Add foreground color and central icon to clickable view

I'm trying to achieve something like this!
Alternative to check box
How do I achieve this?
I tried creating a drawable with a central icon and a transparent background but the icon scales to fill the view when the drawable is set to the view foreground.
Also there is no support for setForground method for api level less than 23
I intend to achieve this dynamically when a view is clicked. Please help!!!

to achieve this view use relative layout like below code
<?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:gravity="center"
android:orientation="vertical">
<RelativeLayout
android:layout_width="90dp"
android:layout_height="120dp">
<ImageView
android:id="#+id/image_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/demo_img_4" />
<LinearLayout
android:id="#+id/transp_ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#30000000"
android:gravity="center">
<ImageView
android:id="#+id/delete_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_delete_black_24dp" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//initialize views
setContentView(R.layout.activity_main);
image_view = findViewById(R.id.image_view);
delete_btn = findViewById(R.id.delete_btn);
transp_ll = findViewById(R.id.transp_ll);
//set transparent layout visibility gone
transp_ll.setVisibility(View.GONE);
//set click listener
image_view.setOnClickListener(this);
delete_btn.setOnClickListener(this);
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.delete_btn:
//write here delete button click functionality..
transp_ll.setVisibility(View.GONE);
break;
case R.id.image_view:
transp_ll.setVisibility(View.VISIBLE);
break;
}
}

You should add a transparent view that matches the parent dimensions over you view and add a image view in center of it.
You can adjust your transparency level to get the desired effect

How to set the height and width of navIcon in ToolbarAndroid of react-native?

I am using navIcon of ToolbarAndroid to show the Icon in my react-native application as follows:
<ToolbarAndroid
actions={[]}
navIcon={require('./arrow-left-c.png')}
onIconClicked={navigator.pop}
style={{height:180,backgroundColor:'#a9a9a9'}}
titleColor="white"
title={route.name} />
But the problem is that the icon arrow-left-c is taking the whole width of screen. I only want to display it in the left side as normal icon appears. How can I set the width and height of this navIcon?

Currently you cannot set the size of navIcon in React native ToolBarAndroid.
Toolbar icon size should be 24dp as mentioned here.

I had same problem,and i solved it.
we know we need the icon with 24dp,and we need rename file name end up with #3X,
such as app_logo.png ===> app_logo#3x.png
you can found this at Images of RN

It will be a better option if u use seprate layout for toolbar and then inflate it in toolbar.In this layout you will be able to give any style size color and icon to it.
Take a new xml file app_bar layout and copy the following code in it.
<?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="?attr/actionBarSize"
android:background="#color/colorWhite">
<ImageView
android:id="#+id/btnBack"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:padding="10dp"
android:text="#string/back_font"
android:textColor="#color/colorBtn"
android:textSize="30sp" />
<TextView
android:id="#+id/lblTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_marginLeft="8dp"
android:layout_toRightOf="#+id/btnBack"
android:text="Create Account"
android:textColor="#color/colorBtn"
android:textSize="18sp" />
</RelativeLayout>
then in your activity containing toolbar copy this code.
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
final View barview =LayoutInflater.from(this).inflate(R.layout.app_bar_register, toolbar, false);
toolbar.addView(barview);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
ImageView btnBack= (ImageView) barview.findViewById(R.id.btnBack);
btnBack.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onBackPressed();
}
});

SherlockActionBar: How to adjust CustomView against actionBar

Question:
How can I have the title back?
Here's the screenshot (Missing title):
Actionbar setting:
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("My Title");
actionBar.setIcon(drawable.dropdown_user);
View mLogoView = LayoutInflater.from(this).inflate(R.layout.mLogoView, null);
actionBar.setCustomView(mLogoView);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setDisplayHomeAsUpEnabled(true);
mLogoView.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<ImageView
android:id="#+id/img_merchant"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="#drawable/infoflex">
</ImageView>
</RelativeLayout >

The first thing which I can think a way to fix that is try to set
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right" >
to your RelativeLayout. Because as default in Android every View is added from left to right (if you doesn't specify something else in your code).
And if that doesn't work, I would add android:layout_width="90dip" or some other value depending on the image and your tests. The second option is more like a workaround, but I think it will work on all devices.
Edit:
As I found there is a little problem using RelativeLayout and Custom Views in ActionBar, so the better option is to use LinearLayout and set LayoutParams via code. Change your xml to look like this :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/asus" />
</LinearLayout >
and in your MainActivity.class use this :
import com.actionbarsherlock.app.ActionBar.LayoutParams;
....
ActionBar actionBar = getSupportActionBar();
actionBar.setTitle("OMG");
LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.RIGHT | Gravity.CENTER_VERTICAL);
View customNav = LayoutInflater.from(this).inflate(R.layout.img, null); // layout which contains your button.
actionBar.setCustomView(customNav, lp);
actionBar.setDisplayShowCustomEnabled(true);

Android ABS center title with home button

I managed to center the title of the ABS using a custom view but the home button is gone. How can this be solved? Is the only way to do it to put this home button in the custom view? (To be clear: the home button should be on the left not in the center)
Custom view:
<?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:gravity="center"
android:background="#android:color/transparent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="hello"/>
</LinearLayout>
Activity code:
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
getSupportActionBar().setCustomView(R.layout.widget_actionbar_title);
getSupportActionBar().setHomeButtonEnabled(true);

getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
View customView = LayoutInflater.from(this).inflate(
R.layout.app_icon, null);
ActionBar.LayoutParams params = new ActionBar.LayoutParams(
ActionBar.LayoutParams.MATCH_PARENT,
ActionBar.LayoutParams.MATCH_PARENT, Gravity.CENTER);
getSupportActionBar().setCustomView(customView, params);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(getResources().getDrawable(R.drawable.back_button));

Add this:
getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM | ActionBar.DISPLAY_SHOW_HOME);

solution is very simple)
Change in your Layout
android:layout_width="match_parent"
on this:
android:layout_width="wrap_content"
it will help because your initial layout takes all visible place and there is no place for "home"

I had to add this code to make it work:
getSupportActionBar().setDisplayShowHomeEnabled(true);

Android action bar with two stretched buttons

Does anybody know how to easily implement an action bar with two stretched buttons?
Here is an example of the Google calendar app:
Thank you!

If you rather have this in the ActionBar for whatever reason, one way to achieve this is by using a custom view on the Action bar. Within you Custom View's layout then worry about setting up the buttons width.
Telling the activity to use a custom view for the action bar:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ActionBar ab = getActionBar();
ab.setDisplayShowHomeEnabled(false);
ab.setDisplayShowTitleEnabled(false);
final LayoutInflater inflater = (LayoutInflater)getSystemService("layout_inflater");
View view = inflater.inflate(R.layout.action_bar_edit_mode,null);
ab.setCustomView(view);
ab.setDisplayShowCustomEnabled(true);
}
layout/action_bar_edit_mode.xml can then look something like:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="fill_horizontal"
android:orientation="horizontal" >
<LinearLayout
android:layout_alignParentLeft="true"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<Button
android:id="#+id/action_bar_button_cancel"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Cancel" />
<Button
android:id="#+id/action_bar_button_ok"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:text="Ok" />
</LinearLayout>
</RelativeLayout>
Hope it helps someone!
Note: I realize the ugly nesting layouts here and normally I wouldn't recommend this but for some reason the actionbar's own layout refuses to let the LinearLayout take up the entire width on its own. Normally you should avoid nesting layouts unnecessarily like this!
Perhaps if someone sees this they can point us to a better solution?
What it looks like:
EDIT: There is an excellent post by Roman Nurik where he explains a way to do this very nicely.
EDIT 2: If anyone is curious, the correct way to lay out the buttons so that they expand the width of the actionbar without the need to nest your layouts like I did above, is to set the custom view with the proper layout parameters that allows its component to match the parent group.
Essentially:
actionBar.setCustomView(view,new ActionBar.LayoutParams(
ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));

I know 2 ways to do this, but one doesn't stay on top.
Here is the 1st:
You need to override the method onCreateOptionsMenu, but this is add on the ActionBar, you need API 11 to do this and when you rotate the screen this buttons appear on ActionBar, this depends of the screen size.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
MenuItem add = menu.add(Menu.NONE, ADD_TIME, 0, R.string.add_time);
add.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
MenuItem qkAdd = menu.add(Menu.NONE, QUICK_ADD_TIME, 1, R.string.quick_add_time);
qkAdd.setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
}
and this is the result:
if you're using a Fragment you need to set setHasOptionsMenu to true, otherwise the menu wont show.
Here is the 2nd:
cancel_done.xml
<?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:background="#color/color_bar"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:dividerPadding="12dp"
android:orientation="vertical"
android:showDividers="end" >
<Button
android:id="#+id/button1"
style="#drawable/btn_cab_done_holo_light"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="#drawable/btn_cab_done_holo_light"
android:text="CANCEL"
android:textSize="14sp" />
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:dividerPadding="12dp"
android:orientation="vertical"
android:showDividers="beginning" >
<Button
android:id="#+id/button2"
style="#drawable/btn_cab_done_holo_light"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="#drawable/btn_cab_done_holo_light"
android:text="DONE"
android:textSize="14sp" />
</LinearLayout>
</LinearLayout>
the resource style btn_cab_done_holo_light.xml you can find on ..\sdk\platforms\android-%%\data\res\drawable and then on your layout you just add:
<include
android:layout_width="match_parent"
android:layout_height="48dp"
android:layout_gravity="fill"
layout="#layout/cancel_done" />
and this is the result:
I don't now if is the best way, but it's working.

Make a horizontal LinearLayout with two buttons. Then set each of their widths to match_parent and android:layout_weight="0.5"
(Each button will then take up 50% of the space).
EDIT:
To apply as the ActionBar background:
(ActionBarSherlock) getSupportActionBar().setCustomView(R.layout.my_view);
(ActionBar) getActionBar().setCustomView(R.layout.my_view);

You can use the actionMode of the ActionBar to implement the Done and Cancel actions.
