Stuck on the usage of Intent

I am trying to pass the image I pick from gallery to another activity. Beside this, in same class, i have several editText to get data from user. To take data from editText and pass on SecondActivity i use Intent:

save=(Button)findViewById(R.id.save);
save.setOnClickListener(new View.OnClickListener() {

    @Override   
    public void onClick(View v) {

    Intent intent = new Intent(NewCard.this, Template.class);

            intent.putExtra("name", Name);
            intent.putExtra("company", Company);
            intent.putExtra("phone", Phone);
            intent.putExtra("mobile", Mobile);
            intent.putExtra("address", Address);
            intent.putExtra("email", Email);
            intent.putExtra("website", Website);
            intent.putExtra("title", Title); 

            startActivity(intent);

        }
    });

And in order i have 'SwitchCase' 'onActivityResult' where i use for picking image and set on imageView on FirstActivity. This is openGallery intent for double onActivityResult:

private void openGallerylogo() {
    // TODO Auto-generated method stub
    Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, 1);
}
private void openGalleryqr() {
    // TODO Auto-generated method stub
    Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
    photoPickerIntent.setType("image/*");
    startActivityForResult(photoPickerIntent, 2);
}

SwitchCase onActivityResult:

@Override
protected void onActivityResult(int requestCode, int resultcode, Intent data){
    super.onActivityResult(requestCode, resultcode, data);

    switch(1){
    case 1:

    if (requestCode == 1) 
    {
        if (data != null && resultcode == RESULT_OK) 
        {              

            Uri selectedImage = data.getData();

            String[] filePathColumn = {MediaStore.Images.Media.DATA};
            Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            String PicPath1 = cursor.getString(columnIndex);
            cursor.close();

    logoview.setBackgroundResource(0);
    logoview.setImageBitmap(BitmapFactory.decodeFile(PicPath1));

    break;
        }}  


    case 2:
        if (requestCode == 2) 
        {
            if (data != null && resultcode == RESULT_OK) 
            {              

                Uri selectedImage = data.getData();                     
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                cursor.moveToFirst();                   
                String PicPath2 = cursor.getString(columnIndex);
                cursor.close();
    qrcodeview.setBackgroundResource(0);
    qrcodeview.setImageBitmap(BitmapFactory.decodeFile(PicPath2));
    break;
}}

    }

    }

So now main thing is where to insert below code:

    final Intent newdata = new Intent(NewCard.this, Template.class);
    newdata.putExtra("picture_path1", PicPath1);
    newdata.putExtra("picture_path2", PicPath2);
    startActivity(newdata);

Normally, i have to insert in body of save.setOnClickListener and get data+images to pass SecondActivity as i do for editText. But i have clash for Second Intent.

Or I can insert as:

logoview.setBackgroundResource(0);
logoview.setImageBitmap(BitmapFactory.decodeFile(PicPath1));
Intent newdata = new Intent(NewCard.this, Template.class);
newdata.putExtra("picture_path1", PicPath1);

startActivity(newdata);

Then it works but intent starts immediately and i am unable to setText above. Thank you for your helps.

This is all my code in the class:

package com.example.mapcard;

public class NewCard extends Activity {

ImageView logoview,qrcodeview, location;
Bitmap bmp1,bmp2;
Button save,clear;
public String count="logo";

public String filename = "Mapcard.csv";
//  public String fileContent;

ReadCSV csv;
StringBuffer filePath;
//String picPath1;
File file;

public final static String EXTRA_MESSAGE = "com.example.mapcard.MESSAGE";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_new_card);

   filePath.append("/sdcard/Android/data/");
    //filePath.append(Environment.getExternalStorageDirectory().getPath()+"/Android/data/com.example.mapcard/Mapcard/BusinessCard/");
    file = new File(filePath+filename.toString());

    csv = new ReadCSV(file);

    save=(Button)findViewById(R.id.save);
    save.setOnClickListener(new View.OnClickListener() {

            csv.writeHeader(txtName.getText().toString()+ ","

Just store the picpaths as instance variables to your activity. Manage them like any other lifecyled instance variable (via onSaveInstanceState(), and onCreate(Bundle)) and have your onClickListener reference them there.

String mPicPath1, mPicPath2;

protected void onCreate(Bundle icicle) {

   mPicPath1 = null;
   mPicPath2 = null; // or restore these from the icicle Bundle
   ...
}

@Override
protected void onActivityResult(int requestCode, int resultcode, Intent data){
    super.onActivityResult(requestCode, resultcode, data);

    switch(requestCode){
    case 1:
        if (data != null && resultcode == RESULT_OK) 
        {              

            Uri selectedImage = data.getData();

            String[] filePathColumn = {MediaStore.Images.Media.DATA};
            Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
            cursor.moveToFirst();
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            mPicPath1 = cursor.getString(columnIndex);
            cursor.close();

            logoview.setBackgroundResource(0);
            logoview.setImageBitmap(BitmapFactory.decodeFile(mPicPath1));
        }
    break;  
    case 2:
        if (data != null && resultcode == RESULT_OK) 
        {              

            Uri selectedImage = data.getData();                     
            String[] filePathColumn = {MediaStore.Images.Media.DATA};
            Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            cursor.moveToFirst();                   
            mPicPath2 = cursor.getString(columnIndex);
            cursor.close();
            qrcodeview.setBackgroundResource(0);
            qrcodeview.setImageBitmap(BitmapFactory.decodeFile(mPicPath2));
        }
    break;
    }
    View saveButton = findViewById(R.id.save);
    // If the image paths are required before the activity can be started you can do this
    if (saveButton != null) {
       saveButton.setEnabled( !TextUtils.isEmpty(mPicPath1) &&  !TextUtils.isEmpty(mPicPath2));
    }
}

Then in your save button part:

save=(Button)findViewById(R.id.save);
save.setOnClickListener(new View.OnClickListener() {

@Override   
public void onClick(View v) {

Intent intent = new Intent(NewCard.this, Template.class);

        intent.putExtra("name", Name);
        intent.putExtra("company", Company);
        intent.putExtra("phone", Phone);
        intent.putExtra("mobile", Mobile);
        intent.putExtra("address", Address);
        intent.putExtra("email", Email);
        intent.putExtra("website", Website);
        intent.putExtra("title", Title); 
        // Add your picture paths if they are appropriate
        if (!TextUtils.isEmpty(mPicPath1)) {
            intent.putExtra("picture_path1", PicPath1);
        }
        if (!TextUtils.isEmpty(mPicPath2)) {
           intent.putExtra("picture_path2", PicPath2);
        }
        startActivity(intent);

    }
});
