How can I integrate the RecyclerView with images in android?

How can I integrate the RecyclerView with images in android? - java

I am trying to create the image gallery . I am using the recyclerview for the same as there can be large number of images. This is what I am trying to do :
When the user opens up the app android will ask for its permission for images (working)
After selecting either option add it to the image view present in the recyclerview (not working).
If image is saved how to re-render it back to the recyclerview (not working)
Here is what I am trying to do :
This is my Activity file named GalleryActivity.java :

startActivityForResult(pickPhoto, 1);//one can be replaced with any action code
} else if (options[item].equals("Cancel")) {

How to zoom out a bitmap image?

I'm capturing an image using a biometric reader.
Connecting the reader to the tablet and capturing the image works fine, but the image looks like this:
The image is cropped. It looks like it's magnified when the biometric capture takes place.
this is my code:
package mobfeel.com.br.exfingerprintreaderuareu4500;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Matrix;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Base64;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
import java.io.ByteArrayOutputStream;
import asia.kanopi.fingerscan.Status;
public class MainActivity extends AppCompatActivity {
private ImageView ivFingerprint;
private Button btScan;
private static final int SCAN_FINGERPRINT = 1234;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
btScan.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, ScanActivity.class);
startActivityForResult(intent, SCAN_FINGERPRINT);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case SCAN_FINGERPRINT:
if (resultCode == RESULT_OK) {
int status = data.getIntExtra("status", Status.ERROR);
if (status == Status.SUCCESS) {
toast("Fingerprint OK!");
byte[] img = data.getByteArrayExtra("img");
Bitmap bm = BitmapFactory.decodeByteArray(img, 0, img.length);
ivFingerprint.setImageBitmap(bm);
return;
}
toast(data.getStringExtra("errorMessage"));
}
break;
}
}
private void toast(String msg){
Toast.makeText(getBaseContext(), msg, Toast.LENGTH_SHORT).show();
}
private void init(){
ivFingerprint = findViewById(R.id.ma_iv_fingerprint);
btScan = findViewById(R.id.ma_bt_scan);

Another issue I know I'll encounter is the null reference exception.
How do I reference the buttons from the cardview layout when the content view is set to be shown from the other one.

Android: How to create a filtering function with Checkbox

I am trying to create a filtering function with checkbox for my application. I have populated a list of installed application and i want to filter out only a few it. My idea is to get those checkbox that are checked and store it into an array. After which, display it back into a listview.
Example:
For this example, i would like to only list out Maps and Camera upon clicking on the submit button.
Does anyone know what should i do to achieve this? I'm clueless at the moment due to my knowledge of android studio.
