The main goal of this Article is how to take photo /picture/image from the camera or gallery in your Android phone. First; user having two choice – take photo from camera and Choose from library; the user will need to choose any one option from list. Then depending on the option chosen by the user, we will either open the gallery or capture an image from the camera.
follow below steps:
Step 1: Create Layout File in CameraPhotoCapture Project.
Layout File
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="10dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:padding="5dp" >
<Button
android:id="@+id/btnSelectPhoto"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Select Photo" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="10dp" >
<ImageView
android:id="@+id/ivImage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="@drawable/ic_launcher" />
</LinearLayout>
</LinearLayout>
Step 2: Create new method into Main Activity File called “selectImage()”. It is used for to choose any one option from Camera, Gallery and Cancel in Alert dialog box.
select image method
private void selectImage() {
final CharSequence[] items = { "Take Photo", "Choose from Library",
"Cancel" };
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle("Add Photo!");
builder.setItems(items, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
if (items[item].equals("Take Photo")) {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File f = new File(android.os.Environment
.getExternalStorageDirectory(), "temp.jpg");
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
startActivityForResult(intent, REQUEST_CAMERA);
} else if (items[item].equals("Choose from Library")) {
Intent intent = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(
Intent.createChooser(intent, "Select File"),
SELECT_FILE);
} else if (items[item].equals("Cancel")) {
dialog.dismiss();
}
}
});
builder.show();
}
Step 3: Now we need return back to our activity with proper Result. So add “onActivityResult” method into Main activity class.
onActivity Result
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
File f = new File(Environment.getExternalStorageDirectory()
.toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bm;
BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
bm = BitmapFactory.decodeFile(f.getAbsolutePath(),
btmapOptions);
// bm = Bitmap.createScaledBitmap(bm, 70, 70, true);
ivImage.setImageBitmap(bm);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
f.delete();
OutputStream fOut = null;
File file = new File(path, String.valueOf(System
.currentTimeMillis()) + ".jpg");
try {
fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
if (requestCode == REQUEST_CAMERA) {
File f = new File(Environment.getExternalStorageDirectory()
.toString());
for (File temp : f.listFiles()) {
if (temp.getName().equals("temp.jpg")) {
f = temp;
break;
}
}
try {
Bitmap bm;
BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
bm = BitmapFactory.decodeFile(f.getAbsolutePath(),
btmapOptions);
// bm = Bitmap.createScaledBitmap(bm, 70, 70, true);
ivImage.setImageBitmap(bm);
String path = android.os.Environment
.getExternalStorageDirectory()
+ File.separator
+ "Phoenix" + File.separator + "default";
f.delete();
OutputStream fOut = null;
File file = new File(path, String.valueOf(System
.currentTimeMillis()) + ".jpg");
try {
fOut = new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (requestCode == SELECT_FILE) {
Uri selectedImageUri = data.getData();
String tempPath = getPath(selectedImageUri, MainActivity.this);
Bitmap bm;
BitmapFactory.Options btmapOptions = new BitmapFactory.Options();
bm = BitmapFactory.decodeFile(tempPath, btmapOptions);
ivImage.setImageBitmap(bm);
}
}
}
And Also add this method which is used into “onActivityResult” method.
getPath
public String getPath(Uri uri, Activity activity) {
String[] projection = { MediaColumns.DATA };
Cursor cursor = activity
.managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
