Undefined for the type new View.OnClickListener(){}

When I use the project as public class HomeActivity extends Activity implements OnClickListener and inside that I use getContentResolver it show me the error

The method getContentResolver() is undefined for the type new View.OnClickListener(){}

But when I use public class HomeActivity extends ActionBarActivity it works for me , but how I can handle it in public class HomeActivity extends Activity implements OnClickListener

Code :

public class HomeActivity extends Activity implements OnClickListener  {
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        btnEdit = (Button) findViewById(R.id.btn_edit);
        btnEdit.setOnClickListener(this);

        btnGallery = (Button) findViewById(R.id.btn_gallery);
        btnGallery.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        Intent intent;
        switch (view.getId()) {
        case R.id.btn_edit:
            intent = new Intent();
            intent.setType("image/*");

            intent.setAction(Intent.ACTION_GET_CONTENT);
            startActivityForResult(intent, REQUEST_IMAGE);
    //      startActivityForResult(
    //              Intent.createChooser(intent, "Select Photo"),
    //              MyConstants.TAKE_PHOTO);
            break;  
        }
    }

    @Override
    public void onBackPressed() {
        super.onBackPressed();
    }
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (resultCode != Activity.RESULT_OK) {return;}

            if (requestCode == REQUEST_IMAGE) {
                final Uri uri = data.getData();
                    Button button= (Button) findViewById(R.id.btn_camera);
                    button.setOnClickListener(new OnClickListener() {
                          @Override
                          public void onClick(View v)  {  
                              try
                                {
                                InputStream is = this.getContentResolver().openInputStream(uri);
                                final Bitmap bmInImg = BitmapFactory.decodeStream(is);

                                }
                                catch (IOException e) {
                                    e.printStackTrace(); 
                                }

                          }
                        });

                }
            }

Reasoning:

Because getContentResolver() is the method of the Context Class, not the method of View.OnClickListener Interface.

And when you are writing this line

InputStream is = this.getContentResolver().openInputStream(uri);

You are using this to call the method from View.OnClickListener Interface, Which is not present in Interface, thats why Android is giving you error.

See Context class Here And View.OnClickListener Here

Answer:

Declare a gloabal Context Variable.

       // Global Var
       Context context;

       // In onCreate
       context = this;

Change this line to 

       InputStream is = this.getContentResolver().openInputStream(uri);

THIS:

       InputStream is = context.getContentResolver().openInputStream(uri);

In this line :

InputStream is = this.getContentResolver().openInputStream(uri);

"this" refers to the ClickListener you're creating. You need to use the "this" of the enclosing class like that :

InputStream is = HomeActivity.this.getContentResolver().openInputStream(uri);
