Android仿直播类app赠送礼物功能

直播界面

实现的是播放本地的视频文件：

/**
 * 直播界面，用于对接直播功能
 */
public class LiveFrag extends Fragment {

 private ImageView img_thumb;
 private VideoView video_view;

 @Nullable
 @Override
 public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
 View view = inflater.inflate(R.layout.frag_live, null);
 img_thumb = view.findViewById(R.id.img_thumb);
 img_thumb.setVisibility(View.GONE);
 video_view = view.findViewById(R.id.video_view);
 video_view.setVisibility(View.VISIBLE);
 video_view.setVideoURI(Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.video_1));
 video_view.start();
 video_view.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
 @Override
 public void onCompletion(MediaPlayer mp) {
 video_view.setVideoURI(Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.video_1));
 //或 //mVideoView.setVideoPath(Uri.parse(_filePath));
 video_view.start();
 }
 });
 return view;
 }
}

布局文件 frag_live.xml 如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical">
 <VideoView
 android:id="@+id/video_view"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:clickable="false"
 android:focusable="false"
 android:visibility="gone" />
 <ImageView
 android:id="@+id/img_thumb"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:clickable="false"
 android:focusable="false"
 android:scaleType="centerCrop"
 android:src="@mipmap/img_video_1"
 android:visibility="visible" />
</LinearLayout>

滑动隐藏效果

需要实现的效果如下：

自定义DialogFragment，使用ViewPager，第一个为空的Fragment，第二个为我们需要的Fragment，左右滑动来切换显示和隐藏效果。

观众功能交互页面 InteractiveFrag 如下:

/**
 * 观众功能交互页面, 滑动隐藏效果
 */
public class InteractiveFrag extends DialogFragment {

 public View view;
 public Context myContext;
 private ViewPager vp_interactive;
 private LayerFrag layerFrag;

 @Override
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
 view = inflater.inflate(R.layout.frag_interactive, null);
 // 初始化
 initView();
 initData();
 return view;
 }

 /**
 * 初始化View
 */
 public void initView() {
 vp_interactive = view.findViewById(R.id.vp_interactive);
 }

 /**
 * 初始化数据
 */
 public void initData() {
 // EmptyFrag：什么都没有
 // LayerFrag：交互界面
 // 这样就达到了滑动隐藏交互的需求
 vp_interactive.setAdapter(new FragmentPagerAdapter(getChildFragmentManager()) {
 @Override
 public int getCount() {
 return 2;
 }

 @Override
 public Fragment getItem(int position) {
 if (position == 0) {
 return new EmptyFrag(); // 返回空界面的fragment
 } else if (position == 1) {
 return layerFrag = new LayerFrag(); // 返回交互界面的frag
 } else { // 设置默认

 return new EmptyFrag();
 }
 }
 });
 // 设置默认显示交互界面
 vp_interactive.setCurrentItem(1);

 // 同时将界面改为resize已达到软键盘弹出时Fragment不会跟随移动
 getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
 }

 @Override
 public Dialog onCreateDialog(Bundle savedInstanceState) {

 // 设置DialogFragment的样式，这里的代码最好还是用我的，大家不要改动
 Dialog dialog = new Dialog(getActivity(), R.style.MainDialog) {

 @Override
 public void onBackPressed() {
 super.onBackPressed();
 getActivity().finish();
 }
 };
 return dialog;
 }
}

frag_interactive.xml文件如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent"

EmptyFrag：

/**

 */
public class EmptyFrag extends Fragment {
 @Nullable
 @Override
 public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
 return inflater.inflate(R.layout.frag_empty, null);
 }
}

 android:layout_width="match_parent"
 android:layout_height="match_parent"

在MainActivity中使用FrameLayout布局，将观众功能交互页面 InteractiveFrag 覆盖在 直播页面LiveFrag上面。

MainActivity:

public class MainActivity extends AppCompatActivity {

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 // 加载直播fragment
 LiveFrag liveFrag = new LiveFrag();
 getSupportFragmentManager().beginTransaction().add(R.id.fl_root, liveFrag).commit();
 // 加载
 new InteractiveFrag().show(getSupportFragmentManager(), "InteractiveFrag");
 }
}

activity_main.xml :

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent"
 android:layout_height="match_parent">
 <FrameLayout
 android:id="@+id/fl_root"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />
</RelativeLayout>

用户交互页实现

MagicTextView动画效果

MagicTextView代码在文章最后展示。

我们先实现如下动画效果

<com.hongx.zhibo.utils.MagicTextView
 android:id="@+id/mtv_giftNum"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:layout_centerVertical="true"
 android:layout_marginLeft="5dp"
 android:layout_toRightOf="@+id/rlparent"
 android:includeFontPadding="false"
 android:text="x1"
 android:textColor="@android:color/holo_red_dark"
 android:textSize="30sp"
 android:textStyle="bold"
 app:strokeColor="@android:color/white"
 app:strokeJoinStyle="miter"
 app:strokeWidth="2" />

动画：

 public class NumberAnim {
 private Animator lastAnimator;
 public void showAnimator(View v) {
 if (lastAnimator != null) {
 lastAnimator.removeAllListeners();
 lastAnimator.cancel();
 lastAnimator.end();
 }
 ObjectAnimator animScaleX = ObjectAnimator.ofFloat(v, "scaleX", 1.3f, 1.0f);
 ObjectAnimator animScaleY = ObjectAnimator.ofFloat(v, "scaleY", 1.3f, 1.0f);
 AnimatorSet animSet = new AnimatorSet();
 animSet.playTogether(animScaleX, animScaleY);
 animSet.setDuration(200);
 lastAnimator = animSet;
 animSet.start();
 }
 }

 mtv_giftNum.setText("x" + count);
 giftNumberAnim = new NumberAnim(); // 初始化数字动画
 mtv_giftNum.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View v) {
 count++;
 mtv_giftNum.setText("x" + count);
 giftNumberAnim.showAnimator(mtv_giftNum);
 }
 });

礼物进入时动画

进入动画设置为decelerate_interpolator减速插值器：

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
 android:duration="500"
 android:fromXDelta="-100%p"
 android:interpolator="@android:anim/decelerate_interpolator"
 android:toYDelta="0%p">
</translate>

 /**
 * 刷礼物的方法
 */
 private void showGift(String tag) {
 View newGiftView = ll_gift_group.findViewWithTag(tag);
 // 是否有该tag类型的礼物
 if (newGiftView == null) {
 // 获取礼物
 newGiftView = getNewGiftView(tag);
 ll_gift_group.addView(newGiftView);

 // 播放动画
 newGiftView.startAnimation(inAnim);
 final MagicTextView mtv_giftNum = newGiftView.findViewById(R.id.mtv_giftNum);
 inAnim.setAnimationListener(new Animation.AnimationListener() {

 @Override
 public void onAnimationStart(Animation animation) {
 }

 @Override
 public void onAnimationRepeat(Animation animation) {
 }

 @Override
 public void onAnimationEnd(Animation animation) {
 giftNumberAnim.showAnimator(mtv_giftNum);
 }
 });
 } else {
 // 如果列表中已经有了该类型的礼物，则不再新建，直接拿出
 // 更新标识，记录最新修改的时间，用于回收判断
 ImageView iv_gift = newGiftView.findViewById(R.id.iv_gift);
 iv_gift.setTag(System.currentTimeMillis());

 // 更新标识，更新记录礼物个数
 MagicTextView mtv_giftNum = newGiftView.findViewById(R.id.mtv_giftNum);
 int giftCount = (int) mtv_giftNum.getTag() + 1; // 递增
 mtv_giftNum.setText("x" + giftCount);
 mtv_giftNum.setTag(giftCount);
 giftNumberAnim.showAnimator(mtv_giftNum);
 }
 }

 /**
 * 获取礼物
 */
 private View getNewGiftView(String tag) {

 // 添加标识, 该view若在layout中存在，就不在生成（用于findViewWithTag判断是否存在）
 View giftView = LayoutInflater.from(myContext).inflate(R.layout.item_gift, null);
 giftView.setTag(tag);

 // 添加标识, 记录生成时间，回收时用于判断是否是最新的，回收最老的
 ImageView iv_gift = giftView.findViewById(R.id.iv_gift);
 iv_gift.setTag(System.currentTimeMillis());

 // 添加标识，记录礼物个数
 MagicTextView mtv_giftNum = giftView.findViewById(R.id.mtv_giftNum);
 mtv_giftNum.setTag(1);
 mtv_giftNum.setText("x1");

 switch (tag) {
 case "gift01":
 iv_gift.setImageResource(GiftIcon[0]);
 break;
 case "gift02":
 iv_gift.setImageResource(GiftIcon[1]);
 break;
 case "gift03":
 iv_gift.setImageResource(GiftIcon[2]);
 break;
 case "gift04":
 iv_gift.setImageResource(GiftIcon[3]);
 break;
 }

 LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
 lp.topMargin = 10;
 giftView.setLayoutParams(lp);

 return giftView;
 }

 @Override
 public void onClick(View v) {
 switch (v.getId()) {
 case R.id.btn_gift01: // 礼物1,送香皂
 showGift("gift01");
 break;
 case R.id.btn_gift02: // 礼物2,送玫瑰
 showGift("gift02");
 break;
 case R.id.btn_gift03: // 礼物3,送爱心
 showGift("gift03");
 break;
 case R.id.btn_gift04: // 礼物4,送蛋糕
 showGift("gift04");
 break;
 }
 }

礼物移出动画

实现的效果如下：

礼物移出时使用accelerate_interpolator加速差值器

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
 android:duration="500"
 android:fromYDelta="0%p"
 android:interpolator="@android:anim/accelerate_interpolator"
 android:toYDelta="-100%p">
</translate>

 /**
 * 移除礼物列表里的giftView
 */
 private void removeGiftView(final int index) {
 // 移除列表，外加退出动画
 final View removeGiftView = ll_gift_group.getChildAt(index);
 outAnim.setAnimationListener(new Animation.AnimationListener() {

 @Override
 public void onAnimationStart(Animation animation) {
 }

 @Override
 public void onAnimationRepeat(Animation animation) {
 }

 @Override
 public void onAnimationEnd(Animation animation) {
 ll_gift_group.removeViewAt(index);
 }
 });

 // 开启动画，因为定时原因，所以可能是在子线程
 getActivity().runOnUiThread(new Runnable() {
 @Override
 public void run() {
 removeGiftView.startAnimation(outAnim);
 }
 });
 }

如果显示的礼物大于3种，就将最早的那种礼物移除：

// 是否有该tag类型的礼物
 if (newGiftView == null) {
 // 判断礼物列表是否已经有3个了，如果有那么删除掉一个没更新过的, 然后再添加新进来的礼物，始终保持只有3个
 if (ll_gift_group.getChildCount() >= 3) {
 // 获取前2个元素的最后更新时间
 View giftView01 = ll_gift_group.getChildAt(0);
 ImageView iv_gift01 = giftView01.findViewById(R.id.iv_gift);
 long lastTime1 = (long) iv_gift01.getTag();

 View giftView02 = ll_gift_group.getChildAt(1);
 ImageView iv_gift02 = giftView02.findViewById(R.id.iv_gift);
 long lastTime2 = (long) iv_gift02.getTag();

 if (lastTime1 > lastTime2) { // 如果第二个View显示的时间比较长
 removeGiftView(1);
 } else { // 如果第一个View显示的时间长
 removeGiftView(0);
 }
 }
...

开启定时清理礼物列表

礼物显示超过一定时间，自动将礼物在礼物列表中移除：

 /**
 * 定时清理礼物列表信息
 */
 private void clearTiming() {
 Timer timer = new Timer();
 timer.schedule(new TimerTask() {

 @Override
 public void run() {
 int childCount = ll_gift_group.getChildCount();
 long nowTime = System.currentTimeMillis();
 for (int i = 0; i < childCount; i++) {

 View childView = ll_gift_group.getChildAt(i);
 ImageView iv_gift = (ImageView) childView.findViewById(R.id.iv_gift);
 long lastUpdateTime = (long) iv_gift.getTag();

 // 更新超过3秒就刷新
 if (nowTime - lastUpdateTime >= 3000) {
 removeGiftView(i);
 }
 }
 }
 }, 0, 3000);
 }

聊天实现

case R.id.tv_chat:// 聊天
 tv_chat.setVisibility(View.GONE);
 ll_inputparent.setVisibility(View.VISIBLE);
 ll_inputparent.requestFocus(); // 获取焦点
 showKeyboard();
 break;
 case R.id.tv_send:// 发送消息
 String chatMsg = et_chat.getText().toString();
 if (!TextUtils.isEmpty(chatMsg)) {
 messageData.add("小明: " + chatMsg);
 et_chat.setText("");
 messageAdapter.NotifyAdapter(messageData);
 lv_message.setSelection(messageData.size());
 }
 hideKeyboard();
 break;

 /**
 * 显示软键盘
 */
 private void showKeyboard() {
 InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
 imm.showSoftInput(et_chat, InputMethodManager.SHOW_FORCED);
 }

 /**
 * 隐藏软键盘
 */
 public void hideKeyboard() {
 InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
 imm.hideSoftInputFromWindow(et_chat.getWindowToken(), 0);
 }

 view.setOnClickListener(new View.OnClickListener() {

 @Override
 public void onClick(View v) {
 if (ll_inputparent.getVisibility() == View.VISIBLE) {
 tv_chat.setVisibility(View.VISIBLE);
 ll_inputparent.setVisibility(View.GONE);
 hideKeyboard();
 }
 }
 });

 // 软键盘监听
 SoftKeyBoardListener.setListener(getActivity(), new SoftKeyBoardListener.OnSoftKeyBoardChangeListener() {
 @Override
 public void keyBoardShow(int height) {/*软键盘显示：执行隐藏title动画，并修改listview高度和装载礼物容器的高度*/

 // 输入文字时的界面退出动画
 AnimatorSet animatorSetHide = new AnimatorSet();
 ObjectAnimator leftOutAnim = ObjectAnimator.ofFloat(rl_num, "translationX", 0, -rl_num.getWidth());
 ObjectAnimator topOutAnim = ObjectAnimator.ofFloat(ll_anchor, "translationY", 0, -ll_anchor.getHeight());
 animatorSetHide.playTogether(leftOutAnim, topOutAnim);
 animatorSetHide.setDuration(300);
 animatorSetHide.start();
 // 改变listview的高度
 dynamicChangeListviewH(90);
 dynamicChangeGiftParentH(true);
 }

 @Override
 public void keyBoardHide(int height) {/*软键盘隐藏：隐藏聊天输入框并显示聊天按钮，执行显示title动画，并修改listview高度和装载礼物容器的高度*/
 tv_chat.setVisibility(View.VISIBLE);
 ll_inputparent.setVisibility(View.GONE);
 // 输入文字时的界面进入时的动画
 AnimatorSet animatorSetShow = new AnimatorSet();
 ObjectAnimator leftInAnim = ObjectAnimator.ofFloat(rl_num, "translationX", -rl_num.getWidth(), 0);
 ObjectAnimator topInAnim = ObjectAnimator.ofFloat(ll_anchor, "translationY", -ll_anchor.getHeight(), 0);
 animatorSetShow.playTogether(leftInAnim, topInAnim);
 animatorSetShow.setDuration(300);
 animatorSetShow.start();

 // 改变listview的高度
 dynamicChangeListviewH(150);
 dynamicChangeGiftParentH(false);
 }
 });

 /**
 * 动态的修改listview的高度
 */
 private void dynamicChangeListviewH(int heightPX) {
 ViewGroup.LayoutParams layoutParams = lv_message.getLayoutParams();
 layoutParams.height = DisplayUtil.dip2px(getActivity(), heightPX);
 lv_message.setLayoutParams(layoutParams);
 }

 /**
 * 动态修改礼物父布局的高度
 */
 private void dynamicChangeGiftParentH(boolean showhide) {
 if (showhide) {// 如果软键盘显示中
 if (ll_gift_group.getChildCount() != 0) {

 // 判断是否有礼物显示，如果有就修改父布局高度，如果没有就不作任何操作
 ViewGroup.LayoutParams layoutParams = ll_gift_group.getLayoutParams();
 layoutParams.height = ll_gift_group.getChildAt(0).getHeight();
 ll_gift_group.setLayoutParams(layoutParams);
 }
 } else {
 // 如果软键盘隐藏中
 // 就将装载礼物的容器的高度设置为包裹内容
 ViewGroup.LayoutParams layoutParams = ll_gift_group.getLayoutParams();
 layoutParams.height = ViewGroup.LayoutParams.WRAP_CONTENT;
 ll_gift_group.setLayoutParams(layoutParams);
 }
 }
