Question

我正在尝试从listview中制作我的图像，但它没有发生..我最终获得这样的图像

但我希望我的listview图像像这样，

这是SumMenu活动：

public class SubMenu extends AppCompatActivity {

    JSONObject jsonobject;
    JSONArray jsonarray;
    ListView listview;
    ListViewAdapter adapter;
    ProgressDialog mProgressDialog;
    ArrayList<HashMap<String, String>> arraylist;
    static String RANK = "id";
    static String COUNTRY = "name";
    private ProgressDialog pDialog;
    String status="";
    static String FLAG = "image";
    Integer i = 1;
    String _stringVal;
    private ProgressDialog progress;
   /* final int Pizza = 0; //should be equal to the index in your array.
    final int Pasta = 1;
    final int Lasagna = 2;
    final int Salad =3 ;
    final int Breakfast = 4;
    final int Beverages= 5;
    final int Soup = 6;

    final int SpecialOffer =7;*/



    private static String url_create_book = "http://cloud....com/broccoli/creatinfo.php";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        setContentView(R.layout.activity_sub_menu);


        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        String SelectedId = getIntent().getStringExtra("id");


        getSupportActionBar().setDisplayHomeAsUpEnabled(true);


        // Get the view from listview_main.xml

        // Execute DownloadJSON AsyncTask
        new DownloadJSON().execute();
    }

    // DownloadJSON AsyncTask
    private class DownloadJSON extends AsyncTask<Void, Void, Void> implements AdapterView.OnItemClickListener, AdapterView.OnItemSelectedListener {

        // @Override
        //  protected void onPreExecute() {
        //  super.onPreExecute();
        // Create a progressdialog
        //   mProgressDialog = new ProgressDialog(SubMenu.this);
        // Set progressdialog title
        //   mProgressDialog.setTitle("Categories of Main categories.....");
        // Set progressdialog message
        //  mProgressDialog.setMessage("Loading...");
        //  mProgressDialog.setIndeterminate(false);
        // Show progressdialog
        //  mProgressDialog.show();
        // }

        @Override
        protected Void doInBackground(Void... params) {
            // Create an array
            arraylist = new ArrayList<HashMap<String, String>>();
            // Retrieve JSON Objects from the given URL address
            jsonarray = JsonFunctions
                    .getJSONfromURL("http://cloud..com/broccoli/menu_typeitem.php?id=" + getIntent().getStringExtra("id"));
            try {
                for (int i = 0; i < jsonarray.length(); i++) {
                    HashMap<String, String> map = new HashMap<String, String>();
                    jsonobject = jsonarray.getJSONObject(i);
                    map.put("name", jsonobject.getString("name"));
                    map.put("image", jsonobject.getString("image"));
                    // Set the JSON Objects into the array
                    arraylist.add(map);
                }
            } catch (JSONException e) {
                Log.e("Error", e.getMessage());
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(Void args) {
            // Locate the listview in listview_main.xml
            listview = (ListView) findViewById(R.id.list1);
            // Pass the results into ListViewAdapter.java
            adapter = new ListViewAdapter(SubMenu.this, arraylist);
            // Set the adapter to the ListView
            listview.setAdapter(adapter);
            listview.setOnItemClickListener(this);
            // Close the progressdialog
            // mProgressDialog.dismiss();
        }



        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long rowId) {
                                some coding....
                               }
        @Override
        public void onItemSelected(AdapterView<?> parent,
                                   View view, int pos, long id) {
            //  Toast.makeText(SubMenu.this,"The planet is " + parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show();
        }

        public void onNothingSelected(AdapterView parent) {
            // Do nothing.
        }
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case android.R.id.home:
                onBackPressed();
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }
}

这里是listview适配器：

public class ListViewAdapter extends BaseAdapter {

    // Declare Variables
    Context context;
    LayoutInflater inflater;
    ArrayList<HashMap<String, String>> data;
    ImageLoader imageLoader;
    HashMap<String, String> resultp = new HashMap<String, String>();

    public ListViewAdapter(Context context,
                           ArrayList<HashMap<String, String>> arraylist) {
        this.context = context;
        data = arraylist;
        imageLoader = new ImageLoader(context);
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    public View getView(final int position, View convertView, ViewGroup parent) {
        // Declare Variables
        TextView id;
        TextView name;
        TextView population;
        CircleImageView image;

        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View itemView = inflater.inflate(R.layout.list_item1, parent, false);
        // Get the position
        resultp = data.get(position);

        // Locate the TextViews in listview_item.xml
       // id = (TextView) itemView.findViewById(R.id.idq);
        name = (TextView) itemView.findViewById(R.id.type1);


        // Locate the ImageView in listview_item.xml
        image = (CircleImageView) itemView.findViewById(R.id.subimg);
      //  icon = (ImageView) itemView.findViewById(R.id.arrow);
        // Capture position and set results to the TextViews
      //  id.setText(resultp.get(SubMenu.RANK));
        name.setText(resultp.get(SubMenu.COUNTRY));

        // Capture position and set results to the ImageView
        // Passes flag images URL into ImageLoader.class
        imageLoader.DisplayImage(resultp.get(SubMenu.FLAG), image);
      //  imageLoader.DisplayImage(resultp.get(SubMenu.FLAG), icon);
        // Capture ListView item click
        /**itemView.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
        // Get the position
        resultp = data.get(position);
        Intent intent = new Intent(context, SingleItemView.class);
        // Pass all data rank
        intent.putExtra("rank", resultp.get(MainActivity.RANK));
        // Pass all data country
        intent.putExtra("country", resultp.get(MainActivity.COUNTRY));
        // Pass all data population
        intent.putExtra("population",resultp.get(MainActivity.POPULATION));
        // Pass all data flag
        intent.putExtra("flag", resultp.get(MainActivity.FLAG));
        // Start SingleItemView Class
        context.startActivity(intent);

        }
        });*/
        return itemView;
    }
}

这是我的ImageLoader ..

这是我的list_item1.xml

<?xml version="1.0" encoding="utf-8"?>

        android:layout_height="wrap_content"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:layout_alignParentLeft="true"
        android:background="@color/colorwhite"
        android:padding="1dp" />

    <TextView
        android:id="@+id/type1"

        android:layout_weight="3"
        android:src="@drawable/dropdown" />


</LinearLayout>

我尝试了circleImage视图，并在我的gradle中添加了库..

compile 'de.hdodenhof:circleimageview:2.1.0'

我也没有获得固定加号图像......该怎么办？

在@sneha代码之后我得到这样的...如何以正确的方式修复同一行..

Answer 1

尝试像这样修改你的xml

   <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    >

    <!-- Product id (pid) - will be DDEN - used to pass to other activity -->


    <de.hdodenhof.circleimageview.CircleImageView
        android:id="@+id/subimg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:layout_alignParentLeft="true"
        android:background="@color/colorwhite"
        android:padding="1dp" />

    <TextView
        android:id="@+id/type1"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:textSize="20sp"
        android:gravity="center"
        android:layout_weight="1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <ImageView
        android:id="@+id/plus"
        android:layout_width="wrap_content"
        android:layout_height="15dp"
        android:layout_gravity="center"
        android:src="@drawable/dropdown" />


</LinearLayout>

用于圆形图像视图，见下文

尝试使用

 compile 'com.makeramen:roundedimageview:2.3.0'

This图书馆

 <com.makeramen.roundedimageview.RoundedImageView
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/imageView1"
    android:src="@drawable/photo1"
    android:scaleType="fitCenter"
    app:riv_corner_radius="30dip"
    app:riv_border_width="2dip"
    app:riv_border_color="#333333"
    app:riv_mutate_background="true"
    app:riv_tile_mode="repeat"
    app:riv_oval="true" />

或者您可以看到此question

Answer 2

问题此处

   android:layout_width="wrap_content"
    android:layout_height="wrap_content"

对于@ + id / plus删除

 android:layout_weight

您应该将硬编码尺寸尊重设置为库

<de.hdodenhof.circleimageview.CircleImageView
   xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/subimg"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:paddingTop="10dp"
    android:paddingBottom="10dp"
    android:layout_alignParentLeft="true"
    android:background="@color/colorwhite"
    android:padding="1dp" />

Answer 3

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <!-- Product id (pid) - will be DDEN - used to pass to other activity -->


    <de.hdodenhof.circleimageview.CircleImageView
        android:id="@+id/subimg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_margin="10dp"
        android:padding="5dp" />

    <TextView
        android:id="@+id/type1"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:layout_gravity="center_vertical"
        android:textSize="20sp" />

    <ImageView
        android:id="@+id/plus"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:src="@drawable/plus_image" />


</LinearLayout>

试试这段代码。要添加固定加图像，请在drawable文件夹中设置名为“plus_image”的加号图像。并将圆形图像设置为src

第一个选项是----使用circleimageview类

public class CircleImageView extends NetworkImageView {

    private static final ScaleType SCALE_TYPE = ScaleType.CENTER_CROP;

    private static final Bitmap.Config BITMAP_CONFIG = Bitmap.Config.ARGB_8888;

    private static final int DEFAULT_BORDER_WIDTH = 0;
    private static final int DEFAULT_BORDER_COLOR = Color.BLACK;
    private static final boolean DEFAULT_BORDER_OVERLAY = false;

    private final RectF mDrawableRect = new RectF();
    private final RectF mBorderRect = new RectF();

    private final Matrix mShaderMatrix = new Matrix();
    private final Paint mBitmapPaint = new Paint();
    private final Paint mBorderPaint = new Paint();

    private int mBorderColor = DEFAULT_BORDER_COLOR;
    private int mBorderWidth = DEFAULT_BORDER_WIDTH;

    private Bitmap mBitmap;
    private BitmapShader mBitmapShader;
    private int mBitmapWidth;
    private int mBitmapHeight;

    private float mDrawableRadius;
    private float mBorderRadius;

    private ColorFilter mColorFilter;

    private boolean mReady;
    private boolean mSetupPending;
    private boolean mBorderOverlay;

    public CircleImageView(Context context) {
    super(context);

    init();

xml文件中的

使用此imageview ---

<Your_package_name.CircleImageView
        android:id="@+id/marker_image"
        android:layout_width="35dp"
        android:layout_height="35dp"
        android:layout_gravity="center"
        android:scaleType="centerCrop"
        android:src="@drawable/ic_user_default
        android:visibility="visible"
        app:civ_border_width="2dp"
        app:civ_border_color="@android:color/transparent"
        />

在attrs.xml档案

中定义此属性

 <declare-styleable name="CircleImageView">
    <attr name="civ_border_width" format="dimension" />
    <attr name="civ_border_color" format="color" />
    <attr name="civ_border_overlay" format="boolean" />
    <attr name="civ_fill_color" format="color" />
</declare-styleable>

第二个选项是，如果您从服务器加载图像使用Glide库

Glide.with(this)
     .load(url)
     .placeholder(R.drawable.ic_user_default)
     .error(R.drawable.ic_user_default)
     .bitmapTransform(new CropCircleTransformation(this))
     .into(imageview);

我没有评论权利所以我在我的回答中编辑

----你必须按照滑动链接并按照其步骤...然后在适配器中你必须替换你的旧代码

imageLoader.DisplayImage(resultp.get(SubMenu.FLAG), image);

与

   Glide.with(this)
     .load(resultp.get(SubMenu.FLAG))
     .placeholder(R.drawable.ic_user_default)
     .error(R.drawable.ic_user_default)
     .bitmapTransform(new CropCircleTransformation(this))
     .into(image);

试试这个，希望它会对你有帮助。

您可以使用xml以循环格式显示图像。卡片视图将是您的完美解决方案。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    >

    <!-- Product id (pid) - will be DDEN - used to pass to other activity -->
 <android.support.v7.widget.CardView
      android:layout_width="80dp"
      android:layout_height="80dp"
      android:elevation="12dp"
      android:id="@+id/view2"
      app:cardCornerRadius="40dp"
      android:layout_centerHorizontal="true"
      android:innerRadius="0dp"
      app:cardBackgroundColor="#fff"
      android:shape="ring"
      android:thicknessRatio="1.9">

    <ImageView
        android:id="@+id/subimg"
        android:layout_width="match_parent"

        android:src="@drawable/ic_menu_share"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
       >
    </ImageView>
  </android.support.v7.widget.CardView>

    <TextView
        android:id="@+id/type1"
        android:paddingTop="10dp"
        android:paddingBottom="10dp"
        android:textSize="20sp"
        android:gravity="center"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
    <ImageView
        android:id="@+id/plus"
        android:layout_width="match_parent"
        android:layout_height="15dp"
        android:layout_gravity="center"
        android:layout_weight="3"
        android:src="@drawable/dropdown" />
