Android Imageview Display in RoundedShape?

This code is used to how Display  profile image in rounded shape  in Android,


/**
 * This class is used to create rounded image
 *
 */
public class RoundedImageView extends ImageView {
public RoundedImageView(Context context) {
super(context);
//   Auto-generated constructor stub
}

public RoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}

public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
protected void onDraw(Canvas canvas) {
    Drawable drawable = getDrawable();
    if (drawable == null) {
        return;
    }
    if (getWidth() == 0 || getHeight() == 0) {
        return;
    }
    Bitmap bitmapCommon = ((BitmapDrawable) drawable).getBitmap();
    if (bitmapCommon == null) {
        Log.d("null", "yes");
    } else {
        Log.d("not null", "yes");
    }
     bitmapCommon = bitmapCommon.copy(Bitmap.Config.ARGB_8888, true);
    int w = getWidth();
    bitmapCommon = getCroppedBitmap(bitmapCommon, w);
    canvas.drawBitmap(bitmapCommon, 0, 0, null);
}

public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius)
sbmp = Bitmap.createScaledBitmap(bmp, radius, radius, false);
else
sbmp = bmp;
Bitmap output = Bitmap.createBitmap(sbmp.getWidth(), sbmp.getHeight(),Config.ARGB_8888);
Canvas canvas = new Canvas(output);

final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, sbmp.getWidth(), sbmp.getHeight());

paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(sbmp.getWidth() / 2 + 0.7f,
sbmp.getHeight() / 2 + 0.7f, sbmp.getWidth() / 2 + 0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}
 and your xml file create like this

<com.packagename.RoundedImageView
                android:id="@+id/user_img"
                android:layout_width="60dip"
                android:layout_height="60dip"
                android:layout_gravity="center"
                android:background="@drawable/ic_launcher" />

Android Json parsing Example with listview?



The process of parsing JSON in Android is pretty simple, thankfully. We'll be using JSONObject for all the parsing goodness - there are also some other JSON classes, but we'll just go through the basic ones to give you a general idea of how it works.

Activity.Java
public class AndroidJSONParsingActivity extends Activity {
private ProgressDialog dialog;
private String string,id,name,mail;  
private ListView listview;
private ArrayList<SearchParent> arrayParents;
//private ArrayList<String> arrayChildren; 

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
dialog = new ProgressDialog(this);
string = "http://api.androidhive.info/contacts/";
 
listview = (ListView) findViewById(R.id.listView);
listview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) {
//   Auto-generated method stub
Object  ob = (Object) view.getTag();  
if(ob != null) {
TotalhistoryInfo parent = (TotalhistoryInfo) view.getTag();  
String name = parent.getPage_name();  
String mail = parent.getPage_date();
String ID = parent.getId();
Log.i("details=>", ID + name + mail);  
}
}
});
new uploadaudio().execute();
}
private void ProgressBar_show() {

((ProgressDialog) dialog).setTitle("JsonParsing");  
((ProgressDialog) dialog).setMessage("Your content is loading.. \nPlease wait..");
((ProgressDialog) dialog).setIndeterminate(true);
dialog.setCancelable(false);
dialog.show();
}

private void ProgressBar_hide() {
dialog.dismiss();
}
class uploadaudio extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
super.onPreExecute();
ProgressBar_show();
}

@Override
protected String doInBackground(String... params) {
load_JsonSections();
return null;
}
@SuppressLint("SetJavaScriptEnabled")
protected void onPostExecute(String result) {  
super.onPostExecute(result);
 
Log.i("onPostExecute==> ", arrayParents.toString());
AddedHistoryAdapter adapter = new AddedHistoryAdapter(AndroidJSONParsingActivity.this, R.layout.row_acc_info, arrayParents );   
listview.setAdapter(adapter); 
ProgressBar_hide();  
}
}
  
private void load_JsonSections() {
arrayParents = new ArrayList<SearchParent>();  
HttpClient httpclient = new DefaultHttpClient();
HttpGet httpget = new HttpGet(string);
HttpResponse response;
try {
response = httpclient.execute(httpget);  
HttpEntity entity = response.getEntity();  

if (entity != null) {

InputStream instream = entity.getContent();
String result = convertStreamToString(instream);
JSONObject json = new JSONObject(result);
 
JSONArray jsonOnb = json.getJSONArray("contacts");  
for (int i = 0; i < jsonOnb.length(); i++) {
JSONObject _Jsonquery = jsonOnb.getJSONObject(i);  

if (_Jsonquery.has("id")) {
 
id = _Jsonquery.getString("id");
name = _Jsonquery.getString("name");
mail = _Jsonquery.getString("email");  
arrayParents.add(new SearchParent(name, mail, id));  
}  
}
instream.close();
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (JSONException e) {
e.printStackTrace();
}
}

private String convertStreamToString(InputStream is) {

BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();

String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
is.close();
} catch (IOException e) {
e.printStackTrace();
}
}
return sb.toString();
}
}

AdapterActivity.java
public class AddedHistoryAdapter extends ArrayAdapter<SearchParent> {
//private final static String TAG = AccountsAdapter.class.getSimpleName();
private ArrayList<SearchParent> _valu;

}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
//View view = convertView;

total_acc.setPage_name(name);
total_acc.setPage_date(date);
total_acc.setId(ID);
convertView.setTag(total_acc);  
return (convertView);
}  
}

SearchParent.java
public class SearchParent {  
private String Id;
