Android – Loading images using Glide in Imageview

androidandroid-glideimageview

I am using Glide library for loading images in imageview and using the below code.

Glide.with(mActivity)
                .load(img.getmGridViewImageUrl())
                .placeholder(R.color.grey_light)
                .into(imageHolder.imageView);

The placeholder with grey color gets visible until the image does not load but after the image get loads in imageview, the placeholder still take place and show some blank space after that image.

How can I resolve this issue. Please help me if you have any idea here.

Try this code.

When I give fix height to the ImageView it works for me.

Here's the layout

<ImageView 
    android:id="@+id/imgPoster"
    android:layout_width="fill_parent"
    android:layout_height="@dimen/height_of_getInspired_list"
    android:layout_centerVertical="true"
    android:scaleType="fitXY" 
    android:src="@drawable/default_image"/>

Here's my code.

Glide.with(this.context).load(inspiredList.get(position).image)
.error(R.drawable.default_image)
.centerCrop()
.crossFade()
.placeholder(R.drawable.default_image).into(holder.imgPoster);

Android – How to save an activity state using the save instance state

You need to override onSaveInstanceState(Bundle savedInstanceState) and write the application state values you want to change to the Bundle parameter like this:

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
  super.onSaveInstanceState(savedInstanceState);
  // Save UI state changes to the savedInstanceState.
  // This bundle will be passed to onCreate if the process is
  // killed and restarted.
  savedInstanceState.putBoolean("MyBoolean", true);
  savedInstanceState.putDouble("myDouble", 1.9);
  savedInstanceState.putInt("MyInt", 1);
  savedInstanceState.putString("MyString", "Welcome back to Android");
  // etc.
}

The Bundle is essentially a way of storing a NVP ("Name-Value Pair") map, and it will get passed in to onCreate() and also onRestoreInstanceState() where you would then extract the values from activity like this:

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
  super.onRestoreInstanceState(savedInstanceState);
  // Restore UI state from the savedInstanceState.
  // This bundle has also been passed to onCreate.
  boolean myBoolean = savedInstanceState.getBoolean("MyBoolean");
  double myDouble = savedInstanceState.getDouble("myDouble");
  int myInt = savedInstanceState.getInt("MyInt");
  String myString = savedInstanceState.getString("MyString");
}

Or from a fragment.

@Override
public void onViewStateRestored(@Nullable Bundle savedInstanceState) {
    super.onViewStateRestored(savedInstanceState);
    // Restore UI state from the savedInstanceState.
    // This bundle has also been passed to onCreate.
    boolean myBoolean = savedInstanceState.getBoolean("MyBoolean");
    double myDouble = savedInstanceState.getDouble("myDouble");
    int myInt = savedInstanceState.getInt("MyInt");
    String myString = savedInstanceState.getString("MyString");
}

You would usually use this technique to store instance values for your application (selections, unsaved text, etc.).
