41 | } 42 | 43 | @Override 44 | public void OnError(int code, String errorMsg) { 45 | 46 | } 47 | }); 48 | 49 | （2）、单个图片压缩，多线程模式 50 | new GDCompressC(MainActivity.this, 51 | new GDConfig().setmPath(tempCompressImgPath), new GDCompressImageListener() { 52 | @Override 53 | public void OnSuccess(String path) { 54 | MainActivity.this.runOnUiThread(new Runnable() { 55 | @Override 56 | public void run() { 57 | 58 | } 59 | }); 60 | } 61 | 62 | @Override 63 | public void OnError(int code, String errorMsg) { 64 | 65 | } 66 | }); 67 | 68 | （3）、单个图片压缩，单线程模式 69 | String tempCompressImgPath = mSelectedPath.get(0);// 70 | GDImageBean imageBeana = new GDImageBean(); 71 | imageBeana.setmGDConfig(new GDConfig().setmPath(tempCompressImgPath)); 72 | new GDCompressA(MainActivity.this, imageBeana 73 | , new GDCompressImageListenerA() { 74 | GDCompressImageListener() { 75 | @Override 76 | public void OnSuccess(GDImageBean gdImageBean) { 77 | MainActivity.this.runOnUiThread(new Runnable() { 78 | @Override 79 | public void run() { 80 | 81 | } 82 | }); 83 | } 84 | 85 | @Override 86 | public void OnError(GDImageBean gdImageBean) { 87 | 88 | } 89 | }); 90 | 91 | （4）、批量压缩，多线程模式，速度快，但OOM几率大 92 | GDCompressC gdCompressC = new GDCompressC(MainActivity.this, new GDCompressImageListener() { 93 | @Override 94 | public void OnSuccess(String path) { 95 | Log.i(TAG, "OnSuccess: ===批量=====图片压缩=====btn_img_c2========path==" + path); 96 | } 97 | 98 | @Override 99 | public void OnError(int code, String errorMsg) { 100 | Log.i(TAG, "OnError: ===批量=====图片压缩=====btn_img_c2=========="); 101 | } 102 | }); 103 | for (int i = 0; i < mSelected.size(); i++) { 104 | gdCompressC.start(new GDConfig().setmPath(mSelectedPath.get(i))); 105 | } 106 | 107 | （5）、批量压缩，单线程模式，速度慢，但OOM几率小很多 108 | GDCompressA gdCompressA = new GDCompressA(MainActivity.this, new GDCompressImageListenerA() { 109 | @Override 110 | public void OnSuccess(GDImageBean gdImageBean) { 111 | Log.i(TAG, "OnSuccess: ===批量=====图片压缩=====btn_img_c3========path==" + gdImageBean.getmGDConfig().getmPath()); 112 | } 113 | 114 | @Override 115 | public void OnError(GDImageBean gdImageBean) { 116 | Log.i(TAG, "OnError: ===批量=====图片压缩=====btn_img_c3=========="); 117 | } 118 | }); 119 | for (int i = 0; i < mSelected.size(); i++) { 120 | GDImageBean imageBeana = new GDImageBean(); 121 | imageBeana.setmGDConfig(new GDConfig().setmPath(mSelectedPath.get(i))); 122 | gdCompressA.start(imageBeana); 123 | } 124 | 125 | （6）、多个图片同时压缩（GDConfig中属性下边统一解释） 126 | 注：这里OnError方法中返回的数据GDImageBean中通过code字段来判断图片是否成功压缩；而OnSuccess方法中所有的图片都是压缩完成的（即只要有一 个图片压缩失败都是回调OnError方法）。 127 | List imageBeans = new ArrayList<>(); 128 | for (int i = 0; i < selectList.size(); i++) { 129 | final String imgpath = selectList.get(i).getPath(); 130 | imageBeans.add(new GDImageBean(new GDConfig().setmPath(imgpath))); 131 | } 132 | new GDCompressImageS(SendCircleActivity.this, imageBeans, new GDCompressImageSListener() { @Override 133 | public void OnSuccess(List imageBeanList) { 134 | 135 | } 136 | 137 | @Override 138 | public void OnError(List imageBeanList) { 139 | 140 | } 141 | }); 142 | 143 | （7）、GDConfig中属性统一解释 144 | new GDConfig() 145 | .setmPath(tempCompressImgPath)//要压缩图片的原路径 146 | .setSavePath(tempCompressImgPath)//压缩图片的保存路径，如果不设置将替换原文件 147 | .setChangeWH(true)//是否要进行调整图片分辨率以压缩到更小 148 | .setWidth(720)//需要调整分辨率的时候有效，压缩后的宽度（按比例计算后的，而不是直接使用这个） 149 | .setHeight(1280)//需要调整分辨率的时候有效，压缩后的高度（按比例计算后的，而不是直接使用这个） 150 | 151 | 152 | 联系作者：QQ：1772889689 邮箱：1772889689@qq.com 微信：gdihh8180 153 | 注：联系请注明联系目的 154 | -------------------------------------------------------------------------------- /app/.gitignore: -------------------------------------------------------------------------------- 1 | /build 2 | -------------------------------------------------------------------------------- /app/build.gradle: -------------------------------------------------------------------------------- 1 | apply plugin: 'com.android.application' 2 | 3 | android { 4 | compileSdkVersion 27 5 | defaultConfig { 6 | applicationId "com.wgd.myimagelibrary" 7 | minSdkVersion 15 8 | targetSdkVersion 27 9 | versionCode 1 10 | versionName "1.0" 11 | testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" 12 | } 13 | buildTypes { 14 | release { 15 | minifyEnabled false 16 | proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 17 | } 18 | } 19 | } 20 | 21 | dependencies { 22 | implementation fileTree(include: ['*.jar'], dir: 'libs') 23 | implementation 'com.android.support:appcompat-v7:27.1.1' 24 | implementation 'com.android.support.constraint:constraint-layout:1.1.2' 25 | testImplementation 'junit:junit:4.12' 26 | androidTestImplementation 'com.android.support.test:runner:1.0.2' 27 | androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' 28 | implementation 'com.google.code.gson:gson:2.8.2' 29 | /*6.0权限申请依赖库 RxPermissions 和 RxJava2*/ 30 | //RxPermissions 31 | implementation 'com.tbruyelle.rxpermissions2:rxpermissions:0.9.4@aar' 32 | //RxJava2 33 | implementation 'io.reactivex.rxjava2:rxjava:2.+' 34 | 35 | /* View注解依赖库 butterknife 项目地址：https://github.com/JakeWharton/butterknife*/ 36 | implementation 'com.jakewharton:butterknife:8.8.1' 37 | annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1' 38 | /* 知乎开源的图片选择库 使用uri */ 39 | implementation 'com.zhihu.android:matisse:0.+' 40 | /* 图片加载框架 */ 41 | // implementation 'com.github.bumptech.glide:glide:3.8.0' 42 | implementation 'com.github.bumptech.glide:glide:3.+' 43 | annotationProcessor 'com.github.bumptech.glide:compiler:4.3.1' 44 | implementation 'com.android.support:multidex:1.0.1' 45 | implementation project(':gdcplibrary') 46 | } 47 | -------------------------------------------------------------------------------- /app/src/main/AndroidManifest.xml: -------------------------------------------------------------------------------- 1 | 2 | 4 | 5 | 6 | 7 | 8 | 9 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 | 31 | 34 | 35 | 36 | 37 | 38 | 39 | -------------------------------------------------------------------------------- /app/src/main/java/com/wgd/myimagelibrary/App.java: -------------------------------------------------------------------------------- 1 | package com.wgd.myimagelibrary;
