Android ViewFlipper的使用（上下滚动）

Android ViewFlipper的使用（上下滚动）

private ViewFlipper mUPMarqueeView; //初始化
mUPMarqueeView =findViewById(R.id.view_flipper);

1， 在layout添加

<ViewFlipper
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/view_flipper"
    android:flipInterval="2500"
    android:layout_gravity="center"
    android:layout_marginLeft="8dp"
    android:layout_marginEnd="5dp"
    android:inAnimation="@anim/anim_marquee_in"
    android:outAnimation="@anim/anim_marquee_out"
    />

2，创建anim

anim_marquee_in

<translate android:duration="800" android:fromYDelta="100%p" android:toYDelta="0"/>

anim_marquee_out

<translate android:duration="800" android:fromYDelta="0" android:toYDelta="-100%p"/>

3，动态添加布局

for (int i = 0; i < bannerdata.size(); i = i + 2) {
    //设置滚动的单个布局
    LinearLayout moreView = (LinearLayout)
            LayoutInflater.from(this).inflate (R.layout.item_headline_advertisement, null);
    //初始化布局的控件
    TextView mTvTitle1 = moreView.findViewById(R.id.first_headline_content);
    TextView mTvTitle2 = moreView.findViewById(R.id.second_headline_content);
    //进行对控件赋值
    mTvTitle1.setText(bannerdata.get(i));
    //添加到循环滚动数组里面去
    mUPMarqueeView.addView(moreView);
}
mUPMarqueeView.startFlipping();
