Display images stored in cache, Android

Question

I download pictures from the Web and I stored them in the cache. Now, how I can display the photo in the XML. The photos stored as follwing:

/data/data/com.example.app/cache/wpta_i.jpeg

Changes according to the position. My XML is as following:

 <LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <ImageView
      android:id="@+id/img"  
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_gravity="center">      
    </ImageView>
  </LinearLayout>

How can I load the image from the cache and display it?

Answer 1

You should load the drawable from code and then setImageDrawable to the ImageView.

String pathName = "/data/data/com.example.app/cache/wpta_i.jpeg"; 
Drawable d = Drawable.createFromPath(pathName);
ImageView myImageView=(ImageView)findViewById(R.id.img);
myImageView.setImageDrawable(d);
