Link CheckBox with Checkable Interface for a ListView

For my Android application I have implemented a ListView that is populated by a Custom Adapter from BaseAdapter and a custom Layout for the rows.
Now i would like to make entries checkable by using the corresponding methods from ListView, like setItemChecked() or getCheckedItemCount().
I created a custom Layout class for the row layout that imlpements Checkable interface and retrieved the Button using findViewById to be able to access it inside the overridden methods from Checkable.
When long clicking on an entry in the list, the methods get invoked, but I get a NullpointerException, saying the CheckBox is referencing null:
java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.CompoundButton.setChecked(boolean)' on a null object reference
What is the appropriate way to link the checkbox of each entry inside a checkable Layout?
The checkable Layout class looks like this:
package com.lastname.name.arcadaobjecttracker;
import android.content.Context;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.CheckBox;
import android.widget.Checkable;
import android.widget.LinearLayout;
//extend the Layout for the row view (each element in the listView) to add support for checkable rows (called by the listView methods like setItemChecked() etc.)
public class CheckableRowLayout extends LinearLayout implements Checkable
{
View view;
CheckBox checkBox;
public CheckableRowLayout(Context context)
{
super(context);
init(context);
}
public CheckableRowLayout(Context context, #Nullable AttributeSet attrs)
{
super(context, attrs);
init(context);
}
public CheckableRowLayout(Context context, #Nullable AttributeSet attrs, int defStyleAttr)
{
super(context, attrs, defStyleAttr);
init(context);
}
private void init(Context context)
{
checkBox = (CheckBox) findViewById(R.id.checkBox);
}
#Override
public void setChecked(boolean checked)
{
checkBox.setChecked(checked);
}
#Override
public boolean isChecked()
{
return checkBox.isChecked();
}
#Override
public void toggle()
{
checkBox.toggle();
}
}
The Layout consists of the following xml file with checkbox:
<?xml version="1.0" encoding="utf-8"?>
<com.lastname.name.arcadaobjecttracker.CheckableRowLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

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();
}

Add button at end Listview android

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:text="Large Text"
android:layout_alignBottom="#+id/editar"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
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"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/coligada"
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>

Android: EditText in CustomView not behaving as expected when touched

I have a CustomView which contains a LinearLayout that holds an EditText & another custom view element. However, when I run my app and touch the EditText it does not behave as expected (doesn't appear to receive focus & the soft keyboard doesn't open). I've tried setting duplicateParentState="true" on both the EditText & the LinearLayout. I also attached an onTouchEventListener to the EditText that calls a simple toast & the toast did show up.
Here's the code for my CustomView.

Min SDK Version is set at 14, target is set at 20. Any help would be greatly appreciated!
EDIT:
I got this logcat message today while testing long presses on my FormFields.
W/TextView﹕ TextView does not support text selection. Action mode cancelled.
I double checked my code and the EditText element is only ever cast as an EditText. If the EditText is being cast to a TextView that would explain my original issues but now I'm confused as to why or how it was cast as a TextView.

It looks like you are extending LinearLayout but never using it in your layout. From what you've posted, you aren't using the FormField at all and the only custom View I see is the ValidationIcon view. So hooking the touch events into EditText and ValidationIcon aren't occurring because you aren't using FormField in your layout.xml.
Rather than extending LinearLayout, why not just use the predefined methods and attributes to handle the behaviour you are trying to achieve. For example, displaying keyboard, requesting focus, and displaying hint:
<EditText
android:id="#+id/edit_text"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
**android:inputType="text"**
**android:hint="#styleable/FormField_fieldInputHint"**
android:padding="10dp"
android:textColor="#2d6169"
android:textSize="18sp"
android:background="#color/transparent" />
The keyboard should display when the edit text receives focus, if not you could programmatically do this by requesting focus and handling the IME manager call. For example, from the Activity/Fragment:
//call this from onViewCreated to grab focus and begin the flow
editText.requestFocus();
//set focus listener to handle keyboard display
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (!hasFocus) {
InputMethodManager imm = (InputMethodManager)getSystemService(
Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(myEditText.getWindowToken(), 0);
} else {
InputMethodManager imm = (InputMethodManager)getSystemService(
Context.INPUT_METHOD_SERVICE);
imm.showSoftInputFromWindow(myEditText.getWindowToken(), 0);
}
});

Make sure have not been setting inputType:'none' or '0X000000'

use this code for custom Edittext with title

How to add icon to tabs

I am trying to add an icon to my tabs and it isnt working,
I tried adding
getResources().getDrawable(R.drawable.bodyicon));
and it still isnt working. When I run the application the tab bar just has the text and there is no icon
I outlined where my code is. If someone could figure out why it isnt working that would be great.

My tip is to get access to the tab title textview and set left|top|right|bottom drawable
Example:
//to get first tab title as textView from tabHost
TextView tabTitle = (TextView) tabHost.getTabWidget().getChildAt(0)
.findViewById(android.R.id.title);
//to set the icon to left of the tab title
tabTitle.setCompoundDrawablesWithIntrinsicBounds(
getActivity().getResources().getDrawable(
R.drawable.ic_tab_icon), null, null, null);

I have two physical devices one 2.2 and the other 4.2.2. on 2.2 there is no issue and the icon appears. on 4.2.2 there is no icon. Somethings changed in how tabs are laid out in Android. If you really required to use a TabHost i saw you can pass in a view as the tabindicator. This code is kinda pseudo code as it still some adjustment in the UI in terms of layout but try this:
define a layout called tabindicator_layout.xml and put it in res/layout. the contents of which look like this:
<?xml version="1.0" encoding="utf-8"?>
<ImageView
android:id="#+id/image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal|top"
android:scaleType="center" >
</ImageView>
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal" />
then in your class code at runtime inflate this view and populate the image and textview with what you desire. do this for each tab:
//*********************below are my tabs*******************************************
th.setup();
TabSpec specs = th.newTabSpec("Front");
specs.setContent(R.id.Front);
View tabIndicator = LayoutInflater.from(this).inflate(
R.layout.tabindicator_layout, th.getTabWidget(), false);
((TextView) tabIndicator.findViewById(R.id.title)).setText("Front");
((ImageView) tabIndicator.findViewById(R.id.image))
.setImageResource(R.drawable.ic_launcher);
specs.setIndicator(tabIndicator);
TabSpec specs2 = th.newTabSpec("tag2");
specs2.setContent(R.id.Back);
View tabIndicator2 = LayoutInflater.from(this).inflate(
R.layout.tabindicator_layout, th.getTabWidget(), false);
((TextView) tabIndicator2.findViewById(R.id.title)).setText("Back");
((ImageView) tabIndicator2.findViewById(R.id.image))
.setImageResource(R.drawable.ic_launcher);
specs2.setIndicator(tabIndicator2);
TabSpec specs3 = th.newTabSpec("tag3");
specs3.setContent(R.id.tab3);
View tabIndicator3 = LayoutInflater.from(this).inflate(
R.layout.tabindicator_layout, th.getTabWidget(), false);
((TextView) tabIndicator3.findViewById(R.id.title)).setText("...More");
((ImageView) tabIndicator3.findViewById(R.id.image))
.setImageResource(R.drawable.ic_launcher);
specs3.setIndicator(tabIndicator3);
th.addTab(specs);
th.addTab(specs2);
th.addTab(specs3);
of course replace R.drawable.ic_launcher with whatever icon you want to show
another interesting thing that might help..i notice if i pass in a blank for the title that the original way works but shows no title. So you could go into photoshop and just add the title to the image and make it even better looking. Try this way:
TabSpec specs = th.newTabSpec("Front");
specs.setContent(R.id.Front);
specs.setIndicator("",getResources().getDrawable(R.drawable.ic_launcher));
th.addTab(specs);
