在布局中添加一層外部布局，為了設(shè)置顏色
? ? android:id="@+id/layout"
? ? android:layout_width="match_parent"
? ? android:paddingTop="10dp"
? ? android:layout_height="wrap_content">
? ? ? ? android:id="@+id/infoTab"
? ? ? ? android:layout_width="match_parent"
? ? ? ? android:layout_height="60dp"
? ? ? ? app:background="@color/mainWhite"
? ? ? ? app:tabTextAppearance="@android:style/TextAppearance.Small"
? ? ? ? app:tabGravity="fill"
? ? ? ? app:tabIndicatorGravity="top"
? ? ? ? app:tabIndicatorColor="@color/colorAccent"
? ? ? ? app:tabIndicatorHeight="2dp"
? ? ? ? app:tabSelectedTextColor="@color/colorAccent"
? ? ? ? app:tabTextColor="@color/itemTextColor"/>

因?yàn)関iewpager是嵌套在ScrollView中的，所以自定義了Viewpager
自定義的viewpager實(shí)現(xiàn)了懸停并且重置了高度，在切換的時(shí)候高度會(huì)動(dòng)態(tài)變化
import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.RelativeLayout;
import java.util.HashMap;
import java.util.LinkedHashMap;
/**
* 添加懸停的viewpager
*/
public class FinanceViewPagerextends ViewPager {
private int current;
? ? private int height =0;
? ? /**
? ? * 保存position與對(duì)于的View
*/
? ? private HashMapmChildrenViews =new LinkedHashMap();
? ? private boolean scrollble =true;
? ? public FinanceViewPager(Context context) {
super(context);
? ? }
public FinanceViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
? ? }
@Override
? ? protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (mChildrenViews.size() >current) {
View child =mChildrenViews.get(current);
? ? ? ? ? ? if (child !=null) {
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
? ? ? ? ? ? ? ? height = child.getMeasuredHeight();
? ? ? ? ? ? }
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
? ? ? ? super.onMeasure(widthMeasureSpec, heightMeasureSpec);
? ? }
public void resetHeight(int current) {
this.current = current;
? ? ? ? if (mChildrenViews.size() > current) {
LinearLayout.LayoutParams layoutParams = (LinearLayout.LayoutParams) getLayoutParams();
? ? ? ? ? ? if (layoutParams ==null) {
layoutParams =new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, height);
? ? ? ? ? ? }else {
layoutParams.height =height;
? ? ? ? ? ? }
setLayoutParams(layoutParams);
? ? ? ? }
}
/**
? ? * 保存position與對(duì)于的View
*/
? ? public void setObjectForPosition(View view, int position) {
mChildrenViews.put(position, view);
? ? }
@Override
? ? public boolean onTouchEvent(MotionEvent ev) {
if (!scrollble) {
return true;
? ? ? ? }
return super.onTouchEvent(ev);
? ? }
public boolean isScrollble() {
return scrollble;
? ? }
public void setScrollble(boolean scrollble) {
this.scrollble = scrollble;
? ? }
}
然后就是代碼設(shè)置
private void initTab(int select) {
tabTitles.clear();
? ? tabTitles.add("1111");
? ? tabTitles.add("2222");
? ? tabFragments.clear();
? ? for (int i =0; i
Bundle bundle =new Bundle();
? ? ? ? switch (i) {
case 0:
Fragment1 holdFragment =new Fragment1?(viewPager, 0);
? ? ? ? ? ? ? ? holdFragment.setArguments(bundle);
? ? ? ? ? ? ? ? tabFragments.add(holdFragment);
break;
? ? ? ? ? ? case 1:
Fragment2 mFragment2=new Fragment2?(viewPager, 2);
mFragment2.setArguments(bundle);
? ? ? ? ? ? ? ? tabFragments.add(mFragment2);
break;
? ? ? ? }
}
if (tabAdapter ==null) {
tabAdapter =new FragAdapterUpTitle(getChildFragmentManager(), tabFragments, tabTitles);
? ? }
viewPager.setAdapter(tabAdapter);
? ? infoTab.setupWithViewPager(viewPager);
? ? viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
? ? ? ? public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
? ? ? ? public void onPageSelected(int position) {
viewPager.resetHeight(position);
? ? ? ? ? ? viewPager.setCurrentItem(position);
? ? ? ? ? ? index =infoTab.getTabAt(position).getPosition();
? ? ? ? }
@Override
? ? ? ? public void onPageScrollStateChanged(int state) {
}
});
? ? viewPager.resetHeight(0);
? ? infoTab.setBackgroundColor(SkinCompatResources.getColor(getContext(), R.color.mainWhite));
? ? infoTab.getTabAt(select).select();
? ? ScrollView.setScrollViewListener(new FinanceScrollView.ScrollViewListener() {
@Override
? ? ? ? public void onScrollChanged(FinanceScrollView scrollView, int l, int t, int oldl, int oldt) {
if (t >topRL.getHeight() &&infoTab.getParent() ==layout) {
layout.removeView(infoTab);
? ? ? ? ? ? ? ? rl_layout.addView(infoTab);
? ? ? ? ? ? }else if (t
rl_layout.removeView(infoTab);
? ? ? ? ? ? ? ? layout.addView(infoTab);
? ? ? ? ? ? }
}
});
}
最后重寫一個(gè)適配器，主要是為了動(dòng)態(tài)的修改tab的名字
