注意：在child_layout.xml裡面的這個元件必須是自己的專案名
需要改一下 直接輸入Add就出來了
<com.bw.gouwuche.AddDeleteView android:id="@+id/adv_main" android:layout_width="wrap_content" android:layout_height="wrap_content" app:left_text="-" app:middle_text="3" app:right_text="+"/>
1.導依賴
compile 'com.squareup.okhttp3:okhttp:3.4.1' compile 'com.jakewharton:butterknife:8.8.1'annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1' compile 'com.facebook.fresco:fresco:0.12.0' compile 'org.greenrobot:eventbus:3.1.1' compile 'io.reactivex.rxjava2:rxjava:2.1.7' compile 'io.reactivex.rxjava2:rxandroid:2.0.1' compile 'com.squareup.retrofit2:retrofit:2.3.0' compile 'com.squareup.retrofit2:converter-gson:2.3.0'compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0' compile 'com.github.bumptech.glide:glide:3.7.0' compile 'com.android.support:recyclerview-v7:23.2.0'
2.加許可權
<uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
3.配置App
android:name=".app.MyApplication"
4.分包 bean adapter api app model presenter view utils
delete interceptor event 這些包
