Force close onClick of ImageButton, can't figure out why
I'm trying to do a simple animation with ImageButtons, when I set it up so that if I simply touch the screen, it works just fine, but if I try to do it onClick, the app just closes.
Main.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal">
<ImageButton
android:id="@+id/plus1"
android:layout_width="75dp"
android:layout_height="75dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:background="@null"
android:src="@drawable/plus"
android:visibility="visible"
android:gravity="center_horizontal"
android:onClick="RunAnimations"
/>
<ImageButton
android:id="@+id/gears1"
android:layout_width="75dp"
android:layout_height="75dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:background="@null"
android:gravity="center_horizontal"
android:src="@drawable/gears"
android:textSize="42sp" />
</LinearLayout>
translate.xml
<?xml version="1.0" encoding="utf-8"?>
<set>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromYDelta="-100%"
android:toYDelta="0%"
android:duration="1000"
android:zAdjustment="top" >
</translate>
<alpha
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:duration="1000">
</alpha>
</set>
The main Activity:
public class AnimationtestActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
private void RunAnimations() {
Animation a = AnimationUtils.loadAnimation(this, R.anim.translate);
View ib = findViewById(R.id.gears1);
ib.clearAnimation();
ib.startAnimation(a);
}
}
edit:
I fixed the private void RunAnimations(View view)
But it's still force closing

The framework isn't finding your click handler method because it has the wrong signature. Declare it like this:
public void RunAnimations(View view) {
. . .
}
