I have five rows imageView, but this code load only 4 rows? why?
Java code
tl = (TableLayout) findViewById(R.id.tableLayout);
for (int i = 0; i < tl.getChildCount(); i++) {
View v = tl.getChildAt(i);
if (v instanceof TableRow) {
for (int j = 0; j < ((TableRow) v).getChildCount(); j++) {
View innerView = ((TableRow) v).getChildAt(j);
if (innerView instanceof ImageView) {
imageList.add((ImageView) innerView);
idList.add(innerView.getId());
}
}
}
}

I can comparing two imageView? eg
image.get(1).getdrawable()==image.get(2).getdrawable()?
No, by this way it just comparing whether they are the same object or not. In this case this will be false. But, if you want to compare the images of the imageviews, then you should get theirs bitmap then use sameAs method.
//comapre objects returns false
Log.i("EQ", (imageList.get(0).getDrawable().equals(imageList.get(1).getDrawable())) + "");
Log.i("EQ", imageList.get(0).getDrawable().toString()); //android.graphics.drawable.BitmapDrawable#89c323c
Log.i("EQ", imageList.get(1).getDrawable().toString()); //android.graphics.drawable.BitmapDrawable#837dbc5
BitmapDrawable bitmapDrawable0 = ((BitmapDrawable) imageList.get(0).getDrawable());
Bitmap bitmap0 = bitmapDrawable0 .getBitmap();
BitmapDrawable bitmapDrawable1 = ((BitmapDrawable) imageList.get(1).getDrawable());
Bitmap bitmap1 = bitmapDrawable1 .getBitmap();
//comapre the image returns true
Log.i("EQ2", Boolean.toString(bitmap0.sameAs(bitmap1)));
Where i called toString() it shows that, they are not the same object, although they are holding the same image as sameAs indicating.
Note:
instead of equals() method, "==" operator would do the same, there is no difference

I have two horizontal radiogroups with radiobuttons and I want to check only one of the radiobuttons but since they are in different radiogroups it allows the radiobutton from the other group to be checked too!Is there any way that when I check only one radiobutton from both groups?

You can solve your problem by listening to changes to both RadioGroups.
When a RadioButton in one RadioGroup is checked, just un-check all RadioButtons in the second RadioGroup. This is tricky, as the un-checking triggers the listener again, crashing your app. In order to prevent that, you have to add an additional condition: That the RadioButton that triggered the event got checked, not un-checked.
Here's the code:
val groupOne = findViewById<RadioGroup>(R.id.radio_group_one)
val groupTwo = findViewById<RadioGroup>(R.id.radio_group_two)
val checkedChangeListener =
RadioGroup.OnCheckedChangeListener { group, checkedId ->
val checkedButton = group.findViewById<RadioButton>(checkedId)
if (group == groupOne && checkedButton?.isChecked == true) {
groupTwo.clearCheck()
}
if (group == groupTwo && checkedButton?.isChecked == true) {
groupOne.clearCheck()
}
}
groupOne.setOnCheckedChangeListener(checkedChangeListener)
groupTwo.setOnCheckedChangeListener(checkedChangeListener)

You should to use one onClickListener for everyone button with switch case inside of it.
In every case of switch case block your should addor delete (if you have the button for deleting) one character it TextView.
After switch case block check the text length in your TextView. If the length of it equals 4, you can try to authorization or login or other actions.
Sorry for bad English.
Very interesting question first of all.
The only solution I can think of is to create a public method which will always check the length of the textview (which I think should be edittext) and add that method for every button. Once the length of the textview is 4, trigger your code you want.
Let me know if you need some more clarification
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String s=txtView.getText().toString();
if(s.length()<3){

Try adding the extra line below to your Relative Layout description:
...
android:onClick="updateRange"
android:clickable="true">
I believe to have the textview, but it cannot be cast to listview error in the following code below:
Essentially I am trying to populate information from Parse into a textfield. This I believe is the part of the code that is problematic.
here it throws a "textview cannot be cast to android.widget.listview"
public void done(List<ParseUser> userlistactivityname, ParseException e) {
if (e == null) {
for (int i = 0; i < userlistactivityname.size(); i++) {
mUserActivityNameRetrieved = (TextView) getActivity().findViewById(R.id.userlistactivityname);
mUserActivityNameRetrieved.setText(userlistactivityname.get(i).get("ActivityName").toString());
}
} else {
//else..
}
}

Thanks in advance.
you have used the ID "userlistactivityname" more than once, e.g. you define a textview and give it the id userlistactivityname, but later you also have a button with the same id "userlistactivityname"
<TextView
android:id="#+id/userlistactivityname"
...
android:divider="#null" >
</TextView>
<Button
android:id="#+id/btnMatchConfirm"
android:layout_width="100dp"
android:layout_height="50dp"
android:layout_below="#+id/userlistactivityname"
...
android:typeface="serif" />
and maybe you even have another widget defined as "userlistactivityname".
Search all your layouts for "userlistactivityname" and make sure that the id is unique!
When you want a view to be below / above / leftOf another view, you reference the view using the code
#id/view_id
when you want to add a new id to the Android R file, you use the code
#+id/new_view_id
if you use #+id/ all the time, you can create problems in your R file. Try changing all references in your code to make it cleaner, and only using #+id/ when specifying android:id
