AddOnClick方法：

public void AddOnClick(View view){
    Intent intent = new Intent();
    intent.setClass(this, ActivityAdd.class);
    startActivity(intent);
    finish();

}

布局按钮：

<ImageButton
        android:id="@+id/buttonAdd"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/imageBig"
        android:layout_alignRight="@+id/imageBig"
        android:layout_marginBottom="@dimen/margin_button_add_top"
        android:layout_marginRight="@dimen/margin_button_add_left"
        android:background="@null"
        android:onClick="AddOnClick"
        android:src="@drawable/main_button_add" />

更正了完整的Manifest.xml

如果您使用外部jar，请确保将其导出到apk。你可以这样做 Go to Properties -> Java Build Path -> "Order and Export" 并检查所有导出的库
