Android code for selecting pic from gallery or camera through intent

STEP 1:Create activity_pic.xml in layout res/layout folder

activity_pic.xml

<?xml version="1.0" encoding="utf-8"?> <RelativeLayout  xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:paddingBottom="@dimen/activity_vertical_margin" /> <Button android:text="@string/hello_world" android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/intent" /> <ImageView android:layout_width="150dp" android:layout_height="150dp" android:id="@+id/intentimage" android:layout_below="@+id/intent" android:background="@drawable/about" /><!--select any  image from drawable folder-->     </RelativeLayout>

Step 2 : add permission in AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.picactivitypro"> <uses-feature android:name="android.hardware.camera" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> </manifest>

Step 3 :Create file Pictureselect.java in main/java folder

Pictureselect.java

public class Pictureselect.java extends AppCompatActivity{         Button intentes;         ImageView images; final int TAKE_PICTURE=1; @Override protected void onCreate(Bundle savedInstanceState){         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_pic);         images=(ImageView)findViewById(R.id.intentimage);         intentes=(Button)findViewById(R.id.intent);         intentes.setOnClickListener(new View.OnClickListener(){ @Override public void onClick(View v)         {         selectImage();         }         });         }         } private void selectImage(){ final CharSequence[]options={"Take pic","Choose pic  from Gallery","Cancel"};         AlertDialog.Builder builder=new AlertDialog.Builder(trail.this);         builder.setTitle("Add Photo!");         builder.setItems(options,new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog,int item){         if(options[item].equals("Take Photo"))         {         Intent cameraIntent=new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);         startActivityForResult(cameraIntent,TAKE_PICTURE);         }         else if(options[item].equals("Choose from Gallery"))         {         Intent intent=new Intent(Intent.ACTION_PICK,         android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);         startActivityForResult(intent,2);         }         else if(options[item].equals("Cancel")){         dialog.dismiss();         }         }         });         builder.show();         } @Override protected void onActivityResult(int requestCode,int resultCode,Intent data){         super.onActivityResult(requestCode,resultCode,data);         if(resultCode==RESULT_OK){         if(requestCode==1){         Bitmap photo=(Bitmap)data.getExtras().get("data");         images.setImageBitmap(photo);         }         }         else if(requestCode==2)         {         Uri selectedImage=data.getData();         String[]filePath={MediaStore.Images.Media.DATA};         Cursor c=getContentResolver().query(selectedImage,filePath,null,null,null);         c.moveToFirst();         int columnIndex=c.getColumnIndex(filePath[0]);         String picturePath=c.getString(columnIndex);         c.close();         Bitmap thumbnail=(BitmapFactory.decodeFile(picturePath));         images.setImageBitmap(thumbnail);         }         }         }
