之前的自定义控件——初识自定义控件,我们了解到了自定义控件分为三种,自制控件,组合控件,拓展控件。
而我们在自制控件1 开关按钮自制控件2 —— 自制控件 仿qq侧滑菜单
在组合控件1—— 设置框一文中,我们也对设置框(组合控件)完成了demo编写
接下来,还是进行组合控件的编写。
先准备一个项目xml布局文件
后把这个xml填充进当前的自定义控件

接下来我们来做一个简单的缩放动画,从展开状态,切换到只显示最中间一个ImageView的状态。
我们这里采用属性动画做,为了让动画缩放过程明显,我们播放动画的时间设定为2000毫秒。(原生自带android3.0以才可以使用属性动画,有兴趣的可以切换为补间动画或者采用开源库)
附上代码:
public class OpExpandView extends RelativeLayout implements View.OnClickListener {
private RelativeLayout mRlOut;
private ImageView mIvcCenter;
public OpExpandView(Context context) {
super(context);
initUI(context);
}
public OpExpandView(Context context, AttributeSet attrs) {

}

super(context, attrs, defStyleAttr);
initUI(context);
}

View.inflate(context, R.layout.diy_op_view,this);
// 因为父视图是this,也就是OpExpandView,所以直接findViewById
mRlOut = (RelativeLayout) findViewById(R.id.mRlOut);
mIvcCenter = (ImageView) findViewById(R.id.mIvcCenter);
mIvcCenter.setOnClickListener(this);
}
@Override
public void onClick(View v) {
switch (v.getId()){
// 点击中间的ImageView
case R.id.mIvcCenter:
scaleGeneral(mIvcCenter,2000,"scaleX",1.0f,0.0f);
scaleGeneral(mIvcCenter,2000,"scaleY",1.0f,0.0f);
