In this Project we are making app where user can use the camera from our app instead of using default camera app, also we are displaying that clicked image on our Image View in the app
Code:-
MainActivity.java:-
package com.example.cameraapp;
import androidx.annotation.Nullable;
import
androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
public class MainActivity extends
AppCompatActivity {
public static final int CAMERA_PERM_CODE = 101;
public static final int REQUEST_CODE = 102;
private static final int CAMERA_REQUEST_CODE = 102;
ImageView selectedImage;
Button camerabtn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
selectedImage = findViewById(R.id.DisplayView);
camerabtn = findViewById(R.id.camerbtn);
camerabtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
askCameraPermission();
}
});
}
private void askCameraPermission() {
if(ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED){
ActivityCompat.requestPermissions(this,new String[]
{Manifest.permission.CAMERA},CAMERA_PERM_CODE);
}
else{
openCamera();
}
}
private void openCamera() {
Toast.makeText(this, "Using Camera", Toast.LENGTH_SHORT).show();
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera,CAMERA_REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode,
@Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode == CAMERA_REQUEST_CODE){
Bitmap image = (Bitmap) data.getExtras().get("data");
selectedImage.setImageBitmap(image);
}
}
}
