概述
1.效果图
这也是产品要求达到的效果,于是才有了这个实现。
2.实现思路
总共就是7个按钮,中间的按钮然后被遮住的3个周报、日报、月报按钮,点击笔图标的按钮时,将被遮住的三个按钮移出,分别做左移、上移、右移100%的位置。给三个按钮添加动画监听事件,在onAnimationEnd方法里将按钮展开时,三个目标地点的按钮显示出来。
如图:
1)初始状态就是step1中那样,这里包含显示在最上层的按钮和被遮住的3个按钮。点击这个圆形按钮后,被遮住的按钮将启动定义好的动画开始移动,像step2那样。动画监听事件里有个表示动画结束的方法onAnimationEnd,在onAnimationEnd方法里将step3里面外围3个按钮setVisibility(View.VISIBLE)。这就是展开动画。
2)同理收拢的动画,是先隐藏外围三个按钮,然后启动动画。
3.核心代码
1)Activity
public class MainActivity extends Activity {
private ImageView imgWrite;
private TextView txtDaily, txtDailyShow, txtWeekly, txtWeeklyShow, txtMonthly, txtMonthlyShow;
private boolean isFold = true; // 卫星按钮展开状态
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
initUI(); // 初始化界面
initAnimation(); // 初始化动画
}
/**
* 初始化界面
*/
private void initUI() {
imgWrite = (ImageView) this.findViewById(R.id.daily_write_imageview);
txtDaily = (TextView) this.findViewById(R.id.daily_dialy_textview);

txtWeekly = (TextView) this.findViewById(R.id.daily_weekly_textview);
txtWeeklyShow = (TextView) this.findViewById(R.id.daily_weekly_show_textview);
txtMonthly = (TextView) this.findViewById(R.id.daily_monthly_textview);
txtMonthlyShow = (TextView) this.findViewById(R.id.daily_monthly_show_textview);
// 绑定事件
this.imgWrite.setOnClickListener(new OnClickListener() {
@Override

// 展开月报
