android - 强制关闭ImageButton的onClick，无法弄清楚为什么

Question

我正在尝试使用 ImageButtons 做一个简单的动画，当我设置它时，如果我只是触摸屏幕，它工作得很好，但如果我尝试在点击时做，应用程序就会关闭。

主.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>

翻译.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>

主要 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

框架找不到您的点击处理程序方法，因为它的签名有误。像这样声明:

public void RunAnimations(View view) {
    . . .
}
