I have an FragmentActivity which contain WebView, Edittext1, Edittext2, Checkboxes and button. When I click the button in fragment it will move to Results_activity. And if I click button from Results_activity it move back to FragmentActivity.
But my edittext values getting cleared while moving back.

}

Replace the method like this,
mainView.findViewById(R.id.check_results).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});

custom view with overlapping

I define layout row which I inflate and add view pragmatically to a linear layout.
I wanna something like this,
https://i.stack.imgur.com/EKPmJ.png
Here is xml of my main activity where I am inflating the costume view row
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

<LinearLayout
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/list_container">
</LinearLayout>
</LinearLayout>
here is my xml code of row which I am inflating:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher_round"/>
</RelativeLayout>
here is my java code
public class MainActivity extends AppCompatActivity {
Button b;
LinearLayout l1;
Context context;
Boolean isViewCreated = false;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final String Namearray[] = {"sagar", "ranjeet", "akash", "kate"};
this.context = this;
b = (Button) findViewById(R.id.inflate);
l1 = (LinearLayout) findViewById(R.id.list_container);
createViews(Namearray);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(l1.getVisibility() == View.VISIBLE && isViewCreated)
{
l1.setVisibility(View.GONE);
}
else
{
l1.setVisibility(View.VISIBLE);
}
}
});
}
void createViews(final String[] namearray)
{
for(int i=0;i < namearray.length;i++){
final int j = i;
View view = LayoutInflater.from(context).inflate(R.layout.layout_item,null);
TextView button1 = (TextView) view.findViewById(R.id.name);
Button button2 = (Button) view.findViewById(R.id.nameButton);
button1.setText("HELLO " + namearray[i]);
button2.setText("Click to know my name ");
button2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(context,"Hello " + namearray[j],Toast.LENGTH_LONG).show();
}
});
view.setId(generateViewId());
try {
l1.addView(view);
isViewCreated = true;
}
catch (Exception e)
{
}
}
l1.setVisibility(View.GONE);
}
private static final AtomicInteger viewIdGenerator = new AtomicInteger(15000000);
public static int generateViewId() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
return generateUniqueViewId();
} else {
return View.generateViewId();
}
}
private static int generateUniqueViewId() {
while (true) {
final int result = viewIdGenerator.get();
// aapt-generated IDs have the high byte nonzero; clamp to the range under that.
int newValue = result + 1;
if (newValue > 0x00FFFFFF) newValue = 1; // Roll over to 1, not 0.
if (viewIdGenerator.compareAndSet(result, newValue)) {
return result;
}
}
}
}
but when I inflate row my image view get cutoff which I not want I tried with negative margin but it not work
here what it looks like
custom overlapping row
what I do so I over lap image to above view?

Try changing your layout to 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="match_parent"
android:orientation="horizontal">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="its text view"
/>
<Button
android:id="#+id/nameButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/name"
/>
</RelativeLayout>
<ImageView
android:layout_marginTop="25dp"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher_round"/>
</RelativeLayout>
When you put in another row, that row needs to be pushed up so the android icon that is there now overlays it.

Edit text save text after reopen fragment

Hi all i have a problem with edit text in frament. This elemtn save text after reopening this fragment. It can reproduce if i do this steps
open activity -> open FragmentA ->open FragmentB (with edittext in it)->backPress(and open again FragmentA) -> open FragmentB (again)
After this steps if i am typed before some text its fill it again. I am add this in code: writeReviewText.setText(""); and in xml : android:text="" but nothing helps. It`s look like state of fragment is saves.

And here code how i am open fragment in activity:

}
if (index == 1 || index == 2)
DeleteAllFragmentsBackstack();// need for detect if google map is initialize and already in backstack
Fragment fragment;
fragment = getSupportFragmentManager().findFragmentByTag(ReadReviewFragment.class.getClass().getSimpleName());
if (fragment == null) {
if (fragment == null) {
fragment = fragmentArray[index];
}
} else {
fragment = fragmentArray[index];
}
Log.e(TAG, "Open fragment is " + fragment);
if (fragment.getArguments() != null) {
fragment.getArguments().clear(); //for clear arguments if they saved from previous open of fragment(happens when open photos fragment)
}
if (bundle != null) {
if (fragment.getArguments() == null) {
fragment.setArguments(bundle);
} else {
fragment.getArguments().clear();
fragment.setArguments(bundle);
}
}
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.container, fragment, fragment.getClass().getSimpleName());
if (addToBackStack) {
transaction.addToBackStack(fragment.getTag());
} else {
transaction.addToBackStack(null);
}
transaction.commitAllowingStateLoss();
Log.e(TAG, "Transaction commit");
currentIndex = index;
if (index == 0 || index == 1 || index == 2) {
SetVisualTabs(index);
}
}
I am debug my code and bundle is empty when i am open FragmentB. And fragmentArray its array of fragments like:
public final Fragment[] fragmentArray = new Fragment[]{
new FragmentA(),//0
new FragmentB(),//1

onBindViewHolder is not called when I am adding Item in RecyclerView

I am doing chat application. I am using Recyclerview to show the chat to users. If I add a new item to the Recyclerview I am facing two issues. First one is onBindViewHolder is not working second one is scrollToPosition is not working. Sometimes it's working properly but sometimes I am getting these issue's again and again.
Here I have added the initialisation of RecyclerView
compile 'com.android.support:recyclerview-v7:23.2.0'
LinearLayoutManager mLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(mLayoutManager);
ArrayList<String> as = cd.messagesid(dialog.getDialogId());
adapter = new ChatAdapter(_activity, cd.messages(dialog.getDialogId()), as);
recyclerView.setAdapter(adapter);
I am using below method in adapter page to add a new item.
public void add(QBChatMessage qb) {
chatMessages.add(qb);
messageidis.add(qb.getId());
notifyItemInserted(chatMessages.size() - 1);
}
I am using below methods to add item into the recyclerview and to scroll down the recyclerview.
private void scrollDown() {
// messagesContainer.scrollToPosition(adapter.getItemCount() - 1);
// messagesContainer.smoothScrollToPosition(adapter.getItemCount() - 1);
messagesContainer.scrollToPosition(adapter.getItemCount() - 1);
}
Boolean cc = cd.Insert_tbl_chathistory(msg.getDialogId(), msg.getSenderId() + "", msg.getBody(), msg.getId() + "", msg.getDateSent(), "", msg.getReadIds() + "", msg.getDeliveredIds() + "", msg.getRecipientId() + "", 1, 0, "");
if (cc) {
msg.setProperty("SenderID", msg.getSenderId() + "");
runOnUiThread(new Runnable() {
#Override
public void run() {
adapter.add(msg);
scrollDown();
}
});
}

How can i show this dialog exactly at center of parent.?

The best way is to change your layout like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:id="#+id/relativeLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
>
try it and let me know if it works.
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/imageView"
android:layout_gravity="center_horizontal|bottom"
android:gravity="center_horizontal"
android:text=""
android:textColor="#000000" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imageView"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/imageView"
android:gravity="center" >
<Button
android:id="#+id/btnArrowRight"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/btn_arrow_right" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/imageView"
android:layout_alignParentLeft="true"

android:gravity="center" >
<Button

android:layout_width="wrap_content"
