Imagebutton change programmatically?

问题

I'm trying to change the image of the ImageButton programmatically.

I'm trying to copy this code, but the setBackgroundDrawable is already deprecated.

public void giveClue(View view) {
    Drawable replacer = getResources().getDrawable(R.drawable.icon2);
    ((ImageButton) view).setEnabled(false);
    ((ImageButton) view).setBackgroundDrawable(replacer);
    gameAdapter.giveClue(game);
}

My button was created using xml as follows:

   <ImageButton
        android:id="@+id/ImageButton2"
        android:layout_width="24dp"
        android:layout_height="22dp"
        android:layout_alignTop="@+id/imageButton1"
        android:layout_toLeftOf="@+id/ImageButton3"
        android:src="@drawable/icon" 
        android:onClick="giveClue"/>

Please help.

Thank you.

回答1:

your code is trying to change the background of the button. not its image. Those are two different things

  ((ImageButton) view).setImageResource(R.drawable.icon2);

回答2:

Try this its working for me,Change the background image programmatically,

 image.setBackgroundResource(R.drawable.ico);

Hi you can use the following code

if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN ) 
{
    ((ImageButton) view).setImageResource(getResources().getIdentifier("icon2", "drawable", getPackageName()));
}
else 
{
    ((ImageButton) view).setImageDrawable(getDrawable(getResources().getIdentifier("icon2", "drawable", getPackageName())));
}

Hope this will help you.

Just try out this way:

((ImageButton) view).setImageDrawable(replacer);

回答5:

Using Kotlin, you can do this:

val myImageButton = ImageButton(context).apply({
    background = null
    setImageDrawable(ContextCompat.getDrawable(context, 
                         R.drawable.ic_save_black_24px))
})

For kotlin this works for me

yourimagebuttonID.setImageResource(R.drawable.ic_check_black_24dp)

回答7:

Try ((ImageButton) view).setImageDrawable(replacer);
