Add button at end Listview android - java

so , i have a Listview activity , that is populated by values from a SQLITE database.
how can i put a button fixed at top or bottom ?
<?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"
android:orientation="horizontal" >
<TextView
android:id="#+id/coligada"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:layout_toEndOf="#+id/coligada" />
</RelativeLayout>
Here is my ProductAdapter that have custom layout where have the items and a apdater that populate my listview with values from Sqlite database.
package br.exemplosqlite;
import android.content.Context;
import android.content.Intent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.RelativeLayout;
import android.widget.TextView;
import java.util.List;
public class ProdutosAdapter extends BaseAdapter {
private Context context;
private List<Produtos> list;
public ProdutosAdapter(Context context, List<Produtos> list){
this.context = context;
this.list = list;
}
#Override
public int getCount() {
// TODO Auto-generated method stub
return list.size();
}
#Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return list.get(arg0);
}
#Override
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return list.get(arg0).getId();
}
#Override
public View getView(int position, View arg1, ViewGroup arg2) {
final int auxPosition = position;
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final RelativeLayout layout = (RelativeLayout) inflater.inflate(R.layout.produtos, null);
TextView tv = (TextView) layout.findViewById(R.id.coligada);
tv.setText(list.get(position).getItem());
Button editarBt = (Button) layout.findViewById(R.id.editar);
editarBt.setOnClickListener(new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
Intent intent = new Intent(context, NewUserActivity.class);
intent.putExtra("item", list.get(auxPosition).getItem());
intent.putExtra("quantidaderm",list.get(auxPosition).getQuantidaderm());
intent.putExtra("id", list.get(auxPosition).getId());
context.startActivity(intent);
}
});
// *********** BOTÃO DE EXCLUIR ***************** //
//Button deletarBt = (Button) layout.findViewById(R.id.deletar);
//deletarBt.setOnClickListener(new Button.OnClickListener(){
// #Override
// public void onClick(View arg0) {
// BD bd = new BD(context);
// bd.deletar(list.get(auxPosition));
//
// layout.setVisibility(View.GONE);
// }
//}
///);
return layout;
}
}

Try the following xml at the bottom of ListView and centerHorizontal
<?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">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<Button
android:id="#+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Your Button"
/>
</RelativeLayout>
Hope this helps.

Do it like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your text here"/>
</LinearLayout>

Try this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="vertical" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.05"
android:orientation="horizontal" >
<TextView
android:id="#+id/coligada"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/editar"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_weight="1"
android:text="Large Text" />
<Button
android:id="#+id/editar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toEndOf="#+id/coligada"
android:layout_toRightOf="#+id/coligada"
android:onClick="editar"
android:text="Quantidadesxsx" />
</LinearLayout>
</LinearLayout>

Try this.
<Button
android:id="#+id/btn"
layout_width="wrap_content"
layout_height="wrap_content"
android:alignParentTop="true"
/>
<ListView
layout_width="wrap_content"
layout_height="wrap_content"
android:layout_below="#+id/btn"
/>

Current layout is for listview items.
Remove Button from this layout file and paste it in layout file where you have defined ListView.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" >
<ListView
.....
</ListView>
<Button>
</Button>
</RelativeLayout>
in one layout and
<TextView>
</TextView>
in another layout

In button add this line of code
<Button
android:id="#+id/editar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Quantidadesxsx"
android:onClick="editar"
android:layout_below="#+id/coligada"/>

You can use android:layout_weight="1" with LinearLayout.
Example.
<?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="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/txtView"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<Button
android:id="#+id/editar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Quantidadesxsx"
android:onClick="editar"/>
</LinearLayout>

Do not return back to code from onClickListener onClick method

This part of the code is to add 3 EditText lines while the button secbutt is clicked. While all three EditText lines are on the screen, the button should disappear.
Now I do not understand why after entering onClick method and starting plusTextField method, it just adds EditText lines infinitely. I want it to execute once and to return to the beginning of summonButton method. What should I do?
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
public class MainActivity extends AppCompatActivity {
int numberOfLinesLeft = 3;
Button secondaryActivityAddButton;
LinearLayout llForSecondaryButton;
LinearLayout llForSecondaryEditText;
EditText et;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void summonButton(View view){
llForSecondaryButton = findViewById(R.id.secondaryButton);
secondaryActivityAddButton = new Button(this);
secondaryActivityAddButton.setText("" + numberOfLinesLeft);
llForSecondaryButton.addView(secondaryActivityAddButton);
secondaryActivityAddButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
plusTextField();
}
});
}
public void plusTextField() {
llForSecondaryEditText = findViewById(R.id.linearLayout1);
// add edittext
et = new EditText(this);
et.setText("text" + numberOfLinesLeft);
llForSecondaryEditText.addView(et);
numberOfLinesLeft--;
}
}

You miss logic of setting the button invisible when counter riches 0 :
public void onClick(View view) {
plusTextField();
if(numberOfLinesLeft == 0) {
view.setVisibility(View.GONE);
}
}
Here is the result, there is no button after adding 3 Edit Texts:

Managing onClickListeners in more then one xml file

I created an app that adds forms dynamically when a user clicks the add butting and deletes it when he clicks the cancel button. I have two cancel buttons, one in the Field.xml file and the other in the activity_school_search_setup file.
They both have the same ID but the one in the Field.xml file does not delete the field. It appears as though the onclicklistener does not function for the delete button.

You either should add a clickListener on
View rowView = inflater.inflate(R.layout.field, null);
Or add android:onClick within an element of field.xml if you want some click event to happen on it.
initializeListenners(); is only called once, during the initial layout, not on dynamic view additions.

Implement OnClickListener for Field.xml button after you inflate that layout.
Here is example:
public void addNewClass(){
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.field, null);
final Button btnDelete = rowView.findViewById(R.id.delete_button);
btnDelete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Your stuff
}
});
schoolSetupLayout.addView(rowView, schoolSetupLayout.getChildCount() -1);
}
Hope that help :)

Dynamically generated delete button does not respond to an OnclickListener(Android JAVA)

I created an app that dynamically adds an edittext field to the view by clicking an Add button and deletes it by clicking a delete button. I created a separate xml file called field.xml that is called up when a new edittext field is added to the view. But the delete button does not remove this edittext field when clicked. What am I missing in the code I have tried most options but to no avail.
Here is the main java file
SchoolSearchSetup.java

Have you tried using
setVisibility(View.GONE);
Update:
Try this code block:
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
Button btn = new Button(this);
btn.setId(i);
final int id_ = btn.getId();
btn.setText("button " + id_);
btn.setBackgroundColor(Color.rgb(80, 80, 90));
linear.addView(btn, params);
btn1 = ((Button) findViewById(id_));
btn1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Toast.makeText(view.getContext(),
"Button clicked index = " + id_, Toast.LENGTH_SHORT)
.show();
}
});

How to open fragments containing webViews in another activity on button click from fragments of another activity?

These are the files in which i want that if i click on about_img_btn then it should open a fragment containing a webView in another activity. The same should be repeated for all the buttons.
Please define the further code that i have to use and mention the files where i have to use it. Thanks!

try this:
in your fragment_lower_main xml:
Give an id to the Framelayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.administrator.hiha.Lower_main_Fragment">
<FrameLayout
android:id="+#id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<--Rest of the code -->
/>
</LinearLayout>
Now in code open new Fragment during button click using:
about_img_btn=(ImageButton)rootView.findViewById(R.id.about_img_btn);
about_img_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
AboutUS fragment = new AboutUS();
Replace_fragment(fragment); //pass the fragment u want to replace
}
});
public void ReplaceFragment(Fragment r_fragment) {
FragmentManager fragmentManager = getActivity.getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment_container, r_fragment).commit();
}

Android background color for accordion menu

I want the code in the Java file to set the background color of whatever button was clicked, and keep it, even after you let go of the button. Thanks in advance
I don't really get the formatting on here. I hope it's clear what belongs where.
Java:
package mika.actual;

import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class accordion extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.accordian);
Button btnProfile = (Button) findViewById(R.id.btnProfile);
Button btnSettings = (Button) findViewById(R.id.btnSettings);
Button btnPrivacy = (Button) findViewById(R.id.btnPrivacy);
View panelProfile = findViewById(R.id.panelProfile);
panelProfile.setVisibility(View.GONE);
View panelSettings = findViewById(R.id.panelSettings);
panelSettings.setVisibility(View.GONE);
View panelPrivacy = findViewById(R.id.panelPrivacy);
panelPrivacy.setVisibility(View.GONE);
btnProfile.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// DO STUFF
View panelProfile = findViewById(R.id.panelProfile);
panelProfile.setVisibility(View.VISIBLE);
View panelSettings = findViewById(R.id.panelSettings);
panelSettings.setVisibility(View.GONE);
View panelPrivacy = findViewById(R.id.panelPrivacy);

If I understood correctly, what you want to do is, when clicking a button and expanding its sub-menu, change the background of that button until it is clicked again. You can do this with a Tag on the Button:
btnSettings.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// DO STUFF
//if button is not selected, change background and tag the View as selected
if(v.getTag() == null || v.getTag().equals("not_selected")) {
v.setBackgroundColor(Color.RED);
v.setTag("selected");
//show sub-menu
}
//if button is already selected, reset background and tag the View as not selected
else{
v.setBackgroundResource(android.R.drawable.btn_default);
v.setTag("not_selected");
//hide sub menu
}
}
});
Notice that v.setBackgroundResource(android.R.drawable.btn_default); is resetting the Button background to an android drawable. You may want to change this to a custom drawable or color.
You could have used an ExpandableListView to implement this kind of menu.

button.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
view.setBackgroundColor(ContextCompat.getColor(context, R.color.presed_color));
} else if (event.getAction() == MotionEvent.ACTION_UP) {
view.setBackgroundColor(ContextCompat.getColor(context, R.color.unpresed_color));
}
return false;
}
});
