How to Get Fetch camera image inside imageview on button click with runtime permission.

In this tutorial we are going to create an android application with imageview with button widget and also with Request runtime camera permission inbuilt code. So when the app starts then it will ask about Runtime permission to access mobile phone camera.

So here is the complete step by step tutorial for Capture Image from Camera and Display in ImageView android Programmatically.

How to Capture Image from Camera and Display in ImageView android Programmatically.

Please add CAMERA permission inside your AndroidManifest.xml file .

<uses-permission android:name="android.permission.CAMERA" />

Code for MainActivity.java file.

package com.android_examples.captureimagecamera_android_examplescom;
import android.Manifest;
import android.content.Intent;
import android.content.pm.PackageManager;
import android.graphics.Bitmap;
import android.support.v4.app.ActivityCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

    Button button ;
    ImageView imageView ;
    Intent intent ;
    public  static final int RequestPermissionCode  = 1 ;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        button = (Button)findViewById(R.id.button);
        imageView = (ImageView)findViewById(R.id.imageView);

        EnableRuntimePermission();

        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                intent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

                startActivityForResult(intent, 7);

            }
        });
    }


    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (requestCode == 7 && resultCode == RESULT_OK) {

            Bitmap bitmap = (Bitmap) data.getExtras().get("data");

            imageView.setImageBitmap(bitmap);
        }
    }

    public void EnableRuntimePermission(){

        if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,
                Manifest.permission.CAMERA))
        {

            Toast.makeText(MainActivity.this,"CAMERA permission allows us to Access CAMERA app", Toast.LENGTH_LONG).show();

        } else {

            ActivityCompat.requestPermissions(MainActivity.this,new String[]{
                    Manifest.permission.CAMERA}, RequestPermissionCode);

        }
    }

    @Override
    public void onRequestPermissionsResult(int RC, String per[], int[] PResult) {

        switch (RC) {

            case RequestPermissionCode:

                if (PResult.length > 0 && PResult[0] == PackageManager.PERMISSION_GRANTED) {

                    Toast.makeText(MainActivity.this,"Permission Granted, Now your application can access CAMERA.", Toast.LENGTH_LONG).show();

                } else {

                    Toast.makeText(MainActivity.this,"Permission Canceled, Now your application cannot access CAMERA.", Toast.LENGTH_LONG).show();

                }
                break;
        }
    }

}
