I want to make an activity that contains a viewpager and listview below it which you can scroll them both .. like these apps ... anyone can help

推荐答案

好吧，我可以用一些方法通过测量在ListView的高度，并添加列表视图和视图寻呼机进入滚动视图这里的样品我做了这样做

Well I could do it with some way by measuring the height of the listView and adding the listview and the view pager into scroll view here's the sample I've made

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" };

}

和这里的如何我衡量ListView的高度

and here's how I measure the listView height

  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>
