ViewPager中height=wrap_content无效
public class MyViewPager extends ViewPager { @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int childCount = getChildCount(); int height = 0; int expandSpec = 0; for (int i = 0; i < childCount; i++) { View child = getChildAt(i); ViewGroup.LayoutParams lp = child.getLayoutParams(); measureChild(child, widthMeasureSpec, heightMeasureSpec); child.measure(widthMeasureSpec, getChildMeasureSpec(heightMeasureSpec, 0, lp.height)); int childHeight = child.getMeasuredHeight(); if (childHeight > height){ height = childHeight; } expandSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY); } super.onMeasure(widthMeasureSpec, expandSpec); } public MyViewPager(@NonNull Context context) { super(context); } public MyViewPager(@NonNull Context context, @Nullable AttributeSet attrs) { super(context, attrs); } }
ScrollView里边用ListView显示不全
public class MyListView extends ListView { public MyListView(Context context, AttributeSet attrs) { super(context, attrs); } /** * 自己测量解决显示不全的问题 * @param widthMeasureSpec * @param heightMeasureSpec */ @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); } }
inflate(R.layout.activity_main, parent, false)解决设置无效问题，包一层不行
setContentView(R.layout.activity_main);
AppCompatActivity###
@Override
public void setContentView(@LayoutRes int layoutResID) {
getDelegate().setContentView(layoutResID);
}
abstract class AppCompatDelegate的实现类AppCompatDelegateImpl###
@Override
public void setContentView(int resId) {
ensureSubDecor();
ViewGroup contentParent = mSubDecor.findViewById(android.R.id.content);
contentParent.removeAllViews();
LayoutInflater.from(mContext).inflate(resId, contentParent); /// 最终调用inflate
mAppCompatWindowCallback.getWrapped().onContentChanged();
}
abstract class LayoutInflater###
public View inflate(XmlPullParser parser, @Nullable ViewGroup root, boolean attachToRoot) {
……………………………………………………………………………………
final View temp = createViewFromTag(root, name, inflaterContext, attrs); //1
……………………………………………………………………………………
temp.setLayoutParams(params); //2
……………………………………………………………………
rInflateChildren(parser, temp, attrs, true);
………………………………………………………………………………
root.addView(temp, params);
………………………………………………………………………………
if (root == null || !attachToRoot) {
result = temp;
}
return result;
}
}
