视频直播网站源码，自定义气泡效果（BubbleView）
代码如下：

package com.example.myapplication;import android.content.Context;
import android.graphics.BlurMaskFilter;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.RectF;

import android.util.Log;
import android.util.TypedValue;
import android.view.View;import androidx.annotation.Nullable;import java.util.ArrayList;
import java.util.List;
import java.util.Random;public class BubbleView extends View {private int mBubbleMaxRadius = 15;          // 气泡最大半径 pxprivate int mBubbleMinRadius = 8;           // 气泡最小半径 pxprivate int mBubbleMaxSize = 50;            // 气泡数量private int mBubbleRefreshTime = 50;        // 刷新间隔private int mBubbleMaxSpeedY = 2;           // 气泡速度private int mBubbleMaxSpeedX = 4;           // 气泡速度private int mBubbleAlpha = 128;             // 气泡画笔private float mContentWidth;                 // 瓶子宽度private float mContentHeight;                // 瓶子高度private RectF mContentRectF;                // 实际可用内容区域private Paint mBubblePaint;                 // 气泡画笔public BubbleView(Context context) {this(context, null);}public BubbleView(Context context, @Nullable AttributeSet attrs) {this(context, attrs, 0);}public BubbleView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {super(context, attrs, defStyleAttr);mContentWidth = dp2px(130);mContentHeight = dp2px(260);mBubblePaint = new Paint();mBubblePaint.setColor(Color.GREEN);mBubblePaint.setAlpha(mBubbleAlpha);}@Overrideprotected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {super.onMeasure(widthMeasureSpec, heightMeasureSpec);int widthSpecMode = MeasureSpec.getMode(widthMeasureSpec);int widthSize = MeasureSpec.getSize(widthMeasureSpec);int heightSize = MeasureSpec.getSize(heightMeasureSpec);int heightSpecMode = MeasureSpec.getMode(heightMeasureSpec);int width;int height;if (widthSpecMode == MeasureSpec.EXACTLY || widthSpecMode == MeasureSpec.AT_MOST) {width = widthSize;mContentWidth = width;} else {width = (int) mContentWidth;}if (heightSpecMode == MeasureSpec.EXACTLY || heightSpecMode == MeasureSpec.AT_MOST) {height = heightSize;mContentHeight = height;} else {height = (int) mContentHeight;}setMeasuredDimension(width, height);}@Overrideprotected void onSizeChanged(int w, int h, int oldw, int oldh) {super.onSizeChanged(w, h, oldw, oldh);mContentRectF = new RectF(getPaddingLeft(), getPaddingTop(), w - getPaddingRight(), h - getPaddingBottom());}@Overrideprotected void onDraw(Canvas canvas) {super.onDraw(canvas);drawBubble(canvas);}@Overrideprotected void onAttachedToWindow() {super.onAttachedToWindow();startBubbleSync();}

目前为自定义属性，布局文件中直接引用即可。

  <com.example.myapplication.BubbleViewandroid:layout_width="300dp"android:layout_height="100dp"/>
