Have a look at the <a href="http://developer.android.com/reference/android/widget/ImageView.html">ImageView API</a>. There are several <code>setImage*</code> methods. Which one to use depends on the image you provide. If you have the image as resource (e.g. file res/drawable/my_image.png)

<pre><code>ImageView img = new ImageView(this); // or (ImageView) findViewById(R.id.myImageView);
img.setImageResource(R.drawable.my_image);

If you created imageview using xml file then follow the steps.

Solution 1: 

Step 1: Create an XML file



<pre><code>&lt;LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:background="#cc8181"
 &gt;

 &lt;ImageView
 android:id="@+id/image"
 android:layout_width="50dip"
 android:layout_height="fill_parent" 
 android:src="@drawable/icon"
 android:layout_marginLeft="3dip"
 android:scaleType="center"/&gt;

&lt;/LinearLayout&gt;
</code></pre>

Step 2: create an Activity 

<pre><code>ImageView img= (ImageView) findViewById(R.id.image);
img.setImageResource(R.drawable.my_image);
</code></pre>

Solution 2:

If you created imageview from Java Class

<pre><code>ImageView img = new ImageView(this);
img.setImageResource(R.drawable.my_image);
</code></pre>

blocks|key|992071|text|稍微深入一点，您也可以直接设置位图，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|992072|ImageView+imageView+=+new+ImageView(this);++
Bitmap+bImage+=+BitmapFactory.decodeResource(this.getResources(),+R.drawable.my_image);
imageView.setImageBitmap(bImage);|code-block|syntax|javascript|992073|当然，只有当您需要更改图像时，此技术才有用。|992074|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

Just to go a little bit further in the matter, you can also set a bitmap directly, like this: 

<pre><code>ImageView imageView = new ImageView(this); 
Bitmap bImage = BitmapFactory.decodeResource(this.getResources(), R.drawable.my_image);
imageView.setImageBitmap(bImage);
</code></pre>

Of course, this technique is only useful if you need to change the image.

blocks|key|777750|text|if+(android.os.Build.VERSION.SDK_INT+>=+21)+{
++++++++++++storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position],+context.getTheme()));

<pre><code>if (android.os.Build.VERSION.SDK_INT &gt;= 21) {
 storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position], context.getTheme()));
} else {
 storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position]));
}
</code></pre>

I have just started learning android. And i don't know How can I change the image of an <code>ImageView</code>? ie it has some Image which was set in the layout but i want to change that image through coding how should i do it ?

Here is the xml file

<pre><code>&lt;LinearLayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:background="#cc8181"
 &gt;

&lt;ImageView
 android:id="@+id/image"
 android:layout_width="50dip"
 android:layout_height="fill_parent" 
 android:src="@drawable/icon"
 android:layout_marginLeft="3dip"
 android:scaleType="center"/&gt;
</code></pre>



thanks for replying.
