How To Toggle Background Image On Button Click?

I have this code: button1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub button1.setB

Solution 1:

you can take a variable

int i=0;

it will increase with every click.

if(i%2==0)
   setone image
elseset another image

Solution 2:

How about creating an array of the drawable's IDs and saving an index:

privatefinalint[] myDrawables = {R.drawable.detailpressed, R.drawable.detailpressed1, ...};
//...
button1.setOnClickListener(newOnClickListener() {
    intindex=0;
    @OverridepublicvoidonClick(View v) {
        button1.setBackgroundResource(myDrawables[index++ % myDrawables.length]);
        Chapter_sync.add(chapid);
    }
}

Solution 3:

declare variable as

booleanisOddClicked=true;

And update your click listener as

button1.setOnClickListener(newOnClickListener() {
        @OverridepublicvoidonClick(View v) {
            // TODO Auto-generated method stub//Do stuff here for chnaging background of buttonif(isOddClicked) {
                button1.setBackgroundResource(R.drawable.detailpressed);
                isOddClicked = false;
            } else {
                button1.setBackgroundResource(R.drawable.detailpressed_SECOND_IMAGE);
                isOddClicked = true;
            }

            //Do your taskChapter_sync.add(chapid);
        }

NOTE: If your requirement moves between two images then you can use toggle button and customize it. It will work for same as your requirement.

Solution 4:

if xml as the following

<code><Buttonandroid:id="@+id/btnListView"android:layout_width="35dp"android:layout_height="35dp"android:background="@drawable/list_view"android:onClick="switchToListView"android:visibility="visible"
            /><Buttonandroid:id="@+id/btnGridView"android:layout_width="35dp"android:layout_height="35dp"android:background="@drawable/grid_view"android:onClick="switchToGridView"android:visibility="gone"
            /><code>

---

handling Code will be like

<code>
publicvoidswitchToListView(View view) {
    (Button) findViewById(R.id.btnListView).setVisibility(View.GONE);
    (Button) findViewById(R.id.btnGridView).setVisibility(View.VISIBLE);
}
publicvoidswitchToGridView(View view) {
    (Button) findViewById(R.id.btnGridView).setVisibility(View.GONE);
    (Button) findViewById(R.id.btnListView).setVisibility(View.VISIBLE);

}
