How to turn on one of the toggle buttons

I want the other toggle button to turn off when one turns on.
<item android:state_checked="true"
android:drawable="#drawable/press"></item>
<item android:drawable="#drawable/nomal"></item>
This is my togglebutton's xml code This code is made in 'drawable'.

You can use below selector as a background of the ToggleButton which picks the appropriate drawable when the button changes its check status
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ic_checked" android:state_checked="true" />
<item android:drawable="#drawable/ic_unchecked" android:state_checked="false" />
</selector>
and wrap both buttons in a RadioGroup; then traverse this group in a loop whenever a button is checked/clicked, and then negates those buttons with setChecked() method.
Layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<RadioGroup
android:id="#+id/toggleGroup"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="24dp"
android:orientation="horizontal">
<ToggleButton
android:id="#+id/toggle_btn_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/toggle_btn_selector"
android:onClick="onToggle"
android:textOff=""
android:textOn="" />
<ToggleButton
android:id="#+id/toggle_btn_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/toggle_btn_selector"
android:onClick="onToggle"
android:textOff=""
android:textOn="" />
</RadioGroup>
</LinearLayout>
Behavior
public class MainActivity extends AppCompatActivity {
RadioGroup mGroup;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGroup = findViewById(R.id.toggleGroup);
}
public void onToggle(View view) {
ToggleButton checkedBtn = ((ToggleButton) view);
for (int j = 0; j < mGroup.getChildCount(); j++) {
ToggleButton toggleButton = (ToggleButton) mGroup.getChildAt(j);
int id = toggleButton.getId();
if (view.getId() == id)
continue;
toggleButton.setChecked(!checkedBtn.isChecked());
}
}
}

You need to create RadioGroup, and add to it 2 RadioButtons with you drawable. Checkout second link, it will describes how to do it properly.
Also you need to change your drawable xml press to checked

Android: Switch with text and custom view

I need to develop a button like in this picture:
How can I customize Switch? Or if it is not possible, how to implement this custom view?

Try this
<Switch
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/toogle_switch"
android:text=""
android:textOn=""
android:textOff="" />
toogle_switch.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/on" android:state_checked="true"></item>
<item android:drawable="#drawable/off" android:state_checked="false"></item>
</selector>

<?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">
<Switch
android:id="#+id/switch1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:switchMinWidth="56dp"
android:layout_marginLeft="100dp"
android:layout_marginTop="120dp"
android:text="Switch1:"
android:checked="true"
android:textOff="OFF"
android:textOn="ON"/>
</RelativeLayout>
RelativeLayout layout = (RelativeLayout)findViewById(R.id.r_layout);
Switch sb = new Switch(this);
sb.setTextOff("OFF");
sb.setTextOn("ON");
sb.setChecked(true);
layout.addView(sb);
Switch sw = (Switch) findViewById(R.id.switch1);
sw.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
// The toggle is enabled
} else {
// The toggle is disabled
}
}
});

Highlight selected item on a gridview

I am trying to highlight a selected item on a gridview (dinamically populated with an adapter), but it is not working.
I did research and i even tried to copy exactly the selector of other people and even the way that they put it on the gridview but i am not being able to put it working.
It just doesn't do anything. The background of each item is white (like i wanted), but when i press it (it it is on top of a textview or a imageview (part of the gridview item) it doesn't do anything. If i press out of the imageView or textview, it will do what i want.
EDIT : I have listeners for the images and the textviews, so it might be interfering with this selector ? How could i solve this problem?
Here is the code of the activity where i create the gridview :
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.highway_appselection_activity);
gridView= (GridView) findViewById(R.id.HighwayGridView);
gridView.setSelector(new ColorDrawable(Color.BLACK));
Here is the xml of each item of this gridview : (where i define the background as the selector)
<?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:id="#+id/HighwayGridViewItem"
android:orientation="vertical"
android:background="#drawable/highway_appselection_selector"
android:padding="5dp">
<cm.aptoide.lite.HighwayCustomImageView
android:layout_width="72dp"
android:layout_height="72dp"
android:id="#+id/highwayGridViewItemIcon"
android:background="#FFFFFF"
android:layout_gravity="center"
android:scaleType="centerCrop"
android:padding="5dp"
android:clickable="true"/>
<!-- does this need to be my custom image view anymore? CHeck on that-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:id="#+id/highwayGridViewItemName"
android:textColor="#000000"
android:text="texto de teste"
android:textSize="10sp"
android:focusable="true"
android:ellipsize="marquee"
android:marqueeRepeatLimit="marquee_forever"
android:layout_weight="2"
android:textStyle="bold"
android:paddingRight="5dp"
android:layout_marginLeft="5dp"
android:clickable="true"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/info_icon"
android:padding="5dp"
android:clickable="true"
android:id="#+id/highwayGridViewItemInfoButton"/>
And here is my selector :
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:exitFadeDuration="#android:integer/config_mediumAnimTime">
<item android:state_enabled="true" android:state_pressed="true" android:drawable="#color/green_main_color" />
<item android:state_enabled="true" android:state_focused="true" android:drawable="#color/green_main_color" />
<item android:state_enabled="true" android:state_selected="true" android:drawable="#color/green_main_color" />
<item android:drawable="#android:color/white" />
I might be missing something, I am new to Android, sorry if there is any rookie mistake.

Create file selector.xml as:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/green_main_color" android:state_pressed="true"/>
<item android:drawable="#color/green_main_color" android:state_selected="true"/>
<item android:drawable="#color/white"/>
</selector>
Put your selector file in drawable folder as drawable/selector.xml and then in your gridView:
<GridView
android:id="#+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
android:listSelector="#drawable/list_selector"
android:scrollbars="none" />

try this :
int nPrevSelGridItem = -1;
gridview.setOnItemClickListener(new OnItemClickListener() {
View viewPrev;
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
try {
if (nPrevSelGridItem != -1) {
viewPrev = (View) gridview.getChildAt(nPrevSelGridItem);
viewPrev.setBackgroundColor(Color.WHITE);
}
nPrevSelGridItem = position;
if (nPrevSelGridItem == position) {
//View viewPrev = (View) gridview.getChildAt(nPrevSelGridItem);
view.setBackgroundColor(getResources().getColor(R.color.orange));
}
} catch (Exception e) {
e.printStackTrace();
}
}
});

How to Make LinearLayout Clickable

I have a linearlayout like this
<LinearLayout
android:id="#+id/optionlist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/divider"
android:orientation="vertical" >
</LinearLayout>
I want to add another xml view into this layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/option"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<!--
<View
android:layout_width="match_parent"
android:layout_height="0.5dip"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:background="#2fd275"
/>
-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:padding="10dp" >
<ImageView
android:id="#+id/option_image"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:src="#drawable/logout" />
<TextView
android:id="#+id/option_id"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#000000"
android:visibility="gone" />
<TextView
android:id="#+id/option_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_margin="10dp"
android:text="Signout"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#616161" />
</LinearLayout>
<View
android:id="#+id/divider"
android:layout_width="match_parent"
android:layout_height="0.5dip"
android:background="#d3d3d3" />
</LinearLayout>
via the code
for (int i = 0; i < opt.length; i++) {
View view = inflater.inflate(R.layout.option_item, optionlist,
false);
view.setBackgroundResource(R.drawable.optionlist);
view.setTag(opt_image[i]);
view.setClickable(true);
view.setFocusable(true);
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// ADD your action here
int res = (Integer) v.getTag();
switch (res) {
case R.drawable.logout:
signout();
break;
}
}
});
final TextView tv = (TextView) view.findViewById(R.id.option_name);
final ImageView iv = (ImageView) view
.findViewById(R.id.option_image);
tv.setText(opt[i]);
iv.setImageResource(opt_image[i]);
optionlist.addView(view);
}
Now on click of the layout i want to load this xml file as below...but i am not able to get the backgroud loaded on the click event. Please give suggestion what am I doing wrong?
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#color/holo_green_dark" android:state_focused="true"/>
<item android:drawable="#color/holo_green_dark" android:state_enabled="false" android:state_pressed="true"/>
<item android:drawable="#color/white"/>
</selector>

First get id of LinearLayout from xml and then perform onClickListener on it instead of whole View
View view = inflater.inflate(R.layout.option_item, optionlist, false);
LinearLayout layout = view.findViewByIt(R.id.optionlist);
layout.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// ADD your action here
int res=(Integer) v.getTag();
switch(res)
{
case R.drawable.logout: signout();
break;
}
}
});

try this.. hope it works..
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#ff0000" />//ur onclick desired color
<item android:state_focused="false"
android:drawable="#android:color/transparent" />focused color
</selector>
just create new xml and add this code in drawable and set ur linear layoyut backgrout as its name like android:background="#drawable/createdxmlname"
<LinearLayout
android:id="#+id/optionlist"
android:layout_below="#id/divider"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/createdxmlname"
android:clickable="true">

android:clickable="false"
<LinearLayout
android:id="#+id/parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<ImageButton
android:clickable="false"
android:layout_width="40dp"
android:layout_height="40dp"
android:text="Cinema"
android:textSize="13sp"
android:layout_marginRight="10dp" />
<Button
android:clickable="false"
android:layout_width="match_parent"
android:layout_height="40dp"
android:text="Check in"
android:textSize="13sp" />
</LinearLayout>

Create in drawable an pressed_layout.xml with the following content
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
android:drawable="#drawable/button_pressed" /> <!-- pressed -->
<item android:state_focused="true"
android:drawable="#drawable/button_focused" /> <!-- focused -->
<item android:drawable="#drawable/button_normal" /> <!-- default -->
</selector>
And in your layout add it as background resource:
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:background="#drawable/pressed_layout"
android:clickable="true">
</LinearLayout>

layout.setclickble="true" in XML file and
layout.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(View arg0) {
// TODO Auto-generated method stub
}
});

We can also use onClick in XML of layout,and use that method in java file,like if onClick="next",then in java file we have to use the method .
public void next()
{
// do something
}

Button Selected State Android?

I am developing an application which consists of button.
Here Is My problem,how to set the selected state and unselected state.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/ox_mnu_dashboard_over" android:state_selected="true"/>
<item android:drawable="#drawable/ox_mnu_dashboard_normal"/>
</selector>
I am using this code but not working for me.
Here is the xml file:
<FrameLayout
android:id="#+id/tabDashboard"
android:layout_width="60dip"
android:layout_height="wrap_content"
android:layout_marginLeft="2dip"
android:layout_weight="1"
android:clickable="true" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal"
android:focusableInTouchMode="true"
android:marqueeRepeatLimit="marquee_forever"
android:scrollHorizontally="true"
android:singleLine="true"
android:text="#string/dashboard"
android:textColor="#color/white"
android:textSize="12sp" />
<ImageButton
android:id="#+id/btnDashboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/tab_dashboard"
android:clickable="true" />
</FrameLayout>

You can set image when click on that imageButton like below code.
int isClicked = 0;
image = (ImageButton) findViewById(R.id.image);
image.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (isClicked1 == 0) {
image.setImageResource(R.drawable.second_image);
isClicked1 = 1;
} else {
image.setImageResource(R.drawable.original_image);
isClicked1 = 0;
}
}
});'
