Load Image from sdcard
Description
We can Load Image from sdcard and use them in ImageView.
Example
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
/* w w w. j a v a 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 ava 2 s . 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") );
}
}
Example 2
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 . j a v a2 s . c om*/
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.
