排球图像作为下一个活动背景图像

概述这是一个简单的问题,但使我感到困惑.我有以下第一项活动和详细信息活动.第一次活动第二次活动作为第一个活动的列表视图,使用凌空下载了json数据,我能够将标题和图像发送到details活动,但是现在我想将传递的图像设置为details活动背景图片,这是我的第一个活动代码：主要活动：pub

这是一个简单的问题,但使我感到困惑.我有以下第一项活动和详细信息活动.

第一次活动

第二次活动

作为第一个活动的列表视图,使用凌空下载了Json数据,我能够将标题和图像发送到details活动,但是现在我想将传递的图像设置为details活动背景图片,这是我的第一个活动代码：

主要活动：

public class MainActivity extends Activity {// Log tagprivate static final String TAG = MainActivity.class.getSimplename();// MovIEs Json urlprivate static final String url = "http://API.androIDhive.info/Json/movIEs.Json";private ProgressDialog pDialog;private List<MovIE> movIEList = new ArrayList<MovIE>();private ListVIEw ListVIEw;private Customlistadapter adapter;private static String title="Title";private static String bitmap="thumbnailUrl";@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.activity_main);    Intent newActivity2=new Intent();    setResult(RESulT_OK, newActivity2);    ListVIEw = (ListVIEw) findVIEwByID(R.ID.List);    adapter = new Customlistadapter(this, movIEList);    ListVIEw.setAdapter(adapter);    pDialog = new ProgressDialog(this);    // Showing progress dialog before making http request    pDialog.setMessage("Loading...");    pDialog.show();    // changing action bar color    getActionbar().setBackgroundDrawable(            new colorDrawable(color.parsecolor("#1b1b1b")));    // Creating volley request obj    JsonArrayRequest movIEReq = new JsonArrayRequest(url,            new Response.Listener<JsONArray>() {                @OverrIDe                public voID onResponse(JsONArray response) {                    Log.d(TAG, response.toString());                    pDialog.dismiss();                    // Parsing Json                    for (int i = 0; i < response.length(); i++) {                        try {                            JsONObject obj = response.getJsONObject(i);                            MovIE movIE = new MovIE();                            movIE.setTitle(obj.getString("Title"));                            movIE.setthumbnailUrl(obj.getString("image"));                            movIE.setrating(((Number) obj.get("rating"))                                    .doubleValue());                            movIE.setYear(obj.getInt("releaseYear"));                            // Genre is Json array                            JsONArray genreArry = obj.getJsONArray("genre");                            ArrayList<String> genre = new ArrayList<String>();                            for (int j = 0; j < genreArry.length(); j++) {                                genre.add((String) genreArry.get(j));                            }                            movIE.setGenre(genre);                            // adding movIE to movIEs array                            movIEList.add(movIE);                        } catch (JsONException e) {                            e.printstacktrace();                        }                    }                    // notifying List adapter about data changes                    // so that it renders the List vIEw with updated data                    adapter.notifyDataSetChanged();                }            }, new Response.ErrorListener() {                @OverrIDe                public voID one rrorResponse(VolleyError error) {                    if (error instanceof NoConnectionError){                        Toast.makeText(getBaseContext(), "Bummer..There's No Internet connection!", Toast.LENGTH_LONG).show();                    }                }            });    // Adding request to request queue    AppController.getInstance().addToRequestQueue(movIEReq);    ListVIEw.setonItemClickListener(new AdapterVIEw.OnItemClickListener() {        @OverrIDe        public voID onItemClick(AdapterVIEw<?> parent, VIEw vIEw,                int position, long ID) {            // Todo auto-generated method stub            String name = ((TextVIEw) vIEw.findVIEwByID(R.ID.Title)).getText().toString();            bitmap = ((MovIE)movIEList.get(position)).getthumbnailUrl();            Intent intent = new Intent(MainActivity.this, Detail.class);                intent.putExtra(Title, name);            intent.putExtra("images", bitmap);            startActivity(intent);        }    });}@OverrIDepublic boolean onCreateOptionsMenu(Menu menu) {    // Inflate the menu; this adds items to the action bar if it is present.    getMenuInflater().inflate(R.menu.main, menu);    return true;}

}

这是“详细信息”活动：

public class Detail extends Activity{private static String Title = "Title";@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    // Todo auto-generated method stub    super.onCreate(savedInstanceState);    setContentVIEw(R.layout.detail);    getActionbar().hIDe();    Intent i = getIntent();    ImageLoader imageLoader = AppController.getInstance().getimageLoader();    String name = i.getStringExtra(Title);    String bitmap = i.getStringExtra("images");    NetworkImageVIEw thumbnail = (NetworkImageVIEw) findVIEwByID(R.ID.thumbnail);    thumbnail.setimageUrl(bitmap, imageLoader);    TextVIEw lblname = (TextVIEw) findVIEwByID(R.ID.name_label);    lblname.setText(name);}public voID onClickHandler(VIEw v){    switch(v.getID()){    case R.ID.thumbnail:startActivity(new Intent(this,MainActivity.class));    }}

}

如果需要,我会上传更多代码.

Coustomlistadapter：

public class Customlistadapter extends BaseAdapter {private Activity activity;private LayoutInflater inflater;private List<MovIE> movIEItems;ImageLoader imageLoader = AppController.getInstance().getimageLoader();public Customlistadapter(Activity activity, List<MovIE> movIEItems) {    this.activity = activity;    this.movIEItems = movIEItems;}@OverrIDepublic int getCount() {    return movIEItems.size();}@OverrIDepublic Object getItem(int location) {    return movIEItems.get(location);}@OverrIDepublic long getItemID(int position) {    return position;}@OverrIDepublic VIEw getVIEw(int position, VIEw convertVIEw, VIEwGroup parent) {    if (inflater == null)        inflater = (LayoutInflater) activity                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);    if (convertVIEw == null)        convertVIEw = inflater.inflate(R.layout.List_row, null);    if (imageLoader == null)        imageLoader = AppController.getInstance().getimageLoader();    NetworkImageVIEw thumbnail = (NetworkImageVIEw) convertVIEw            .findVIEwByID(R.ID.thumbnail);    TextVIEw Title = (TextVIEw) convertVIEw.findVIEwByID(R.ID.Title);    TextVIEw rating = (TextVIEw) convertVIEw.findVIEwByID(R.ID.rating);    TextVIEw genre = (TextVIEw) convertVIEw.findVIEwByID(R.ID.genre);    TextVIEw year = (TextVIEw) convertVIEw.findVIEwByID(R.ID.releaseYear);    // getting movIE data for the row    MovIE m = movIEItems.get(position);    // thumbnail image    thumbnail.setimageUrl(m.getthumbnailUrl(), imageLoader);    // Title    Title.setText(m.getTitle());    // rating    rating.setText("rating: " + String.valueOf(m.getrating()));    // genre    String genreStr = "";    for (String str : m.getGenre()) {        genreStr += str + ", ";    }    genreStr = genreStr.length() > 0 ? genreStr.substring(0,            genreStr.length() - 2) : genreStr;    genre.setText(genreStr);    // release year    year.setText(String.valueOf(m.getYear()));    return convertVIEw;}

}

和detail.xml

<?xml version="1.0" enCoding="utf-8"?><relativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"xmlns:tools="http://schemas.androID.com/tools"androID:layout_wIDth="wrap_content"androID:layout_height="match_parent"androID:background="#ffffff" >        <com.androID.volley.toolBox.NetworkImageVIEw    androID:ID="@+ID/thumbnail"     androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:layout_alignParenttop="true"    androID:layout_centerHorizontal="true"    androID:layout_margintop="42dp"    tools:ignore="ContentDescription"/>        <linearLayout    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    androID:gravity="center_horizontal"    androID:orIEntation="vertical" >        <TextVIEw        androID:ID="@+ID/name_label"        androID:layout_wIDth="fill_parent"        androID:layout_height="wrap_content"        androID:textSize="20sp"        androID:divIDer="@color/List_divIDer"        androID:divIDerHeight="1dp" />    </linearLayout>		 	</relativeLayout>

我是这方面的新手,因此我们将不胜感激.非常感谢！

解决方法:

干得好！！

内部MainActivity：

ListVIEw.setonItemClickListener(new AdapterVIEw.OnItemClickListener() {    @OverrIDe    public voID onItemClick(AdapterVIEw<?> parent, VIEw vIEw, int position, long ID) {        // your code        BitmapDrawable bd = (BitmapDrawable) ((NetworkImageVIEw) vIEw.findVIEwByID(R.ID.thumbnail))                .getDrawable();        Bitmap bitmap=bd.getBitmap();        ByteArrayOutputStream baos = new ByteArrayOutputStream();        bd.getBitmap().compress(Bitmap.CompressFormat.PNG, 100, baos);         byte[] imgByte = baos.toByteArray();        Intent intent = new Intent(MainActivity.this, Detail.class);        intent.putExtra("image", imgByte);        // any other extra you need to pass        startActivity(intent);    }}

内部细节：

Bundle extras = getIntent().getExtras();byte[] b = extras.getByteArray("image");Bitmap bmp = BitmapFactory.decodeByteArray(b, 0, b.length);BitmapDrawable background = new BitmapDrawable(bmp);findVIEwByID(R.ID.root_layout).setBackgroundDrawable(background);

内部detail.xml

为您的relativeLayout分配一个ID

< relativeLayout xmlns：androID =“ http://schemas.androID.com/apk/res/androID”
    androID：ID =“ @ ID / root_layout”
