Package Com.example;import Java.io.file;import Android.app.activity;import android.content.intent;import Android.graphics.bitmap;import Android.graphics.bitmapfactory;import Android.net.uri;import Android.os.Bundle; Import Android.os.environment;import Android.view.display;import Android.view.view;import Android.view.view.onclicklistener;import Android.widget.button;import Android.widget.imageview;public Class Mainactivity extends Activity {final static int camera_result = 0;imageview IMV; Button but; @Overrideprotected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (R.layout.fragment_main); Findviewbyid ();

But.setonclicklistener (New Onclicklistener () {public void OnClick (View v) {

                               /* Perform camera built-in camera intent */intent i = new Intent (Android.provider.MediaStore.ACTION_IMAGE_CAPTURE); Startactivityforresult ( I, Camera_result);}});} private void Findviewbyid () {but = (Button) Findviewbyid (r.id.but); IMV = (ImageView) Findviewbyid (r.id.img);}        /* When the activity is finished, the photo is displayed */

@Overrideprotected void Onactivityresult (int requestcode, int resultcode, Intent data) {Super.onactivityresult ( Requestcode, ResultCode, data); if (ResultCode = = RESULT_OK) {Bundle bundle = Data.getextras (); Bitmap bmp = (Bitmap) bundle.get ("Data"); Imv.setimagebitmap (BMP);}}
