android studio使用百分比布局
糖醋咸鱼 2017-09-19 05:43:26 dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'
}
我在上面按照书本添加compile 'com.android.support:recyclerview-v7:24.2.1会提示错误,
我把24.2.1改成25.0.0就可以了,改成25.3.1就不行。请问这是什么回事?
