使用longclick更改imagebutton图像（从图库）

Question

I've searched the forums, but not have found any specific or understandable answers for my problem.

I'd like to change my Imagebutton image to a picture, selected from the gallery. Prefferrably the image should stay changed after closing the application.

My XML for the button is here:

<ImageButton
        android:id="@+id/eat"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:adjustViewBounds="true"
        android:background="@drawable/eat"
        android:clickable="true"
        android:longClickable="true"
        android:scaleType="fitCenter" />

The java code for playing the sound is here with the OnClick method.

    ImageButton eat = (ImageButton) findViewById (R.id.eat);
    eat.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mp1.start();
        }
    });

I would like to add the OnLongClick method here too, (since to OnClick is allready taken and the image replacing should be a little different), but havent found the right way. Can You please guide me a little bit?

Answer 1

You need to return true from image's onLongClickListener.

Like this:

eat.setOnLongClickListener(new OnLongClickListener() {

    @Override
    public boolean onLongClick(View v) {
        //do something
        return true;
    }

});

eat.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        mp1.start();
    }
});

This will not cause the image's onClickListener to be called as it means that the action has already been handled in longClickListener.
