We can Load Image from sdcard and use them in ImageView
.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> // ww w. ja va 2 s .com <ImageView android:id="@+id/image3" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
The following Java code sets the image from resource.
package com.java2s.app; // ww w . j a va 2s.c o m import android.app.Activity; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.widget.ImageView; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ImageView imgView = (ImageView)findViewById(R.id.image3); imgView.setImageDrawable(Drawable.createFromPath("/mnt/sdcard/myImage.jpg") ); } }
The following setter method takes the URI of an image file and uses that as the image source.
package com.java2s.app; /*w w w . ja v a2 s .c o m*/ import android.app.Activity; import android.net.Uri; import android.os.Bundle; import android.widget.ImageView; public class MainActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ImageView imgView = (ImageView) findViewById(R.id.image3); imgView.setImageURI(Uri.parse("file://mnt/sdcard/myImage.jpg")); } }
This method is really only intended to be used for local images on the device, not for images that you might find through HTTP.
To use Internet-based images as the source for your
ImageView
, you'd most likely use BitmapFactory
and an InputStream
.
