调用系统相机相册

方法一：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	super.onActivityResult(requestCode, resultCode, data);
//		Uri uri = data.getData();
//		image.setImageURI(uri);
	
	//得到拍摄的照片
	Bitmap bitMap=data.getParcelableExtra("data");
	image.setImageBitmap(bitMap);

}

@Override
public void onClick(View v) {
	switch (v.getId()) {
	case R.id.button1:
		Intent intent= new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
		intent.addCategory("android.intent.category.DEFAULT");
		startActivityForResult(intent,1001);

		break;

	case R.id.button2:
		Intent intent1 = new Intent(Intent.ACTION_PICK);
		intent1.setType("image/*");
		startActivityForResult(intent1, 0);
		break;

	}

}

方法二：
private void takephoto() {
    final String[] item = {"相册","拍照"};
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle("请选择获取相片方式：");
    builder.setItems(item, new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int which) {
            switch (which) {
                case 0:
                    goXiangChe();
                    xc = 0;
                    break;
                case 1:
                    xc=1;
                    goXiangJi();
                    break;
            }
        }
    });
    builder.create().show();
}
/*调用相机*/
private void goXiangJi() {
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT,false);
    startActivityForResult(intent, 1);
}
 private int xc;
/*调用相册*/
protected void goXiangChe() {
    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_GET_CONTENT);
    intent.setType("image/*");
    startActivityForResult(intent, 111);
}
private Bitmap bitmap;
//不管是拍照还是在相册里选择相片，都会调用这个方法
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK) {
        Uri uri = data.getData();
        ContentResolver cr = getActivity().getContentResolver();
        try {
            if (xc==0){
                bitmap = BitmapFactory.decodeStream(cr.openInputStream(uri));
            }else {
                bitmap = data.getParcelableExtra("data");
            }
            if (uri ==null){
                uri = Uri.parse(MediaStore.Images.Media.insertImage(getActivity().getContentResolver(), bitmap, null,null));
            }
            mytouxiang.setImageBitmap(bitmap);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
