How to call getDrawable method

Question

I am creating an image sharing app which uses a button to share images. I'm getting an unable to resolve the required method error in the code below:

public class ShareActivity extends Activity implements View.OnClickListener {

    Button button1;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_share);

        button1 = (Button)findViewById(R.id.button1);
        button1.setOnClickListener(this);
    }
    private void button1Click()
    {
        BitmapDrawable bm = (BitmapDrawable) getDrawable(button1);
        Bitmap mysharebmp = bm.getBitmap();
        String path = Images.Media.insertImage(getContentResolver(),
                            mysharebmp, "MyImage", null);

On this line:

BitmapDrawable bm = (BitmapDrawable) getDrawable(button1);ShareActivity

I am getting The method getDrawable(Button) is undefined for the type ShareActivity. Why might I be getting this error? The full code is here.

what is that you are doing. `getDrawable(button1);` did you look at the docs for the api?. Your question is not clear. — Raghunandan, Feb 22 '14 at 10:51
i want a button which can share my images to social apps, this is what i want to do sir — , Feb 22 '14 at 10:52
what you are doing is wrong. You already have the button. To share it to social apps like facebook. You need to look at their facebooksdk. The images i guess are stored in sdcard or in gallery. You will need to get the path of those images — Raghunandan, Feb 22 '14 at 10:53
@Raghunandan sir i am new to development, i don't know how to give location to images :( — , Feb 22 '14 at 10:55

It's extremely unclear as to what you want to do here, and I suspect you're going to encounter a number of other problems with this code. But the reason that you're getting the error "getDrawable is undefined for ShareActivity" is because the Activity class does not have a getDrawable method.

Instead of calling getDrawable, you need to get the app resources and then retrieve the drawable. What you're looking for is:

BitmapDrawable bm = (BitmapDrawable) getResources().getDrawable(R.drawable.my_bitmap);

Where you have some image called "my_bitmap.png" in /res/drawable/.

Edit Feb 7 2016: This answer is no longer correct. Context#getDrawable(int) was added in API 21 (Lollipop) which was released in November 2014. Note that you probably shouldn't be using it anyway.

If you are trying to get the image displayed inside the button the consider using the function defined inside the image button object. I mean to say use button1.getDrawable()

The getDrawable() method requires id of the resource and in this case you are passing Button. Try passing R.id.button1 Here is the documentation

it still asking to create method for `getDrawable();` – Feb 22 '14 at 11:50
Post the entire error-whatever it may be... I assume you implemented the onClick(View v) method of View.OnClickListener() – Florescent Ticker Feb 22 '14 at 11:53
-1 because you can not pass the button id in the `getDrawable` – Ajay S Feb 23 '14 at 18:36
