@Override
    public void onCreate(Bundle savedInstanceState) 
    
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button button = (Button)findViewById(id);
 button.setonClickListener(new View.onClickListener()
            
         public void onClick(View view)
            
                Intent intent = new Intent();
                intent.putExtra("aspectX", 730);
                intent.putExtra("aspectY", 1115);
                intent.putExtra("outputX", 730);
                intent.putExtra("outputY", 1115);
                intent.setAction("android.media.action.IMAGE_CAPTURE");
           startActivityForResult(intent, PICK_FROM_CAMERA);
                
        @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) 
    
        super.onActivityResult(requestCode, resultCode, data);

        switch(requestCode)
        
            case PICK_FROM_CAMERA : if (resultCode == RESULT_OK)
             
                ContentValues values = new ContentValues();
                values.put(Images.Media.TITLE, "title");
                values.put(Images.Media.BUCKET_ID, "test");
                values.put(Images.Media.DESCRIPTION, "test Image taken");
                values.put(Images.Media.MIME_TYPE, "image/jpeg");
                Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
                Bitmap photo = (Bitmap) data.getExtras().get("data");
                ((ImageView)findViewById(R.id.selectedimage)).setImageBitmap(photo);
                OutputStream outstream;
                try 
                        outstream = getContentResolver().openOutputStream(uri);
                        photo.compress(Bitmap.CompressFormat.JPEG,100, outstream);
                        outstream.close();
                 catch (FileNotFoundException e) 
                catch (IOException e)
            
            break;

请检查这个答案：

public class ImageUploading extends Activity 
   
    Uri imageUri = null;
    ImageButton btnSubmit   ;
    public void onCreate(Bundle onsavedInstantState)
    
        super.onCreate(onsavedInstantState);
        setContentView(R.layout.edit_profile);
        btnSubmit               = (ImageButton) findViewById(R.id.btnSubmit);       
        btnSubmit.setClickable(true);       
        btnSubmit.setOnClickListener(new View.OnClickListener()
                   
            @Override
            public void onClick(View v)            
                Intent cameraIntent = new Intent("android.media.action.IMAGE_CAPTURE");
                File imgFile = new File(Environment.getExternalStorageDirectory(),"my_photo.png");
                imageUri = Uri.fromFile(imgFile);
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);               
                startActivityForResult(cameraIntent,0);             
            
        );
       
    @Override
    public void onActivityResult(int RequestCode, int ResultCode, Intent imageIntent)
    
        super.onActivityResult(RequestCode, ResultCode, imageIntent);
        try
        
            if(RequestCode == 0)
            
                if(ResultCode == Activity.RESULT_OK)
                
                    getContentResolver().notifyChange(imageUri, null);
                    ContentResolver objContentResolver = getContentResolver();
                    Bitmap imgBitmap = android.provider.MediaStore.Images.Media.getBitmap(objContentResolver, imageUri);
                    Drawable imgDrawable = new BitmapDrawable(imgBitmap);
                    btnSubmit.setBackgroundDrawable(imgDrawable);
                
                       
        
        catch(Exception e)
        
    

它将在按钮单击时捕获图像，并将此图像设置为该按钮本身的背景图像。
