如果要像我那樣顯示全的話蛤虐，需要自己定義修改下ViewPager的代碼
CustomViewPager的代碼如下
public class CustomViewPager extends ViewPager {
private Map<Integer, View> map = new HashMap<>(3);
private int currentPage;
int height = 0;
public CustomViewPager(Context context) {
super(context);
}
public CustomViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}
/**
* 作者：GaoXX
* 創(chuàng)建時間:2017/11/8
* 注釋描述:測量高度
*/
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
if (map.size() > currentPage) {
View view = map.get(currentPage);//獲取當(dāng)前視圖的view
view.measure(widthMeasureSpec,MeasureSpec.makeMeasureSpec(0,MeasureSpec.UNSPECIFIED));//測量當(dāng)前view的寬高醉箕，高度就是測量的實際大小值
height = view.getMeasuredHeight();//獲取測試的高度
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height,MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
/**
* 作者：GaoXX
* 創(chuàng)建時間:2017/11/8
* 注釋描述:在切換tab的時候培愁，重置ViewPager的高度
*/
public void resetHeight(int current) {
this.currentPage = current;//獲取切換的tab
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) getLayoutParams();
setLayoutParams(params);//會重新刷新onMeasure方法
}
/**
* 獲取竿痰、存儲每一個tab的高度凡傅，在需要的時候顯示存儲的高度
*
* @param current tab的position
* @param view 當(dāng)前tab的高度
*/
public void addHeight(int current, View view) {
map.put(current, view);
}
}
這里主要是etLayoutParams(params);這個方法會重新調(diào)用measure
MainActivity:
public class MainActivity extends Activity implements View.OnClickListener {
CustomViewPager myViewPager;
TextView tvProductInformation;
TextView tvPurchaseNotes;
TextView tvDepartureUser;
public static final int TAB_PRODUCT = 0;//商品信息
public static final int TAB_PURCHASE = 1;//購買須知
public static final int TAB_DEPARTUSER = 2;//參團(tuán)用戶
private int currentTab = 0;
private List<View> viewList = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myViewPager = (CustomViewPager) this.findViewById(R.id.myViewPager);
tvProductInformation = (TextView) this.findViewById(R.id.tv_merchandise_Product_Information);
tvPurchaseNotes = (TextView) this.findViewById(R.id.tv_merchandise_purchase_notes);
tvDepartureUser = (TextView) this.findViewById(R.id.tv_merchandise_DepartureUser);
initProductInformation();//初始化商品信息

initmvpShoppBuyUser();
for (int i = 0; i < viewList.size(); i++) {
myViewPager.addHeight(i, viewList.get(i));
}
myViewPager.resetHeight(0);
