NetworkImageView does not load the image the first time

I'm trying to load an image from my API to show it as a profile image, the problem is that the user opens the navigator for the first time, the image does not load, and this makes the whole layout disappear, but from the second time it all works, and I notice that this happens when the width of the image is less than the height. This is the class I'm using:

public class CircledNetworkImageView extends ImageView { public boolean mCircled; /** * The URL of the network image to load */ private String mUrl; /** * Resource ID of the image to be used as a placeholder until the network image is loaded. */ private int mDefaultImageId; /** * Resource ID of the image to be used if the network response fails. */ private int mErrorImageId; /** * Local copy of the ImageLoader. */ private ImageLoader mImageLoader; /** * Current ImageContainer. (either in-flight or finished) */ private ImageLoader.ImageContainer mImageContainer; public CircledNetworkImageView(Context context) { this(context, null); } public CircledNetworkImageView(Context context, AttributeSet attrs) { this(context, attrs, 0); } public CircledNetworkImageView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } /** * Sets URL of the image that should be loaded into this view. Note that calling this will * immediately either set the cached image (if available) or the default image specified by * {@link CircledNetworkImageView#setDefaultImageResId(int)} on the view. * <p/> * NOTE: If applicable, {@link CircledNetworkImageView#setDefaultImageResId(int)} and * {@link CircledNetworkImageView#setErrorImageResId(int)} should be called prior to calling * this function. * * @param url The URL that should be loaded into this ImageView. * @param imageLoader ImageLoader that will be used to make the request. */ public void setImageUrl(String url, ImageLoader imageLoader) { mUrl = url; mImageLoader = imageLoader; // The URL has potentially changed. See if we need to load it. loadImageIfNecessary(false); } /** * Sets the default image resource ID to be used for this view until the attempt to load it * completes. */ public void setDefaultImageResId(int defaultImage) { mDefaultImageId = defaultImage; } /** * Sets the error image resource ID to be used for this view in the event that the image * requested fails to load. */ public void setErrorImageResId(int errorImage) { mErrorImageId = errorImage; } /** * Loads the image for the view if it isn't already loaded. * * @param isInLayoutPass True if this was invoked from a layout pass, false otherwise. */ void loadImageIfNecessary(final boolean isInLayoutPass) { int width = getWidth(); int height = getHeight(); ScaleType scaleType = getScaleType(); boolean wrapWidth = false, wrapHeight = false; if (getLayoutParams() != null) { wrapWidth = getLayoutParams().width == ViewGroup.LayoutParams.WRAP_CONTENT; wrapHeight = getLayoutParams().height == ViewGroup.LayoutParams.WRAP_CONTENT; } // if the view bounds aren't known yet, and this is not a wrap-content/wrap-content // view, hold off on loading the image. boolean isFullyWrapContent = wrapWidth && wrapHeight; if (width == 0 && height == 0 && !isFullyWrapContent) { return; } // if the URL to be loaded in this view is empty, cancel any old requests and clear the // currently loaded image. if (TextUtils.isEmpty(mUrl)) { if (mImageContainer != null) { mImageContainer.cancelRequest(); mImageContainer = null; } setDefaultImageOrNull(); return; } // if there was an old request in this view, check if it needs to be canceled. if (mImageContainer != null && mImageContainer.getRequestUrl() != null) { if (mImageContainer.getRequestUrl().equals(mUrl)) { // if the request is from the same URL, return. return; } else { // if there is a pre-existing request, cancel it if it fetching a different URL. mImageContainer.cancelRequest(); setDefaultImageOrNull(); } } // Calculate the max image width / height to use while ignoring WRAP_CONTENT dimens. int maxWidth = wrapWidth ? 0 : width; int maxHeight = wrapHeight ? 0 : height; // The pre-existing content of this view didn't match the current URL. Load the new image // from the network. ImageLoader.ImageContainer newContainer = mImageLoader.get(mUrl, new ImageLoader.ImageListener() { @Override public void onErrorResponse(VolleyError error) { if (mErrorImageId != 0) { setImageResource(mErrorImageId); } } @Override public void onResponse(final ImageLoader.ImageContainer response, boolean isImmediate) { // If this was an immediate response that was delivered inside of a layout // pass do not set the image immediately as it will trigger a requestLayout // inside of a layout. Instead, defer setting the image by posting back to // the main thread. if (isImmediate && isInLayoutPass) { post(new Runnable() { @Override public void run() { onResponse(response, false); } }); return; } if (response.getBitmap() != null) { setImageBitmap(response.getBitmap()); } else if (mDefaultImageId != 0) { setImageResource(mDefaultImageId); } } }, maxWidth, maxHeight, scaleType); // update the ImageContainer to be the new bitmap container. mImageContainer = newContainer; } private void setDefaultImageOrNull() { if (mDefaultImageId != 0) { setImageResource(mDefaultImageId); } else { setImageBitmap(null); } } @Override protected void onLayout(boolean changed, int left, int top, int right, int bottom) { super.onLayout(changed, left, top, right, bottom); loadImageIfNecessary(true); } @Override protected void onDetachedFromWindow() { if (mImageContainer != null) { // If the view was bound to an image request, cancel it and clear // out the image from the view. mImageContainer.cancelRequest(); setImageBitmap(null); // also clear out the container so we can reload the image if necessary. mImageContainer = null; } super.onDetachedFromWindow(); } @Override protected void drawableStateChanged() { super.drawableStateChanged(); invalidate(); } /** * In case the bitmap is manually changed, we make sure to * circle it on the next onDraw */ @Override public void setImageBitmap(Bitmap bm) { mCircled = false; super.setImageBitmap(bm); } /** * In case the bitmap is manually changed, we make sure to * circle it on the next onDraw */ @Override public void setImageResource(int resId) { mCircled = false; super.setImageResource(resId); } /** * In case the bitmap is manually changed, we make sure to * circle it on the next onDraw */ @Override public void setImageDrawable(Drawable drawable) { mCircled = false; super.setImageDrawable(drawable); } /** * We want to make sure that the ImageView has the same height and width */ @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { Drawable drawable = getDrawable(); if (drawable != null) { int width = MeasureSpec.getSize(widthMeasureSpec); int diw = drawable.getIntrinsicWidth(); if (diw > 0) { int height = width * drawable.getIntrinsicHeight() / diw; setMeasuredDimension(width, height); } else super.onMeasure(widthMeasureSpec, heightMeasureSpec); } else super.onMeasure(widthMeasureSpec, heightMeasureSpec); } @Override protected void onDraw(Canvas canvas) { //Let circle the image if (!mCircled && getDrawable() != null) { Drawable d = getDrawable(); try { //We use reflection here in case that the drawable isn't a //BitmapDrawable but it contains a public getBitmap method.

I came up with this solution, but I did not like it, because the image loses its quality:

} }); profilePic.setImageUrl(GlobalModel.getPerfil().getIdDaImagem(), imageLoader); profilePic.setDefaultImageResId(R.drawable.avatar_); } @Override public void onActivityResult(final int requestCode, final int resultCode, final Intent data) { super.onActivityResult(requestCode, resultCode, data);

options.inSampleSize = 8; Bitmap photoGaleria = BitmapFactory.decodeFile(mImageCaptureUri.getPath(), options); photoGaleria = Bitmap.createScaledBitmap(photoGaleria, 200, 200, false); ByteArrayOutputStream bytesG = new ByteArrayOutputStream();

break; } } catch (Exception e) { e.printStackTrace(); } } private void previewCapturedImage(String path) { try { UploadFoto mUpload = new UploadFoto(path); mUpload.setEventoListener(new IExecutarTarefa<UploadFoto>() { @Override public void AntesDeExecutar(UploadFoto tarefa) { } @Override public void DepoisDeExecutar(UploadFoto tarefa) { if (tarefa.getResposta()[0].equals("200")) { GlobalModel.getPerfil().setIdDaImagem(WebService.imgURL + tarefa.getResposta()[1].replace("\"", "")); profilePic.setImageUrl(GlobalModel.getPerfil().getIdDaImagem(), imageLoader); } } }); mUpload.execute(); } catch (NullPointerException e) { e.printStackTrace(); } } @Override public void onBackPressed() { super.onBackPressed(); finish(); overridePendingTransition(R.anim.animation_back, R.anim.animation_back_leave); } @Override protected void onResume() { super.onResume(); CarregarPerfil mCarrega = new CarregarPerfil(); mCarrega.execute();

Since you did not post your activity that caused the navigation box, so I used in your project both your CircledNetworkImageView class and the built-in NetworkImageView . It works well. Please refer to the following:

CustomNavigationDrawer.java:

 public class CustomNavigationDrawer { private static ActionBarDrawerToggle sDrawerToggle; public static DrawerLayout setUpDrawer(final Context context) { final Activity activity = ((Activity) context); DrawerLayout sDrawerLayout = (DrawerLayout) activity.findViewById(R.id.drawer_layout); if (activity.getActionBar() != null) { activity.getActionBar().setDisplayHomeAsUpEnabled(true); activity.getActionBar().setHomeButtonEnabled(true); } sDrawerToggle = new ActionBarDrawerToggle( activity, sDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close ) { public void onDrawerClosed(View view) { activity.invalidateOptionsMenu(); syncState(); } public void onDrawerOpened(View drawerView) { activity.invalidateOptionsMenu(); syncState(); } }; sDrawerLayout.setDrawerListener(sDrawerToggle); return sDrawerLayout; } public static void syncState() { sDrawerToggle.syncState(); } public static void onConfigurationChanged(Configuration newConfig) { sDrawerToggle.onConfigurationChanged(newConfig); } } 

MainActivity.java:

 public class MainActivity extends Activity { final Context mContext = this; final String mUrl = "http://.../getimage"; NetworkImageView mNetworkImageView; CircledNetworkImageView mCircledNetworkImageView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); CustomNavigationDrawer.setUpDrawer(this); mNetworkImageView = (NetworkImageView) findViewById(R.id.networkImageView); mNetworkImageView.setImageUrl(mUrl, VolleySingleton.getInstance(mContext).getImageLoader()); mCircledNetworkImageView = (CircledNetworkImageView) findViewById(R.id.circleImageView); mCircledNetworkImageView.setImageUrl(mUrl, VolleySingleton.getInstance(mContext).getImageLoader()); } @Override protected void onPostCreate(Bundle savedInstanceState) { super.onPostCreate(savedInstanceState); CustomNavigationDrawer.syncState(); } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); CustomNavigationDrawer.onConfigurationChanged(newConfig); } @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu_main, menu); return true; } } 

activity_main.xml:

 <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".MainActivity"> <RelativeLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="start" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin"> <com.android.volley.toolbox.NetworkImageView android:id="@+id/networkImageView" android:layout_width="300dp" android:layout_height="wrap_content" /> <com.example.networkimageview.CircledNetworkImageView android:id="@+id/circleImageView" android:layout_width="200dp" android:layout_height="wrap_content" android:layout_below="@+id/networkImageView" /> </RelativeLayout> </android.support.v4.widget.DrawerLayout> 

You can create a new sample project and use my sample code. Hope this helps!

if (width == 0 && height == 0 && !isFullyWrapContent) {

I assume the first loadImage code will return due to this condition. Width and height are 0 before the entire success of loading the user interface. log before returning this condition. Hope this helps you.
