Android radiogroup with nested linearlayouts not deselecting radiobuttons [duplicate] - android

This question already has answers here:
How to group RadioButton from different LinearLayouts?
(21 answers)
Closed 5 years ago.
I have a group of radiobuttons in a radiogroup that refuses to behave the way I'd like. The radiobuttons need to be two lines of two, and one line of one, with the last button having an edittext instead of a label. The layout looks correct, but the radiobuttons allow more than one to be selected and won't deselect any.
Below is my XML:
<RadioGroup
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rgDesignation">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/llVT1">
<RadioButton
android:text="#string/pressure_equipment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbPE"
android:layout_weight="1" />
<RadioButton
android:text="#string/assemblies"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbAss"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/llVT2">
<RadioButton
android:text="#string/unheated"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbUnh"
android:layout_weight="1" />
<RadioButton
android:text="#string/heated"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/rbH"
android:layout_weight="1" />
</LinearLayout>
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:id="#+id/llVT3">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/rbOwnSel"
android:layout_weight="0" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:inputType="text"
android:ems="10"
android:id="#+id/etOwnChoice"
android:layout_weight="1"
android:textColor="#android:color/black"
android:background="#android:color/white"
android:elevation="5dp" />
</LinearLayout>
</RadioGroup>

Make custom RadioGroup class like this:

First image appearing small in size and on top left corner in a viewpager when rotate the device

Hi in my application i am using the Viewpager with PagerAdapter. it contains n number of images. but when i rotate the device when viewpager is on first image then the image shift to top left corner and appears very small. please have a look in the attached image.
code which i am using
public class CustomViewPager extends ViewPager {
private final long SWITCH_TIME_INTERVAL = 5000;

child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if (h > height)
height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}

adapter.notifyDataSetChanged();
listView.setAdapter(adapter);
listView.setItemsCanFocus(false);

I can not delete it, because I need it in the project. I do not know how to fix this situation

Sometimes the ListView click doesn't work. And at this case you might have to add one more attribute.
android:descendantFocusability="blocksDescendants"
Add this attribute to the top most layout of your XML where you have provided the ListView elements.

In your ListView remove the xml attribute android:clickable="true"
This is taking your click event and not sending it down to the child views.
Edit
You are passing in getApplicationContext() which is the wrong context. The listener does work, but the Toast is not displaying in the right context. You need to pass in getContext(). However, since this is an Activity, you can just pass in this instead.
public void outputListView(ArrayList<String> list) {
Adapter adapter = new Adapter(this, R.layout.item, list);
adapter.notifyDataSetChanged();
listView.setAdapter(adapter);
listView.setItemsCanFocus(false);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
Toast.makeText(this, String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});
}

ListView cannot scroll

I have tried to scroll the ListView up when the event item is more than the space of the ListView but it fails. I would like to know if I can make the ListView scrollable without adding any listener. Thank you.

If you don't want to use any listener then you can simply use a custom ListView like this,
public class CustomListView extends ListView implements View.OnTouchListener, AbsListView.OnScrollListener {
private static final int MAXIMUM_LIST_ITEMS_VIEWABLE = 99;
private int listViewTouchAction;
public CustomListView (Context context, AttributeSet attrs) {
super(context, attrs);
listViewTouchAction = -1;
setOnScrollListener(this);
setOnTouchListener(this);
}
#Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
scrollBy(0, -1);
}
}
}
#Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int newHeight = 0;
final int heightMode = MeasureSpec.getMode(heightMeasureSpec);
int heightSize = MeasureSpec.getSize(heightMeasureSpec);
if (heightMode != MeasureSpec.EXACTLY) {
ListAdapter listAdapter = getAdapter();
if (listAdapter != null && !listAdapter.isEmpty()) {
int listPosition = 0;
for (listPosition = 0; listPosition < listAdapter.getCount()
&& listPosition < MAXIMUM_LIST_ITEMS_VIEWABLE; listPosition++) {
View listItem = listAdapter.getView(listPosition, null, this);
//now it will not throw a NPE if listItem is a ViewGroup instance
if (listItem instanceof ViewGroup) {
listItem.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
}
listItem.measure(widthMeasureSpec, heightMeasureSpec);
newHeight += listItem.getMeasuredHeight();
}
newHeight += getDividerHeight() * listPosition;
}
if ((heightMode == MeasureSpec.AT_MOST) && (newHeight > heightSize)) {
if (newHeight > heightSize) {
newHeight = heightSize;
}
}
} else {
newHeight = getMeasuredHeight();
}
setMeasuredDimension(getMeasuredWidth(), newHeight);
}
#Override
public boolean onTouch(View v, MotionEvent event) {
if (getAdapter() != null && getAdapter().getCount() > MAXIMUM_LIST_ITEMS_VIEWABLE) {
if (listViewTouchAction == MotionEvent.ACTION_MOVE) {
scrollBy(0, 1);
}
}
return false;
}
}
Then use in your layout,
<CustomListView
android:id="#+id/event_list"
android:scrollbars="vertical"
android:fastScrollEnabled="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:layout_marginRight="20dp"
android:layout_below="#id/titleBar"
android:layout_above="#+id/DelAll" />

I Have made it as a widget and Now finally to add this to your List View use
frame = (QuickReturnRelativeLayoutFooter) newProjectsView
.findViewById(R.id.frame);
frame.attach(projectsList);
where projectList is your List View
example
ListView projectList =(ListView)findViewById(R.id.projectList);
and Voila Cheers Completed Smooth as Heaven .......

The problem is in DemoPopupWindow.onCreate method:
ViewGroup root = (ViewGroup) inflater.inflate(
R.layout.popup_grid_layout, null);
for (int i = 0, icount = root.getChildCount(); i < icount; i++) {
View v = root.getChildAt(i);
if (v instanceof TableRow) {
root will be RelativeLayout defined in popup_grid_layout.xml. Later you iterate through all its children and set onclick listeners only if child view is TableRow, which is never the case. I guess what you want there is to find horizontalScrollView1 view and do the same with its children instead, something like:
View horizontalScrollView1 = findViewById(R.id.horizontalScrollView1);
for (int i = 0, icount = horizontalScrollView1.getChildCount(); i < icount; i++) {
View v = horizontalScrollView1.getChildAt(i);
if (v instanceof TableRow) {
