我正在使用正在给布局充气的ViewPager。 ViewPager工作，我可以来回滑动，但我正在膨胀的布局只是部分加载。在我的示例中，只显示了我的RelativeLayout而没有其他内容。我可以确认我的布局有效，因为当我不使用ViewPager时，一切都显示正常。
这是我正在膨胀的布局：

以下是具有ViewPager的主要布局，并将使上述布局膨胀：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/scorePager"/>
</LinearLayout>
这是我的ViewPagerAdapter代码：
private class ScorePagerAdapter extends PagerAdapter{
@Override
public int getCount() {
return NUM_PAGES;
}
/**
* Create the page for the given position. The adapter is responsible
* for adding the view to the container given here, although it only
* must ensure this is done by the time it returns from
* {@link #finishUpdate()}.
*
* @param container The containing View in which the page will be shown.
* @param position The page position to be instantiated.
* @return Returns an Object representing the new page. This does not
* need to be a View, but can be some other container of the page.
*/
@Override
public Object instantiateItem(View collection, int position) {
/*TextView tv = new TextView(cxt);
tv.setText("Bonjour PAUG " + position);
tv.setTextColor(Color.GREEN);
tv.setTextSize(30);
((ViewPager) collection).addView(tv,0);
return tv;*/
LayoutInflater inflater = (LayoutInflater)cxt.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.score, null);
updateDisplay(score, position, view);
((ViewPager) collection).addView(view,0);
return view;
}
/**
* Remove a page for the given position. The adapter is responsible
* for removing the view from its container, although it only must ensure
* this is done by the time it returns from {@link #finishUpdate()}.
*
* @param container The containing View from which the page will be removed.
* @param position The page position to be removed.
* @param object The same object that was returned by
* {@link #instantiateItem(View, int)}.
*/
@Override
public void destroyItem(View collection, int position, Object view) {
//((ViewPager) collection).removeView((TextView) view);
((ViewPager) collection).removeView((View) view);
}
@Override
public boolean isViewFromObject(View view, Object object) {
//return view==((TextView)object);
return view==((View)object);
}
/**
* Called when the a change in the shown pages has been completed. At this
* point you must ensure that all of the pages have actually been added or
* removed from the container as appropriate.
* @param container The containing View which is displaying this adapter's
* page views.
*/
@Override
public void finishUpdate(View arg0) {}
@Override
public void restoreState(Parcelable arg0, ClassLoader arg1) {}
@Override
public Parcelable saveState() {
return null;
}
@Override
public void startUpdate(View arg0) {}
}
最后updateDisplay（）包含我想要显示的所有UI元素：
private void updateDisplay(final BlastScore score, int viewId, View layout) {
final TextView scoreTextView = (TextView) layout.findViewById(R.id.scoreTextView);
final TextView scoreLabelTextView = (TextView) layout.findViewById(R.id.scoreLabelTextView);
int blastScore = score.getBlastScore();
// animateScore();
// Swing Speed UI
final TextView leftPanelTextView = (TextView) layout.findViewById(R.id.leftPanelTextView);
final TextView leftPanelLabelTextView = (TextView) layout.findViewById(R.id.leftPanelLabelTextView);
final ImageView leftPanelImageView = (ImageView) layout.findViewById(R.id.leftPanelImageView);
final ImageView leftPanelSelectionArrow = (ImageView) layout.findViewById(R.id.leftPanelSelectionArrow);
// Ball Speed UI
final TextView middlePanelTextView = (TextView) layout.findViewById(R.id.middlePanelTextView);
final TextView middlePanelLabelTextView = (TextView) layout.findViewById(R.id.middlePanelLabelTextView);
final ImageView middlePanelImageView = (ImageView) layout.findViewById(R.id.middlePanelImageView);
final ImageView middlePanelSelectionArrow = (ImageView) layout.findViewById(R.id.middlePanelSelectionArrow);
答案 0 :(得分：1)
使RelativeLayout（标题）的layout_weight为1，并为FrameLayout（得分）设为0。
权重为0意味着它可以保证获得它要求的内容，并且由于它的高度是match_parent，因此RelativeLayout可以获得所有内容。
