與recyclerView
gradle:
compile 'com.android.support:design:26.0.0-alpha1'//材料設計語言
compile 'com.jakewharton:butterknife:8.5.1'//butterknife可以實現繫結控制元件
annotationProcessor 'com.jakewharton:butterknife-compiler:8.5.1'//butterknife可以實現繫結控制元件
compile 'com.zhy:base-rvadapter:3.0.3'//recyclerView萬能介面卡

自定義view
public class MyListView extends ListView {
public MyListView (Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int mExpandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
super.onMeasure(widthMeasureSpec, mExpandSpec);
}
}
