使用fill_parent进行Android viewpager宽度问题？

Question

大家好我这里有viewpager宽度问题.这不是全屏宽度.你能回答我吗？

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:id="@+id/project_detail_layout"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
   android:id="@+id/pager"
   android:layout_width="match_parent"
   android:layout_height="fill_parent"
   />
<com.viewpagerindicator.CirclePageIndicator
   android:id="@+id/indicator"
   android:padding="10dip"
   android:layout_height="wrap_content"
   android:layout_width="fill_parent"
   android:layout_alignParentTop="true"
   />

片段代码就是这样.我在这里动态添加图像.图像从chache或sdcards加载或在任何一种情况下下载.

public static class ArrayListFragment extends Fragment {
    int mNum;

    static ArrayListFragment newInstance(int num) {
        ArrayListFragment f = new ArrayListFragment();

        // Supply num input as an argument.
        Bundle args = new Bundle();
        args.putInt("num", num);
        f.setArguments(args);

        return f;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mNum = getArguments() != null ? getArguments().getInt("num") : 1;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        ImageView image = new ImageView(getActivity());
        //image.setImageBitmap(bitmap.get(mNum));
        imageLoader.DisplayImage(bitmap.get(mNum), image);
        LinearLayout layout = new LinearLayout(getActivity());
        layout.setLayoutParams(new LayoutParams(android.widget.RelativeLayout.LayoutParams.MATCH_PARENT, android.widget.RelativeLayout.LayoutParams.MATCH_PARENT));
        layout.setGravity(Gravity.CENTER);
        layout.addView(image);  
        return layout;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
       // setListAdapter(new ArrayAdapter<String>(getActivity(),
             //   android.R.layout.simple_list_item_1, Cheeses.sCheeseStrings));
    }

}

你能告诉我我在哪里错了吗？

更改布局宽度以匹配父级

android:layout_width="MATCH_PARENT"

您可以将此行添加到您的ImageView的请

image.setScaleType(CENTER_CROP)
