Imagebutton以编程方式更改? [英] Imagebutton change programmatically?

问题描述

我正在尝试以编程方式更改ImageButton的图像.

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

我正在尝试复制此代码，但是setBackgroundDrawable已被弃用.

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);
}

我的按钮是使用xml创建的，如下所示:

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"/>

推荐答案

您的代码正在尝试更改按钮的背景.不是它的形象. 那是两件事

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);
