How to retrieve data from the firebase and show inside the CardView nicely

I have created the CreateEvent.java module to upload the data to firebase. But how to retrieve the data and show in the Cardlist? For example show in the xml file below. And also if there was more than 1 data in firebase, how to show in with multiple cardlist that I have created in the xml file?

I did it by adding setZOrderOnTop(true) for the videoview to bring it front and it's working perfectly.

Share text and image with android intent

That is my code java
intent.putExtra(Intent.EXTRA_SUBJECT, "My App name and some text");
intent.putExtra(Intent.EXTRA_TEXT, "a link");
intent.putExtra(Intent.EXTRA_STREAM,getImageUri(context,mBitmap));
intent.setType("image/*,text/plain");
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
I want to share image and text. This code works on WhatsApp, Twitter, Gmail , etc .. but it does not work on Facebook
thank you in advance for your help

If you want to share the Image and text on Facebook without using Facebook SDK then you have to create the bitmap of your image plus text and then you can share that bitmap on facebook.
Download the source code from here (Share image and text on facebook using intent in android)

Thanks!

You can share int value of an image as R.drawable.image and get it with getResources.getDrawable(int)

picture returning to app is sideways

making a simple app, the problem I am having now is that when im using an intent to launch the camera app to take a picture, the app is supposed to take the picture and overwrite the imageview which was for the background image. What its doing is bring the freshly taken picture and displaying it sideways.
this is my main java file:
package com.example.piktuur;
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.provider.MediaStore;
import android.view.Menu;
import android.view.View;
import android.widget.ImageView;
import android.widget.SeekBar;
public class PiktuurMain extends Activity {
private Uri outputFileUri;
private static int TAKE_PICTURE = 1;
private ImageView image;
private SeekBar adjust;
public int height, width;
public boolean proceede;
public File file;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.piktuur_main);
image = (ImageView) findViewById(R.id.imageView1);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.piktuur_main, menu);
return true;
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == TAKE_PICTURE && resultCode == RESULT_OK) {
BitmapFactory.Options options = new BitmapFactory.Options();
String file = Environment.getExternalStorageDirectory() + "/image.png";
Bitmap bitmap = BitmapFactory.decodeFile(file, options);
image.setImageBitmap(bitmap);
}
}
public void cameraClicked(View V){
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(), "image.png");
outputFileUri = Uri.fromFile(file);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
startActivityForResult(intent, TAKE_PICTURE);
}
public void shareClicked(View V){
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, "stephen.w.protzman#gmail.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Piktuur");
intent.putExtra(Intent.EXTRA_TEXT, "Here is a picture for you!");
startActivity(Intent.createChooser(intent, "Send Email"));
}
}
and here is the main xml with the imageview in it:
<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"
tools:context=".PiktuurMain" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:scaleType="fitXY"
android:src="#drawable/pic" />
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_marginBottom="5dp" >
<ImageButton
android:id="#+id/takepic"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#drawable/round"
android:onClick="cameraClicked"
android:src="#android:drawable/ic_menu_camera" />
<ImageButton
android:id="#+id/editpic"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_marginLeft="15dp"
android:layout_marginRight="15dp"
android:layout_weight="1"
android:background="#drawable/round"
android:src="#android:drawable/ic_menu_edit" />
<ImageButton
android:id="#+id/sharepic"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#drawable/round"
android:onClick="shareClicked"
android:src="#android:drawable/ic_menu_share" />
</LinearLayout>
<SeekBar
android:id="#+id/seekBar1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/linearLayout1"
android:layout_alignParentLeft="true" />
</RelativeLayout>
I have zero ideas why this is happening any clue?

try this
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK)
{
Uri imageUri = data.getData();
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), imageUri);
image.setImageBitmap(bitmap);
}
}

Selecting image for imageview1 at left and imageview2 at right fixed

I'm still new here in android. Please help me. I manage to put the imageview to the left and right side of my Layout. My problem is when I select an image for imageview2 it passes the image to imageview1 and still the imageview2 can be seen from the right side.
I need to do is when I select an image for imageview2 it should be fixed at the right side. I think I have problems with my code in java?
Here is my code for xml.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/insert_bg"
>
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingTop="15dip"
android:paddingBottom="15dip"
>
<ImageView
android:id="#+id/img_left"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fitsSystemWindows="false"
android:scaleType="fitStart"
android:src="#drawable/insert_ci" />
<ImageView
android:id="#+id/img_center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="2"
android:fitsSystemWindows="false"
android:scaleType="fitEnd"
android:src="#drawable/insert_ci"
android:textAlignment="viewEnd" />
</LinearLayout>
And this code for java.

}
public void onActivityResult(int requestCode, int resultCode, Intent data)
{

{
//File folder = new File(Environment.getExternalStorageDirectory() + "/Database/");
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public void onActivityResult2(int requestCode, int resultCode, Intent data)

System.out.println("Image Path : " + selectedImagePath2);
img2.setImageURI(selectedImageUri);
}
}
}
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);
}
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
The problem that I was talking about is like this.http://imageshack.us/photo/my-images/31/6sa6.png/

Use this for two imageViews. So your images will not overlap
android:adjustViewBounds="true"
android:scaleType="fitXY

Try this one,
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
tools:context=".MainActivity" >
<ImageView
android:id="#+id/img_left"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fitsSystemWindows="false"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/img_center"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fitsSystemWindows="false"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher"
android:textAlignment="viewEnd" />
</LinearLayout>

The image is getting stretched because of the weight mentioned.
The android:layout_weight for the first imageView is 1 and that is for second imageView is 2.
This leads to taking 2/3rd of the screen by the the second imageView and the rest by the first.
Adjust the weights and you can overcome the issue.

Change your Imageview make 0dp to your android:layout_width#
<ImageView
android:id="#+id/img_left"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:fitsSystemWindows="false"
android:scaleType="fitStart"
android:src="#drawable/icon" />
<ImageView
android:id="#+id/img_center"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="2"
android:fitsSystemWindows="false"
android:scaleType="fitEnd"
android:src="#drawable/icon"
android:textAlignment="viewEnd" />
Update
Create one more folder named layout-land and keep same xml inside with appropriate changes, hope it works.
