Android Studio - Database fetch to Textview not displaying correctly

I'm trying to display read from table in database, what i have written so far passes the json, however rather than showing in textview - it displays as a short popup, and then disappears.

}
return sb.toString().trim();
} catch (Exception e) {
return null;
}
}
}
DownloadJSON getJSON = new DownloadJSON();
getJSON.execute();
}
private void setTextView(String json) throws JSONException {
JSONArray jsonArray = new JSONArray(json);
String[] tasks = new String[jsonArray.length()];
for (int i = 0; i < jsonArray.length(); i++) {

}

builder.setIcon(R.drawable.alert);
builder.setTitle(" ");
builder.setMessage("Lockdown sucks, we know.\nThat's why we created W2D.\n\nOver the comings weeks/months, we'll be adding some cool stuff here. So bear with...\n\nStay Home\nProtect the NHS\nSave Lives");
// Create and show the AlertDialog
final AlertDialog alertDialog = builder.create();
alertDialog.show();
}
#Override
public void finish() {
super.finish();
overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_right);
}
}
I have a funny feeling this is something about me having a button requesting a pop-up too in the code, perhaps I haven't integrated the 2nd onCreate properly?
The above is linked to a textview on activity_tasks.xml
Example on phone:

What you are seeing at the bottom is the toast you create in onPostExecute(). You receive the data, but then never update the text of the TextView. In setTextView() you could also do that:
textView.setText(json);
On another note: Don't use AsyncTasks anymore. They are deprecated and way too laborious. Also, to read the Json much more easily, you can use a library like Gson or Moshi.

ViewPager2 with RecyclerView not displaying correctly

I've been working on an app that uses a vertical RecyclerView inside a fragment, all inside a ViewPager2 object with a tabLayout. I can't seem to figure out how to make all these things work together. Currently, it looks like I got it to show the recycler view with the data but the tabs aren't showing up and the items in the list are spaced like they're different pages. Could someone explain how I'm messing up?
It looks like this:
I'd like it to be like this:

for tablayout :
take/make tablayout outside the CollapsingToolbarLayout
and for "list are spaced" :
make wrap_content height in view_page code
also list_view LinearLayout height to wrap_content
hope it helped :)

In your list_view , Use your parent layout height wrap_content not match_parent

where to put android.support.v4.widget.SwipeRefreshLayout and how to implement it?

just wanna ask where to put the android.support.v4.widget.SwipeRefreshLayout on my codes? I'm confused if it should be on my activity_main.xml or in my list_item.xml file..
Here is my activity_main.xml:

Thanks!

To add the swipe to refresh widget to an existing app, add SwipeRefreshLayout as the parent of a single ListView or GridView. Remember that SwipeRefreshLayout only supports a single ListView or GridView child. - Add the SwipeRefreshLayout Widget
So, your activity_main.xml should be like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</android.support.v4.widget.SwipeRefreshLayout
</LinearLayout>
Implementation:
public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener{
private SwipeRefreshLayout swipeRefreshLayout
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
swipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.swipeLayout);
swipeRefreshLayout.setOnRefreshListener(this);
//to change the color of the refresh indictor
swipeRefreshLayout.setColorScheme(getResources().getColor(R.color.yourcolor),
getResources().getColor(R.color.yourcolor),
getResources().getColor(R.color.yourcolor),
getResources().getColor(R.color.yourcolor));
}
#Override
public void onRefresh() {
//do something here
//setRefreshing(false) will hide the indicator
swipeRefreshLayout.setRefreshing(false);
}
}

It should wrap around the listview, something like this:
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/swiperefresh"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="8dp">
<android.widget.ListView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.widget.ListView>
</android.support.v4.widget.SwipeRefreshLayout>
If you're using Android Studio, you can look at a Swiperefresh sample:
File\New\Import Sample\ then search for "swipe..."
In your java code, you initialize the SwipeRefresh object exactly how you would do a TextView, Button or anything else, except in your onResume(), you also want to put something like this:
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
initiateRefresh();
}
});
and then inside initiateRefresh(), you do something like:
AssignData2ListView();
mSwipeRefreshLayout.setRefreshing(false);

Show catched JSON object from PHP in android application

I'm going to create a simple register form app that when user insert their username and password, EditText in UI shows the id of their record in database.
My app insert users into database correctly and show JSON output into EditText.
For Example when I insert first user to my database, EditText show this:
{
"id": "1", "0":"1"
}
But, I want show this in EditText:
1 instead of
{
"id" : "1", "0" : "1"
}

Any suggestion, would be appreciated ...

Your response from PHP for user id=17 is {"id":{"0":"17","id":"17"}}
Try to change in php script
//$response = array("id" => $id_result);
$response["id"] = $id_result["id"];
then your rsponse will be {"id":"17"}

In your class InsertClass and function doInBackground() where you are converting result string to JsonObject like
json = sb.toString();
jObj = new JSONObject(json);
Add code:
String result = jObj.getString ("id");
Return result;

Handeling adapters from list view to single item view class

I have a class viewroom.java, to list all the rooms' title from database, as follows:

JSONObject c = room.getJSONObject(i);
// Storing each json item in variable

// adding HashList to ArrayList

} catch (JSONException e) {
e.printStackTrace();
}
/**
* Updating parsed JSON data into ListView

ListAdapter adapter = new SimpleAdapter(this, roomList,
R.layout.list_room,
new String[] { TAG_TITLE, TAG_LOCATION, TAG_PRICE }, new int[] {

setListAdapter(adapter);
// selecting single ListView item
ListView lv = getListView();
// Launching new screen on Selecting Single ListItem
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
String title = ((TextView) view.findViewById(R.id.title)).getText().toString();
String location = ((TextView) view.findViewById(R.id.location)).getText().toString();
String price = ((TextView) view.findViewById(R.id.price)).getText().toString();
// Starting new intent
Intent in = new Intent(getApplicationContext(), SingleRoomActivity.class);
in.putExtra(TAG_TITLE, title);
in.putExtra(TAG_LOCATION, location);
in.putExtra(TAG_PRICE, price);
startActivity(in);
}
});
}
}
when one of those list item is clicked, details are shown in single Room Activity class. it
is as follows:
package com.iwantnew.www;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.TextView;
public class SingleRoomActivity extends Activity {
private static final String TAG_TITLE = "title";
private static final String TAG_LOCATION = "location";
private static final String TAG_PRICE = "price";
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.single_room);
// getting intent data
Intent in = getIntent();
// Get JSON values from previous intent
String title = in.getStringExtra(TAG_TITLE);
String location = in.getStringExtra(TAG_LOCATION);
String price = in.getStringExtra(TAG_PRICE);
// Displaying all values on the screen
TextView lblTitle = (TextView) findViewById(R.id.title_label);
TextView lblLocation = (TextView) findViewById(R.id.location_label);
TextView lblPrice = (TextView) findViewById(R.id.price_label);
lblTitle.setText(title);
lblLocation.setText(location);
lblPrice.setText(price);
}
}
there remains a big gap between each items in view room activity class, when all details are shown in single room activity.
and when list adapter is modified to
ListAdapter adapter = new SimpleAdapter(this, roomList,
R.layout.list_room,
new String[] { TAG_TITLE }, new int[] {
R.id.title });
in view room activity, the gap vanishes but, single room activity does not show all the description.
