I'm using Camera API and invoking the camera.
I want to display a header (for branding) on the top of the camera preview. The header is a jpeg image.
Is it possible? Any help appreciated.
Thanks in advance.
My code goes as below.
public class CameraActivity extends Activity {
@Override
protected void onPause() {
super.onPause();
}
private static final int CAMERA_PIC_REQUEST = 2500;
private Bitmap image2;
private Bitmap bm;
public static String imagepath;
public static int x=1;
private RdmsDbAdapter dbHelper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.header);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
//caling new incident
if(IncidentFormActivity.incident_id == null || IncidentFormActivity.isDisable==true){
//DBAdapter instance created and connection opened.
dbHelper = new RdmsDbAdapter(CameraActivity.this);
dbHelper.open();
//setting up flags
NewIncidentHelper nih = new NewIncidentHelper();
nih.setUpNewIncident();
//setting up incident_id
String Date= IncidentIdGenerator.getDate();
String Time = IncidentIdGenerator.getTime();
IncidentFormActivity.incident_id = IncidentIdGenerator.now("ddMMyyyyHHmmss");
dbHelper.executeSQL("insert into incident values ('" + IncidentFormActivity.incident_id
+ "', ' ', ' ', ' ', ' ', '"+Date+"', '0','0','0','0','0','0','0','0','0','"+Time+"')");
dbHelper.close();
}
//calling camera
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
//back key on phone pressed
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
Intent i= new Intent(CameraActivity.this, IncidentFormActivity.class);
startActivity(i);
this.finish();
break;
default:
break;
}
return super.onKeyDown(keyCode, event);
}
//handle response came from camera when the picture is taken.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST && resultCode == RESULT_OK) {
final ImageView img = new ImageView(this);
img.setLayoutParams(new LayoutParams(100, 100));
image2 = (Bitmap) data.getExtras().get("data");
img.setImageBitmap(image2);
String incident_ID = IncidentFormActivity.incident_id;
//l2.addView(img);
imagepath="/sdcard/RDMS/"+incident_ID+ x + ".png";
File file = new File(imagepath);
try {
bm = Bitmap.createScaledBitmap( image2,400, 300, true);
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bm.compress(CompressFormat.PNG, 90, ostream);
ostream.close();
//Initialising db class and inserting values
dbHelper = new RdmsDbAdapter(CameraActivity.this);
dbHelper.open();
dbHelper.executeSQL("insert into files values ('"+imagepath+"', '"+IncidentFormActivity.incident_id+"')");
dbHelper.close();
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),"yourfirst error message is "
+ e.toString(), 1000).show();
}
x++;
final AlertDialog.Builder alert = new AlertDialog.Builder(
CameraActivity.this);
alert.setTitle(getString(R.string.anotherimage));
alert.setCancelable(false);
//alert.setMessage("Play or Delete the Video selected");
//alert.setIcon(R.drawable.vid_red);
alert.setPositiveButton(getString(R.string.yes), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {

}
});

startActivity(callback);
}
});
alert.show();
}

{
