I am using frame layout for that. but still not able to make those buttons visible overview pager. only fragments in my view pager are visible but the buttons which I want to show over viewpager pager are not getting visible.

How do I get each textview resource amount and add them all together into a single variable to be converted into a two sliced pie chart?

This is the code I have been working on for a while. The only issue is I cannot seem to be able to get the sum of values input into the editText fields that are dynamically added into the program and then place them into a pie chart. The data is to be transferred from the second activity to the third where the third activity will add up all resource amounts and display them into a pie chart.

Data doesn't show in recyclerView, need to go back to show it

I want to create an activity to search for users by full name. I created everything I needed and it worked properly, except for one thing. When I press search button the result are not show in recyclerview. I need to go back and the the results are shown. I need to do these 2 steps to see the results.
Yes the search bar and view holder are overlap, I will try to fixed later. Do you know how to make it so that once searched the results are displayed immediately without having to go back

I think it's the RecyclerView in your XML that needs to be adjusted at android:layout_height = "0dp"
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"

In the code, I want to add Conform button click listener event call Android back button. Like click on back button in fragment close fragment in this time.
public void pushFragment(Fragment fragment, boolean shouldAdd, Bundle bundle) {
stackFragmentMain.push(fragment);
FragmentManager man = getSupportFragmentManager();
FragmentTransaction ft = man.beginTransaction();
ft.replace(R.id.main_screens, fragmentholder.fragment);
ft.commitAllowingStateLoss();
}
public void popFragment() {
if (stackFragmentMain.size() >= 1) {
Fragment fragment = stackFragmentMain
.elementAt(stackFragmentMain.size() - 2);
stackFragmentMain.pop();
if (fragmentholder != null) {
FragmentManager man = getSupportFragmentManager();
FragmentTransaction ft = man.beginTransaction();
ft.replace(R.id.main_screens, fragmentholder.fragment);
ft.commitAllowingStateLoss();
}
}
}
EDIT
Change the following part of your onClick method :-
ChangPass changPass = new ChangPass();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.chg_frag,changPass);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
fragmentTransaction = fragmentManager.beginTransaction();
to
ChangPass changPass = new ChangPass();
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.chg_frag,changPass);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
fragmentManager.executePendingTransactions();
EDIT 2
Along with the above change, in your Conform.onClickListener() of your ChangePass fragment, add the following code :-
getActivity().getSupportFragmentManager().popBackStack();

changing activity on android

I've difficult with changing activity on android.

First of all Use setContentView(R.layout.main) in onCreate() in your oncreate as Akhil mentioned instead of inflating.
Also to set background image to your activity use android:background="#drawable/image_name" to your root container in main.xml.
If you are trying to dynamically switch the image in your lisenter.
Try and let us know if it worked.
Also to get more understanding can to show contents of your main.xml ?

Why my Android application is eating so much RAM?

I have an Android application with a very simple main activity. It only has two buttons, one textview and one edittext field. I launch the main activity (I don't do anything, just launch it from app drawer), then I press home button to get to my home screen, go to settings > appmanager > running > cached background processes and there I see that my app is eating more RAM than other cached background processes, around 8 MB of RAM. Is it normal? Why is it eating more than other apps? This is my code:
MainActivity:
package com.example.myapp;
import android.app.ActivityManager;
import android.content.ComponentName;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.app.ActionBarActivity;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}
ActivityManager am = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
int memoryClass = am.getMemoryClass();
long maxMemory = Runtime.getRuntime().maxMemory();
long totalMemory = Runtime.getRuntime().totalMemory();
Log.i("ilog", "memoryClass: " + memoryClass);
Log.i("ilog", "maxMemory: " + maxMemory);
Log.i("ilog", "totalMemory: " + totalMemory);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

button1.setOnClickListener(new View.OnClickListener() {

Intent callImitateIntent = new Intent(getActivity(), CallReceiver.class);

So can anyone tell me why is it eating so much RAM? Thanks in advance!
