今天發現設定viewpager高度為wrap_content時並沒作用。stackoverflow給出瞭解決方式,就是自己定義viewpager,重寫onMesure()方法:
public class WrapContentHeightViewPager extends ViewPager { /** * Constructor * * @param context the context */ public WrapContentHeightViewPager(Context context) { super(context); } /** * Constructor * * @param context the context * @param attrs the attribute set */ public WrapContentHeightViewPager(Context context, AttributeSet attrs) { super(context, attrs); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int height = 0; for(int i = 0; i < getChildCount(); i++) { View child = getChildAt(i); child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED)); int h = child.getMeasuredHeight(); if(h > height) height = h; } heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY); super.onMeasure(widthMeasureSpec, heightMeasureSpec); }}
使用的時候用WrapContentHeightViewPager取代viewpager就ok了
