文字垂直轮播翻页

在layout布局文件中声明TextSwitcher

位移的动画

inAnimation的动画,outAnimation的动画修改fromYDelta的值即可

添加TextSwitcher的主体内容

TextSwitcher.setFactory(new ViewSwitcher.ViewFactory() {
            //这里 用来创建内部的视图，这里创建TextView，用来显示文字
            @Override
            public View makeView() {
                final TextView tv = new TextView(getContext());
                //设置文字大小
                tv.setTextSize(UIUtils.dip2px(15));
                //设置文字 颜色
                tv.setTextColor(Color.BLACK);
                tv.setSingleLine();
                tv.setEllipsize(TextUtils.TruncateAt.END);
                FrameLayout.LayoutParams lp = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
                lp.gravity = Gravity.CENTER;
                tv.setLayoutParams(lp);
                //内容的点击事件
                tv.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        ToastUtils.showToast(tv.getText().toString());
                    }
                });
                return tv;
            }
        });

Handler设置循环

Handler handler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what){
                case NEWS_MESSAGE_TEXTVIEW:
                    index++;
                    TextSwitcher.setText(mStrings.get(index%mStrings.size()));
                    if (index == mStrings.size()) {
                        index = 0;
                    }
                    //3秒循环一次
                    handler.sendEmptyMessageDelayed(NEWS_MESSAGE_TEXTVIEW,3000);  
                    break;
                default:
                    break;
            }
        }
    };
..........................
//3秒后启动循环
handler.sendEmptyMessageDelayed(NEWS_MESSAGE_TEXTVIEW,3000);
