好吧,我可以通过测量 listView 的高度并将 listview 和视图寻呼机添加到滚动视图中以某种方式做到这一点,这是我制作的示例
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list);
ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
ViewPagerAdapter adapter = new ViewPagerAdapter(this, imageArra);
myPager.setAdapter(adapter);
myPager.setCurrentItem(0);
myPager.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
PointF downP = new PointF();
PointF curP = new PointF();
int act = event.getAction();
if (act == MotionEvent.ACTION_DOWN
|| act == MotionEvent.ACTION_MOVE
|| act == MotionEvent.ACTION_UP) {
((ViewGroup) v).requestDisallowInterceptTouchEvent(true);
if (downP.x == curP.x && downP.y == curP.y) {
return false;
}
}
return false;
}
});
Aadpater aa = new Aadpater(this, text);
final ListView ll = (ListView) findViewById(R.id.listView);
ll.setAdapter(aa);
Utility.setListViewHeightBasedOnChildren(ll);
}
private int imageArra[] = { R.drawable.about_logo, R.drawable.ic_launcher,
R.drawable.nagy_cv, R.drawable.rewrew };
private String text[] = { "one", "two", "three", "four", " five", "six",
"seven", "eight", "one", "two", "three", "four", " five", "six",
"seven", "eight", "one", "two", "three", "four", " five", "six",
"seven", "eight", "one", "two", "three", "four", " five", "six",
"seven", "eight", "one", "two", "three", "four", " five", "six",
"seven", "eight" };
}
这是我测量listView高度的方法
public class Utility {
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
// pre-condition
return;
}
int totalHeight = 0;
int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(),
MeasureSpec.UNSPECIFIED);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, 0);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
listView.setLayoutParams(params);
listView.requestLayout();
}
}
这是我的布局
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/myfivepanelpager"
android:layout_width="fill_parent"
android:layout_height="300dp" />
<ListView
android:id="@+id/listView"
android:layout_width="match_parent"
android:layout_height="0dp" >
</ListView>
</LinearLayout>
</ScrollView>

我将 aViewPager
与 a 结合使用Title Strip
。
在 android 开发者网站上,您有一个很好的教程。
您需要以下对象:
FragmentActivity
FragmentStatePagerAdapter
(控制您当前的视图和滑动动作)Fragment
(在onCreateView()
你可以声明你的 SwipeViews 布局)
只需尝试本教程,如果您对某些问题有更多疑问,请告诉我。

好的,下次你应该尝试精确你的问题,如果你有代码而不是显示它。所以 SO 社区可以给你更精准更快速的帮助 :)
正如您在评论中描述的那样,您可以使用 aScrollView
而不是 a LinearLayout
。比你有两个选项可以让你的 listView 在 scrollView 内滚动:
- 选项 1:覆盖 onInterceptTouch
- 选项 2:Moisés Olmedo 在这篇文章中的回答(这真的很简单!)。
