem);
}
}

you need to inflate the view again every time you click the button:
private void inflateEntry()
{
// TODO Auto-generated method stub
Log.v("debug","pressed");
View layoutItem = getLayoutInflater().inflate(R.layout.material_cost_item, null);
rootLayout.addView(layoutItem);
}
