Implement Post Display In Profile View

Enhancing User Experience with Interactive Posts

In this article, we will explore how to implement a feature that allows users to view and interact with posts displayed in their profile view. This feature will enable users to select a post from their profile and view it in a dialog, complete with all the same functionality as the original post, including likes, comments, and date.

Setting Up the Profile Adapter

To begin, we need to set up our Profile Adapter class to handle the selection of posts. We will do this by implementing the OnItemSelectedListener interface.

Step 1: Implementing the OnItemSelectedListener Interface

public class ProfileAdapter extends RecyclerView.Adapter<ProfileAdapter.ViewHolder> implements OnItemSelectedListener {
    // ...
}

Step 2: Setting Up the OnItemSelectedListener

public class ProfileAdapter extends RecyclerView.Adapter<ProfileAdapter.ViewHolder> implements OnItemSelectedListener {
    // ...

    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        // Get the selected post
        Post selectedPost = (Post) parent.getItemAtPosition(position);

        // Display the selected post in a dialog
        displayPostInDialog(selectedPost);
    }

    @Override
    public void onNothingSelected(AdapterView<?> parent) {
        // Do nothing
    }
}

Displaying the Selected Post in a Dialog

Now that we have set up our Profile Adapter class to handle the selection of posts, we need to create a dialog that will display the selected post. This dialog should look the same as how posts are displayed in the user's feed and have all the same functionality.

Step 1: Creating the Dialog Layout

<!-- dialog_post.xml -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ImageView
        android:id="@+id/post_image"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/post_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="16sp"
        android:textStyle="bold" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <TextView
            android:id="@+id/post_likes"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:textSize="14sp" />

        <TextView
            android:id="@+id/post_comments"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:textSize="14sp" />

        <TextView
            android:id="@+id/post_date"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:textSize="sp" />

    </LinearLayout>

    <Button
        android:id="@+id/button_like"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Like" />

    <Button
        android:id="@+id/button_comment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Comment" />

</LinearLayout>

Step 2: Displaying the Selected Post in the Dialog

public class ProfileAdapter extends RecyclerView.Adapter<ProfileAdapter.ViewHolder> implements OnItemSelectedListener {
    // ...

    private void displayPostInDialog(Post selectedPost) {
        // Create a new dialog
        Dialog dialog = new Dialog(context);
        dialog.setContentView(R.layout.dialog_post);

        // Get the dialog views
        ImageView postImage = (ImageView) dialog.findViewById(R.id.post_image);
        TextView postText = (TextView) dialog.findViewById(R.id.post_text);
        TextView postLikes = (TextView) dialog.findViewById(R.id.post_likes);
        TextView postComments = (TextView) dialog.findViewById(R.id.post_comments);
        TextView postDate = (TextView) dialog.findViewById(R.id.post_date);
        Button buttonLike = (Button) dialog.findViewById(R.id.button_like);
        Button buttonComment = (Button) dialog.findViewById(R.id.button_comment);

        // Set the post image
        postImage.setImageResource(selectedPost.getImage());

        // Set the post text
        postText.setText(selectedPost.getText());

        // Set the post likes
        postLikes.setText("Likes: " + selectedPost.getLikes());

        // Set the post comments
        postComments.setText("Comments: " + selectedPost.getComments());

        // Set the post date
        postDate.setText("Date: " + selectedPost.getDate());

        // Set the button click listeners
        buttonLike.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Like the post
                selectedPost.like();
            }
        });

        buttonComment.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Comment on the post
                selectedPost.comment();
            }
        });

        // Show the dialog
        dialog.show();
    }
}
