How to show the text on a ImageButton?

问题:

I have an ImageButton and I want to show a text and an image on it. But when I try on emulator:

<ImageButton 
    android:text="OK" 
    android:id="@+id/buttonok" 
    android:src="@drawable/buttonok"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" />

I get the image but without the text. How can I show the text? Please help me!

回答1:

As you can't use android:text I recommend you to use a normal button and use one of the compound drawables. For instance:

<Button 
    android:id="@+id/buttonok" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:drawableLeft="@drawable/buttonok"
    android:text="OK"/>

You can put the drawable wherever you want by using: drawableTop, drawableBottom, drawableLeft or drawableRight.

UPDATE

For a button this too works pretty fine. Putting android:background is fine!

<Button
    android:id="@+id/fragment_left_menu_login"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/button_bg"
    android:text="@string/login_string" />

I just had this issue and is working perfectly.

It is technically possible to put a caption on an ImageButton if you really want to do it. Just put a TextView over the ImageButton using FrameLayout. Just remember to not make the Textview clickable.

Example:

<FrameLayout>
    <ImageButton
        android:id="@+id/button_x"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@null"
        android:scaleType="fitXY"
        android:src="@drawable/button_graphic" >
    </ImageButton>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:clickable="false"
        android:text="TEST TEST" >
    </TextView>
</FrameLayout>

Actually, android:text is not an argument accepted by ImageButton but, If you're trying to get a button with a specified background (not android default) use the android:background xml attribute, or declare it from the class with .setBackground();

You can use a LinearLayout instead of using Button it's an arrangement i used in my app

 <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="20dp"
        android:background="@color/mainColor"
        android:orientation="horizontal"
        android:padding="10dp">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="@drawable/ic_cv"
            android:textColor="@color/offBack"
            android:textSize="20dp" />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:text="@string/cartyCv"
            android:textColor="@color/offBack"
            android:textSize="25dp" />

    </LinearLayout>

Guys I need to develop the setting and logout button, I used the below code.

    <Button
        android:id="@+id/imageViewLogout"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/size_30dp"
        android:layout_alignParentLeft="true"
        android:text="Settings"
        android:drawablePadding="10dp"
        android:background="@android:color/transparent"
        android:layout_alignParentBottom="true"
        android:drawableTop="@drawable/logout" />

回答6:

you can use a regular Button and the android:drawableTop attribute (or left, right, bottom) instead.

回答7:

Best way:

<Button 
android:text="OK" 
android:id="@+id/buttonok" 
android:background="@drawable/buttonok"
android:layout_width="match_parent" 
android:layout_height="wrap_content"/>

I solved this by putting the ImageButton and TextView inside a LinearLayout with vertical orientation. Works great!

<LinearLayout
    android:id="@+id/linLayout"
    android:layout_width="80dp"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ImageButton
        android:id="@+id/camera_ibtn"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_gravity="center"
        android:background="@drawable/camera" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="80dp"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="@string/take_pic"
        android:textColor="#FFFFFF"
        android:textStyle="bold" />

</LinearLayout>

Heres a nice circle example:

drawable/circle.xml:

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">

    <solid
        android:color="#ff87cefa"/>

    <size
        android:width="60dp"
        android:height="60dp"/>
</shape>

And then the button in your xml file:

<Button
    android:id="@+id/btn_send"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:background="@drawable/circle"
    android:text="OK"/>

回答10:

ImageButton can't have text (or, at least, android:text isn't listed in its attributes).

The Trick is:

It looks like you need to use Button (and look at drawableTop or setCompoundDrawablesWithIntrinsicBounds(int,int,int,int)).
