java– 每秒传递不同的图像片段

概述试图每秒动态传递不同的图像片段,我无法在onCreateView方法和if语句中正确设置它.所有图像都存储在可绘制文件中.第二个布局的名称是maps和ImageViewid是android：id=“@id/map_images”分段publicclassFragment1extendsFragment{StringstringValue;intima

试图每秒动态传递不同的图像片段,我无法在onCreateVIEw方法和if语句中正确设置它.所有图像都存储在可绘制文件中.

第二个布局的名称是maps和ImageVIEw ID是androID：ID =“@ ID / map_images”

分段

public class Fragment1 extends Fragment {    String stringValue;    int imagesResID;    TextVIEw text;    String[] rbData;    RadioGroup radiobuttons;    boolean mAPImage;    VIEw answer;    public Fragment1(String str, int imageVIEw , String[] rb, boolean arg) {        this.stringValue = str;        this.imagesResID = imageVIEw;        this.rbData = rb;        this.mAPImage = arg;    }    @OverrIDe    public VIEw onCreateVIEw(LayoutInflater inflater, VIEwGroup container,                             Bundle savedInstanceState) {        Log.i("x","onCreateVIEwFragment");        VIEw vIEw = inflater.inflate(R.layout.fragment_1, container, false);        text =  vIEw.findVIEwByID(R.ID.textVIEw);        ImageVIEw imageResID = vIEw.findVIEwByID(image);        answer = vIEw.findVIEwByID((R.ID.radioGroup));        ImageVIEw maps  = vIEw.findVIEwByID(map_images);        text.setText(stringValue);        imageResID.setimageResource(imagesResID);        maps.                                            //HERE        if (mAPImage) {            vIEw = inflater.inflate(R.layout.maps, container, false);            maps = vIEw.findVIEwByID(map_images);            maps.                                         //HERE        } else {            vIEw = inflater.inflate(R.layout.fragment_1, container, false);            text =  vIEw.findVIEwByID(R.ID.textVIEw);            radiobuttons = vIEw.findVIEwByID(R.ID.radioGroup);            text.setText(stringValue);            imageResID.setimageResource(imagesResID);            //checkBoxes, textvIEws, imagevIEws, etc        }        if (answer != null) {            for (int i = 0; i < radiobuttons.getChildCount(); i++) {                ((Radiobutton) radiobuttons.getChildAt(i)).setText(rbData[i]);            }        }        return vIEw;    }

主要活动

fragmentList = new ArrayList<>();    fragmentList.add(new Fragment1(getResources().getString(R.string.text_page_1), R.drawable.swans, new String[]{getResources().getString(R.string.answer1), getResources().getString(R.string.answer2),getResources().getString(R.string.answer3)},false));    fragmentList.add(new Fragment1(null, R.drawable.image_file, null, true));    // TALKING ABOUT THIS liNE HERE AND LATER EVERY SECOND FRAGMENT. JUST IMAGE WILL CHANGE.    fragmentList.add(new Fragment1(getResources().getString(R.string.text_page_2), R.drawable.nature, new String[]{getResources().getString(R.string.answer4), getResources().getString(R.string.answer5),getResources().getString(R.string.answer6)},false));

布局

enter image description here

这是我询问的vIEwPager和fragmentList

    public class PagerAdapter extends FragmentStatePagerAdapter {                             //line 3    List<Fragment> fragmentList;                                                    //line 4    public PagerAdapter(FragmentManager fm, List<Fragment> fragmentList) {          //line 5        super(fm);                                                                  //line 6        this.fragmentList = fragmentList;                                           //line 7    }    @OverrIDe    public Fragment getItem(int position) {                                         //line 8        return fragmentList.get(position);                                          //line 9    }    @OverrIDe    public int getCount() {                                                         //line 10        return fragmentList.size();                                                 //line 11    }}

那么如何使用vIEwPager动态更改此布局？

解决方法:

如果要从Activity传递数据片段,请尝试使用静态静态工厂方法作为以下代码.

片段1

public static Fragment newInstance(String str, int imageVIEw , String[] rb, boolean arg) {    Fragment fragment = new Fragment1();    Bundle args = new Bundle();    args.putString("str", str);    args.putInt("image_resID", imageVIEw);    args.putStringArray("rb", rb);    args.putBoolean("arg", arg);    fragment.setArguments(args);    return fragment;}@OverrIDepublic voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    Bundle args = getArguments();    stringValue = args.getString("str");    imagesResID = args.getInt("image_resID");    rbData = args.getStringArray("rb");    mAPImage = args.getBoolean("arg");}

主要活动

fragmentList = new ArrayList<>();fragmentList.add(Fragment1.newInstance(getResources().getString(R.string.text_page_1), R.drawable.swans, new String[]{getResources().getString(R.string.answer1), getResources().getString(R.string.answer2),getResources().getString(R.string.answer3)},false));fragmentList.add(Fragment1.newInstance(null, R.drawable.image_file, null, true));    // TALKING ABOUT THIS liNE HERE AND LATER EVERY SECOND FRAGMENT. JUST IMAGE WILL CHANGE.fragmentList.add(Fragment1.newInstance(getResources().getString(R.string.text_page_2), R.drawable.nature, new String[]{getResources().getString(R.string.answer4), getResources().getString(R.string.answer5),getResources().getString(R.string.answer6)},false));
