  • 这是点击popupwindows的点击事件
case R.id.tv_pick_phone:                Toast.makeText(getActivity(), "从手机相册选择", Toast.LENGTH_SHORT).show();                popupWindow.dismiss();                Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);                startActivityForResult(intent,1);                break;

  • 实现代码(选择图片并进行setImageBitmap加载)
@Override    public void onDismiss() {        setBackgroundAlpha(1);    }    @Override    public void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        //获取图片路径        if (requestCode == CAMERA_REQUEST_CODE && resultCode == Activity.RESULT_OK && data != null) {            Uri selectedImage = data.getData();            String[] filePathColumns = {MediaStore.Images.Media.DATA};            String path = getImagePath(selectedImage,null);            Cursor c = getActivity().getContentResolver().query(selectedImage, filePathColumns, null, null, null);            c.moveToFirst();            int index=c.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);            String imagePath = c.getString(index);            showImage(imagePath);            //upload(imagePath);上传功能还没实现            c.close();        }    }    //加载图片    private void showImage(String imagePath){        Bitmap bm = BitmapFactory.decodeFile(imagePath);        ((ImageView)getActivity().findViewById(R.id.head)).setImageBitmap(bm);    }    private String getImagePath(Uri uri, String seletion) {        String path = null;        Cursor cursor = getActivity().getContentResolver().query(uri, null, seletion, null, null);        if (cursor != null) {            if (cursor.moveToFirst()) {                path = cursor.getString(cursor.getColumnIndex(MediaStore.Audio.Media.DATA));            }            cursor.close();        }        return path;    }

   }}

然后在布局里使用

<com.bo.friends.circle.CircleImageView        android:id="@+id/head"        android:layout_width="120dp"        android:layout_height="120dp"        android:layout_alignParentTop="true"        android:layout_centerHorizontal="true"        android:layout_marginTop="75dp" />
