android imageview - How to center icon and text in a android button with width set to “fill parent”




13 Answers

android:drawableLeft is always keeping android:paddingLeft as a distance from the left border. When the button is not set to android:width="wrap_content", it will always hang to the left!

With Android 4.0 (API level 14) you can use android:drawableStart attribute to place a drawable at the start of the text. The only backward compatible solution I've come up with is using an ImageSpan to create a Text+Image Spannable:

Button button = (Button) findViewById(R.id.button);
Spannable buttonLabel = new SpannableString(" Button Text");
buttonLabel.setSpan(new ImageSpan(getApplicationContext(), R.drawable.icon,      
    ImageSpan.ALIGN_BOTTOM), 0, 1, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
button.setText(buttonLabel);

In my case I needed to also adjust the android:gravity attribute of the Button to make it look centered:

<Button
  android:id="@+id/button"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:minHeight="32dp"
  android:minWidth="150dp"
  android:gravity="center_horizontal|top" />
bottom drawable

I want to have an Android Button with icon+text centered inside it. I'm using the drawableLeft attribute to set the image, this works well if the button has a width of "wrap_content" but I need to stretch to max width so I use width "fill_parent". This moves my icon straight to the left of the button and I want both icon and text centered inside the button.

I've try setting up the padding but this only allows to give a fixed value so it is not what I need. I need to have icon+text aligned in the center.

<Button 
    android:id="@+id/startTelemoteButton" 
    android:text="@string/start_telemote"
    android:drawableLeft="@drawable/start"
    android:paddingLeft="20dip"
    android:paddingRight="20dip"            
    android:width="fill_parent"
    android:heigh="wrap_content" />

Any suggestions on how I could achieve that?




I used LinearLayout instead of Button. The OnClickListener, which I need to use works fine also for LinearLayout.

<LinearLayout
    android:id="@+id/my_button"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/selector"
    android:gravity="center"
    android:orientation="horizontal"
    android:clickable="true">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="15dp"
        android:adjustViewBounds="true"
        android:scaleType="fitCenter"
        android:src="@drawable/icon" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Text" />

</LinearLayout>



I recently bumped into the same problem. Tried to find a cheaper solution so came up with this.

   <LinearLayout
        android:id="@+id/linearButton"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/selector_button_translucent_ab_color"
        android:clickable="true"
        android:descendantFocusability="blocksDescendants"
        android:gravity="center"
        android:orientation="horizontal" >

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:contentDescription="@string/app_name"
            android:src="@drawable/ic_launcher" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/app_name"
            android:textColor="@android:color/white" />
    </LinearLayout>

Then just call the OnClickListener on LinearLayout.

Hope this helps someone as it seems like a very common problem. :)




My way of solving it involved surrounding the the button with lightweight <View ../> elements that resize dynamically. Below are several examples of what can be achieved with this:

Note that the clickable area of the buttons in example 3 is the same as in 2 (i.e. with spaces), which is different from example 4 where there are no "unclickable" gaps in between.

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:orientation="vertical">
    <TextView
        android:layout_marginStart="5dp"
        android:layout_marginLeft="5dp"
        android:layout_marginTop="10dp"
        android:layout_marginBottom="5dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textStyle="bold"
        android:text="Example 1: Button with a background color:"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"/>
        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Button"
            android:textColor="@android:color/white"
            android:drawableLeft="@android:drawable/ic_secure"
            android:drawableStart="@android:drawable/ic_secure"
            android:background="@android:color/darker_gray"
            android:paddingStart="20dp"
            android:paddingEnd="20dp"
            android:layout_weight="0.3"/>
        <!-- Play around with the above 3 values to modify the clickable 
             area and image alignment with respect to text -->
        <View
            android:layout_width="0dp"

You can create a custom widget:

The Java class IButton:

public class IButton extends RelativeLayout {

private RelativeLayout layout;
private ImageView image;
private TextView text;

public IButton(Context context) {
    this(context, null);
}

public IButton(Context context, AttributeSet attrs) {
    this(context, attrs, 0);
}

public IButton(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);

    LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view = inflater.inflate(R.layout.ibutton, this, true);

    layout = (RelativeLayout) view.findViewById(R.id.btn_layout);

    image = (ImageView) view.findViewById(R.id.btn_icon);
    text = (TextView) view.findViewById(R.id.btn_text);

    if (attrs != null) {
        TypedArray attributes = context.obtainStyledAttributes(attrs,R.styleable.IButtonStyle);

        Drawable drawable = attributes.getDrawable(R.styleable.IButtonStyle_button_icon);
        if(drawable != null) {
            image.setImageDrawable(drawable);
        }

        String str = attributes.getString(R.styleable.IButtonStyle_button_text);
        text.setText(str);

        attributes.recycle();
    }

}

@Override
public void setOnClickListener(final OnClickListener l) {
    super.setOnClickListener(l);
    layout.setOnClickListener(l);
}

public void setDrawable(int resId) {
    image.setImageResource(resId);
}

}

The layout ibutton.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/btn_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true" >

<ImageView
    android:id="@+id/btn_icon"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_marginRight="2dp"
    android:layout_toLeftOf="@+id/btn_text"
    android:duplicateParentState="true" />

<TextView
    android:id="@+id/btn_text"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:layout_centerInParent="true"
    android:duplicateParentState="true"
    android:gravity="center_vertical"
    android:textColor="#000000" />
</RelativeLayout>

In order to use this custom widget:

<com.test.android.widgets.IButton
     android:id="@+id/new"
     android:layout_width="fill_parent"         
     android:layout_height="@dimen/button_height"
     ibutton:button_text="@string/btn_new"
     ibutton:button_icon="@drawable/ic_action_new" />

You have to provide the namespace for the custom attributes xmlns:ibutton="http://schemas.android.com/apk/res/com.test.android.xxx" where com.test.android.xxx is the root package of the application.

Just put it below xmlns:android="http://schemas.android.com/apk/res/android".

The last thing you gonna need are the custom attributes in the attrs.xml.

In the attrs.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <declare-styleable name="IButtonStyle">
        <attr name="button_text" />
        <attr name="button_icon" format="integer" />
    </declare-styleable>

    <attr name="button_text" />

</resources>

For better positioning, wrap the custom Button inside a LinearLayout, if you want to avoid potential problems with RelativeLayout positionings.

Enjoy!




<style name="captionOnly">
    <item name="android:background">@null</item>
    <item name="android:clickable">false</item>
    <item name="android:focusable">false</item>
    <item name="android:minHeight">0dp</item>
    <item name="android:minWidth">0dp</item>
</style>

<FrameLayout
   style="?android:attr/buttonStyle"
   android:layout_width="match_parent"
   android:layout_height="wrap_content" >

    <Button
       style="@style/captionOnly"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_gravity="center"
       android:drawableLeft="@android:drawable/ic_delete"
       android:gravity="center"
       android:text="Button Challenge" />
</FrameLayout>

Put the FrameLayout in LinearLayout and set orientation to Horizontal.







I think android:gravity= "centre" should work







Dirty fix.

android:paddingTop="10dp"
android:drawableTop="@drawable/ic_src"

Figuring right padding solve the purpose. However, for varied screen, use different padding and put that in dimens resource in respective value folder.




Other possibility to keep Button theme.

<Button
            android:id="@+id/pf_bt_edit"
            android:layout_height="@dimen/standard_height"
            android:layout_width="match_parent"
            />

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_alignBottom="@id/pf_bt_edit"
            android:layout_alignLeft="@id/pf_bt_edit"
            android:layout_alignRight="@id/pf_bt_edit"
            android:layout_alignTop="@id/pf_bt_edit"
            android:layout_margin="@dimen/margin_10"
            android:clickable="false"
            android:elevation="20dp"
            android:gravity="center"
            android:orientation="horizontal"
            >

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:adjustViewBounds="true"
                android:clickable="false"
                android:src="@drawable/ic_edit_white_48dp"/>

            <TextView
                android:id="@+id/pf_tv_edit"
                android:layout_width="wrap_content"
                android:layout_height="match_parent"
                android:layout_marginLeft="@dimen/margin_5"
                android:clickable="false"
                android:gravity="center"
                android:text="@string/pf_bt_edit"/>

        </LinearLayout>

With this solution if your add @color/your_color @color/your_highlight_color in your activity theme, you can have Matherial theme on Lollipop whith shadow and ripple, and for previous version flat button with your color and highlight coor when you press it.

Moreover, with this solution autoresize of picture

Result : First on Lollipop device Second : On pre lollipop device 3th : Pre lollipop device press button




This may be an old/closed thread but I've search everywhere didnt find something useful, until I decided to create my own solution. If theres anyone here trying to look for answer try this one, might save you a minute of thinking

          <LinearLayout
            android:id="@+id/llContainer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@drawable/selector"
            android:clickable="true"
            android:gravity="center"
            android:orientation="vertical"
            android:padding="10dp"
            android:textStyle="bold">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:text="This is a text" />

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/icon_image />


        </LinearLayout>

Because Linear layout act as the container and the one who has the selector, when you click the entire linear layout it would look just how it should it be. if you want it to be both centered, use relative insteaf. If you want it centered horizontally change the orientation to horizontal.

Take note DO NOT forget to add android:clickable="true" to your main container (relative or linear) for the action to take place.

Again this may be old thread but may still help someone there.

-cheers hope it helps- happycodings.




use this android:background="@drawable/ic_play_arrow_black_24dp"

just set the background to the icon you want to center
