I am creating an Contact app with SQLITE. If anyone want to store a person contact, he will fill up the name, number and person image. If he does not select an image, the app will set default image. But how i can show these two types of picture i mean selected image and default image because my app show only default image.

Database

`public class DatabaseHelper extends SQLiteOpenHelper {

final static String DB_NAME = "contactList.db", TABLE_NAME = "contactDetails";
final static int VERSION = 1;

public DatabaseHelper(Context context) {
    super(context, DB_NAME, null, VERSION);
}

@Override
public void onCreate(SQLiteDatabase sqLiteDatabase) {
    sqLiteDatabase.execSQL("create table contactDetails "  
            "(id integer primary key autoincrement, "  
            "defaultIMG int, "  
            "uploadIMG text, "  
            "name text, "  
            "number text)"
    );
}

@Override
public void onUpgrade(SQLiteDatabase sqLiteDatabase, int i, int i1) {

}




public ArrayList<ImageNameNumberModel> getContacts() {
    SQLiteDatabase db = this.getReadableDatabase();
    ArrayList<ImageNameNumberModel> contacts = new ArrayList<>();

    Cursor cursor = db.rawQuery("SELECT * FROM contactDetails", null);

    if (cursor.moveToFirst()) {
        while (cursor.moveToNext()) {
            int id = cursor.getInt(0);
            int defIMG = cursor.getInt(1);
            String upIMG = cursor.getString(2);
            String name = cursor.getString(3);
            String number = cursor.getString(4);

            ImageNameNumberModel model = new ImageNameNumberModel(id, defIMG,
                    Uri.parse(upIMG), name, number);
            contacts.add(model);
        }
    }


    return contacts;
}


public void insert(int defaultIMG, Uri uploadIMG, String name, String number) {

    SQLiteDatabase db = this.getWritableDatabase();
    ContentValues contentValues = new ContentValues();
    contentValues.put("defaultIMG", defaultIMG);
    contentValues.put("uploadIMG", String.valueOf(uploadIMG));
    contentValues.put("name", name);
    contentValues.put("number", number);

    db.insert(TABLE_NAME, null, contentValues);

CodePudding user response：

All you need to do is check if the ImageNameNumberModel contains uploadImage path. If it has then load the selected image from disk else load the default image from resources.

For Image loading in android you can use any of the common image handling libraries like Glide, Picasso etc

CodePudding user response：

check like this

 If(!ImageNameNumberModel[position].uploadImage.isNullOrEmpty() $$ 
         !ImageNameNumberModel[position].uploadImage=="null"){
     
Glide.with(context).load(ImageNameNumberModel[position].uploadImage).into(imageView)

}else{
   imageView.setBackgroundResource(R.drawable.image)
}

Note:- Here User as per your model class and image view please use glide library also

Basically above code do check if your model class have an image URL or not if yes then set that URL image to your image view else default one
