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:
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:
用户交互页 LayerFrag:
public class LayerFrag extends Fragment { @Nullable @Override public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { return inflater.inflate(R.layout.frag_layer, null); }}
frag_layer:
EmptyFrag:
/** * 空的fragment */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); }}
frag_empty.xml:
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 :
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
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:
/** * 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
/** * 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); } }
MagicTextView代码
