有的时候我们生成库文件，需要在里面加入一些UI，并提供出一些xml的资源，那如何在其他项目中使用呢？
我们只需要在需要生成库文件的代码中不要直接是用R. ，而是使用自己写的方法获取。
下面上代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 |

使用方法：在要生成库文件的Java文件中，使用
1 2 |
View view = getLayoutInflater().inflate(ResUtil.getResofR(this).getLayout("activity_main"), null);
set
