Question:
In my app, I have two imageViews that are the same size and both work fine. However, when I put a picture into each imageView and then try to switch out the top imageView with a different picture, the bottom imageView ends up getting the picture that is supposed to go in the top imageView. I'm not sure why this is. Here is my xml file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/personalizetextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/customize"
android:textSize="30sp"
android:gravity="center"
android:layout_marginTop="20dip"/>
<TextView
android:id="@+id/personalizetextviewChangeBackground"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/customizebackground"
android:gravity="center" />
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:maxWidth="100dp"
android:maxHeight="100dp"
android:scaleType="fitCenter"
android:contentDescription="@string/descForBackground"
/>
<Button
android:id="@+id/btnChangeImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/change_background" />
<TextView
android:id="@+id/personalizetextviewChangeIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/change_icon"
android:gravity="center" />
<ImageView
android:id="@+id/imageView2Icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:maxWidth="100dp"
android:maxHeight="100dp"
android:scaleType="fitCenter"
android:contentDescription="@string/descForIcon"
/>
<Button
android:id="@+id/btnChangeImageForIcon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/change_icon" />
</LinearLayout>
And then here is my java coding:

} catch (Exception e) {

}
}
UPDATED CODE THAT I AM WORKING WITH:
package com.example.awesomefilebuilderwidget;
IMPORTS

}
}
}
Answer1:You are using the same resultCode SELECT_PICTUREso the result can go to either one.
You should use different result codes for the two actions you are launching.
EDIT
Code to help what was said in comments:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE)
{
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
Bitmap b1 = getAndDecodeImage(selectedImagePath);
if(b1 != null){
image.setImageBitmap(b1);
}
} else if (requestCode == SELECT_PICTURE_2)
{
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
Bitmap b2 = getAndDecodeImage(selectedImagePath);
if(b2 != null){
image2.setImageBitmap(b2);
}
}
}
}
private Bitmap getAndDecodeImage(String selectedImagePath){
try {
FileInputStream fileis=new FileInputStream(selectedImagePath);
BufferedInputStream bufferedstream=new BufferedInputStream(fileis);
byte[] bMapArray= new byte[bufferedstream.available()];
bufferedstream.read(bMapArray);
Bitmap bMap = BitmapFactory.decodeByteArray(bMapArray, 0, bMapArray.length);
if (fileis != null)
{
fileis.close();
}
if (bufferedstream != null)
{
bufferedstream.close();
}
return bMap;
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
