My app. has a button which if it's presses a 2 editText fields apear , and if it's pressed again 2 other editText fields apear and so on.
I want to save all the data in this fields in arrayList (or any structure)
This is a sample of my code 1- The EditText field that apears:
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minHeight="50dp"
And This is the mainAcvtivity code :
LinearLayout lLayout;
ArrayList<String> mArray = new ArrayList<String>();
int numberOfBoxes = 2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
lLayout = (LinearLayout)findViewById(R.id.layout1);
final EditText AddEduDate = (EditText)inflater.inflate(R.layout.text, null);
final EditText AddEduInfo = (EditText)inflater.inflate(R.layout.text, null);
Button b2 = (Button)findViewById(R.id.button2);
Button b = (Button)findViewById(R.id.button1);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (lLayout.getChildAt(numberOfBoxes) == null) {
lLayout.addView(AddEduDate);
lLayout.addView(AddEduInfo);
numberOfBoxes += 2;
}
}
});
If I understand your problem properly, simple
ArrayList<String> list=new ArrayList<String>();
list.add(AddEduDate.getText().toString());
should work.

I am trying to retrieve data from Firebase Database and set them to text view. My database has different multiple child data. I want to retrieve all child in a single activity like globally. I have a different card view click in the main activity. when I click on any item it does not show the same child data with related that item. It shows single child data on every item click. How can I get them in a signal Activity on card view click? I am new to Android and I have tried multiple answers here, but failed. Can anyone help me with this?
public class GlobalActivity extends AppCompatActivity
RecyclerView mRecyclerView;
List<User> myUserList;
User mUser;
ProgressDialog progressDialog;
private DatabaseReference db;
private ValueEventListener eventListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_global);
progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Please wait its loding..");
mRecyclerView = (RecyclerView) findViewById(R.id.farazList);
GridLayoutManager gridLayoutManager = new GridLayoutManager(AhmedFarazActivity.this, 1);
mRecyclerView.setLayoutManager(gridLayoutManager);
myUserList = new ArrayList<>();
final ReAdapter reAdapter = new ReAdapter(GlobalActivity.this, myUserList);
mRecyclerView.setAdapter(reAdapter);
db = FirebaseDatabase.getInstance().getReference().child("Spinner").child("US");
progressDialog.show();
eventListener = db.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
myUserList.clear();
for (DataSnapshot ds : dataSnapshot.getChildren()) {
User userData = ds.getValue(User.class);
myUserList.add(userData);
}
reAdapter.notifyDataSetChanged();
progressDialog.dismiss();
}
#Override
public void onCancelled(DatabaseError databaseError) {
progressDialog.dismiss();
}
});
}
}
Handle to click
This is handler in the adapter when I click on any item it does not show the same child data with related that item. It shows single child data on every item click.
#Override
public void onBindViewHolder(#NonNull MyHolder holder, int position) {
// Hide data
holder.nameText.setText(models.get(position).getName());
holder.img.setImageResource(models.get(position).getImg());
holder.setItemClickListener(new ItemClickListener() {
#Override
public void onItemClick(View view, int pos) {
//Go to UK Item to show UK data
if (models.get(pos).getName().equals("US")){
//Start Display Activity on click
Toast.makeText(c, "US", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(c, GlobalActivity.class);
c.startActivity(intent);
}
//Go to UK Item to show UK data
if (models.get(pos).getName().equals("UK")){
//Start System Info Activity on click
Toast.makeText(c, "UK", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(c, GlobalActivity.class);
c.startActivity(intent);
}
}
});
}
Now i figure out my solution
I add just Intent.putExtra("data","1"); in every handler click
#Override
public void onBindViewHolder(#NonNull MyHolder holder, int position) {
// Hide data
holder.nameText.setText(models.get(position).getName());
holder.img.setImageResource(models.get(position).getImg());
holder.setItemClickListener(new ItemClickListener() {
#Override
public void onItemClick(View view, int pos) {
//Go to UK Item to show UK data
if (models.get(pos).getName().equals("US")){
//Start Display Activity on click
Toast.makeText(c, "US", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(c, GlobalActivity.class);
intent.putExtra("data","1");
c.startActivity(intent);
}
//Go to UK Item to show UK data
if (models.get(pos).getName().equals("UK")){
//Start System Info Activity on click
Toast.makeText(c, "UK", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(c, GlobalActivity.class);
intent.putExtra("data","2");
c.startActivity(intent);
}
}
});
}
In GlobalActivity i create a method for data
initialize data(); inside onCreate
public class GlobalActivity extends AppCompatActivity
RecyclerView mRecyclerView;
List<User> myUserList;
User mUser;
ProgressDialog progressDialog;
private DatabaseReference db;
private ValueEventListener eventListener;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_global);
progressDialog = new ProgressDialog(this);
progressDialog.setMessage("Please wait its loding..");
mRecyclerView = (RecyclerView) findViewById(R.id.farazList);
GridLayoutManager gridLayoutManager = new GridLayoutManager(AhmedFarazActivity.this, 1);
mRecyclerView.setLayoutManager(gridLayoutManager);
myUserList = new ArrayList<>();
final ReAdapter reAdapter = new ReAdapter(GlobalActivity.this, myUserList);
mRecyclerView.setAdapter(reAdapter);
data();
progressDialog.show();
eventListener = db.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(DataSnapshot dataSnapshot) {
myUserList.clear();
for (DataSnapshot ds : dataSnapshot.getChildren()) {
User userData = ds.getValue(User.class);
myUserList.add(userData);
}
reAdapter.notifyDataSetChanged();
progressDialog.dismiss();
}
#Override
public void onCancelled(DatabaseError databaseError) {
progressDialog.dismiss();
}
});
}
method for getting
public void data() {
String data = getIntent().getStringExtra("data");
if (data.equals("1")) {
db = FirebaseDatabase.getInstance().getReference().child("Spinner").child("India");
db.keepSynced(true);
} else if (data.equals("2")) {
db = FirebaseDatabase.getInstance().getReference().child("Spinner").child("Pak");
db.keepSynced(true);
} else if (data.equals("3")) {
db = FirebaseDatabase.getInstance().getReference().child("Spinner").child("UK");
db.keepSynced(true);
}
}
In my test app I disable expansion of AppBarLayout when it is collapsed (by scrolling RecycleView). I do that by adding addOnOffsetChangedListener to AppBarLayout.
However, when I click EditText it expands again but, I do not want it to expand.
How to disable the expansion of AppBarLayout when I click EditText?
I have put the whole code, so that everyone can copy/paste the code, create new project and test this fast.
Here is how the .gif looks

EDIT
I tried adding focus listener to EditText but, that did not helped. This is how i try:
editTextMessage.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus){
appBarLayout.setExpanded(false);
AppBarLayout.LayoutParams params = (AppBarLayout.LayoutParams) collapsingToolbarLayout.getLayoutParams();
params.setScrollFlags(0);
}
}
});
I do not know is the best solution, but it works nice. If someone has better solution, feel free to write it.
There is indeed a better, cleaner and simpler solution.
The culprit that leads to this "issue" is actually a feature that was added by Google inside AppBarLayout.ScrollingViewBehavior. That's the one you set via app:layout_behavior="#string/appbar_scrolling_view_behavior". Inside that class, onRequestChildRectangleOnScreen calls setExpanded(false, !immediate) whenever the keyboard is shown. You simply override this method and return false to disable this default behavior. Add this class to your project:
import android.content.Context;
import android.graphics.Rect;
import android.util.AttributeSet;
import android.view.View;
import androidx.annotation.NonNull;
import androidx.coordinatorlayout.widget.CoordinatorLayout;
import com.google.android.material.appbar.AppBarLayout;
public class FixedScrollingViewBehavior extends AppBarLayout.ScrollingViewBehavior {
public FixedScrollingViewBehavior() {
super();
}
public FixedScrollingViewBehavior(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
public boolean onRequestChildRectangleOnScreen(#NonNull CoordinatorLayout parent,
#NonNull View child, #NonNull Rect rectangle, boolean immediate) {
return false;
}
}
Then just use this new class by changing app:layout_behavior="#string/appbar_scrolling_view_behavior" to app:layout_behavior="your.source.package.FixedScrollingViewBehavior".
I have find the answer. I do not know is the best solution, but it works nice. If someone has better solution, feel free to write it.
So, what i done is i put the whole AppBarLayout params to 0 when i click EditText or when EditText get focus.
So, when EditText is clicked, AppBarLayout is still there but, now his height is 0 and it is not visible.
This do the trick:
//Collaps AppBarLayout
public void collapsAppBarLayout(){
CoordinatorLayout.LayoutParams params =(CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams();
params.height = 0; // setting new param height to 0
//setting params to appbarLayout (now AppBarLayout is 0)
appBarLayout.setLayoutParams(params);
appBarLayout.setExpanded(false);
}
Also, if you want to have expand option, you need to save height of previous params and then just add that height again.
So, this is a code how i done it:
Fist, when i scroll RecycleView i disable expand of appBarLayout using addOnOffsetChangedListener. However i also save params height for future use.
int sizeParams; //save params height
appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
#Override
public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
if (Math.abs(verticalOffset) == appBarLayout.getTotalScrollRange()) {
// Collapsed
Toast.makeText(MainActivity.this, "Collapsed", Toast.LENGTH_SHORT).show();
// disable expanding and scroll
AppBarLayout.LayoutParams params = (AppBarLayout.LayoutParams) collapsingToolbarLayout.getLayoutParams();
params.setScrollFlags(0);
//saving height for future use
sizeParams = params.height;
} else if (verticalOffset == 0) {
Toast.makeText(MainActivity.this, "Extend", Toast.LENGTH_SHORT).show();
// Expanded
} else {
// Somewhere in between
}
}
});
Now i make this 2 method which i call when i need expand/collaps.
//Collaps AppBarLayout
public void collapsAppBarLayout(){
CoordinatorLayout.LayoutParams params =(CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams();
sizeParams = params.height;//save params height for future use
params.height = 0; // setting new param height to 0
//setting params to appbarLayout (now AppBarLayout is 0
appBarLayout.setLayoutParams(params);
appBarLayout.setExpanded(false);
}
//Expand AppBarLayout
public void expandAppBarLayout(){
CoordinatorLayout.LayoutParams params =(CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams();
params.height = 3*sizeParams; // HEIGHT
appBarLayout.setLayoutParams(params); //add height to appbarlayout
//enable scroll and expand
AppBarLayout.LayoutParams params1 = (AppBarLayout.LayoutParams) collapsingToolbarLayout.getLayoutParams();
params1.setScrollFlags(1);
appBarLayout.setExpanded(true);//expand
}
Using eclipse i was able to get edittext value from separate onclicklistener class, but after i transfer the same style of code to android studio 3 the edittext returns empty here is my code
public class MainActivity extends AppCompatActivity {
Button btnGenerate;
private static final String TAG = MainActivity.class.getSimpleName();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//getting the generate_btn actually works
btnGenerate = findViewById(R.id.generate_btn);
btnGenerate.setOnClickListener(new OnClickListenerGenerate());
}
}
And here is the OnClickListener class
public class OnClickListenerGenerate implements View.OnClickListener {
EditText second_digit;
private static final String TAG = OnClickListenerGenerate.class.getSimpleName();
#Override
public void onClick(View view) {
final Context context = view.getRootView().getContext();
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View formElementsView = inflater.inflate(R.layout.activity_main, null, false);
second_digit = formElementsView.findViewById(R.id.txtSecondDigit);
//returns empty
Log.d(TAG, ">>" + second_digit.getText().toString());
}
}
I found the answer from this link Android::findViewByID - how can I get View of a TextView through a Listener of another UI element? and now it's working.
class ButtonListener implements android.view.View.OnClickListener {
public void onClick(View v) {
View parent = (View)v.getParent();
if (parent != null) {
TextView txtView = parent.findViewById(R.id.mytextview);
txtView.setText(...);
}
}
}
I am using a spinner and an arrayAdapter to populate items in spinner. I want to make the spinner multi-selectable but I just select one row.I searched in Google, solution available in Java, but i don't have any idea on how to implement it in Xamarin.
My code is as below,
adapterList= new ArrayAdapter<string>(this, Android.Resource.Layout.SimpleListItemMultipleChoice);
spnMultiTest.Adapter = adapterList;
I want to make the spinner multi-selectable but I just select one row.I searched in Google, solution available in Java, but i don't have any idea on how to implement it in Xamarin.
Basically I just translate the codes from Android Spinner with multiple choice
to Xamarin codes. I have tested it and it works fine:
MultiSpinner.cs:

I built a webservice and tested it with SoapUI and everything is ok. Now when I try to submit the form to register an user, I get NetworkOnMainThreadException error. It looks the main thread is having to much work.
Can you help me with AsyncTask and doInBackground() method? Where and how should I do that? On my user register layout class (RegUser.java) or where the insert method is (UserDAO.java)?

I should do it in the userDOA.java. The ASynctask will look like this.
AsyncTask<String, Void, Boolean) task =new AsyncTask<String, Void, Boolean>() {
#Override
protected Boolean doInBackground(String... params) {
HttpTransportSE http = new HttpTransportSE(URL);
try {
http.call("urn:" + INSERIR, envelope);
SoapPrimitive resposta = (SoapPrimitive) envelope.getResponse();
return Boolean.parseBoolean(resposta.toString());
} catch (Exception e) {
//handle exception
}
}
#Override
protected void onPostExecute(Boolean result) {
//Do something with result
}
}
You need to call it like
task.execute(params);
Hope this helps.
