Question

我想创建一个这样的对话框：

required dialog click here

当用户点击链接中给出的个人资料图片时，我需要创建对话框。目前我这样做

    final CharSequence[] items = { "Gallery", "Camera", "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
    builder.setTitle("Add Photo!");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int item) {

            if (items[item].equals("Gallery")) {

                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp1.jpg");
                mImageCaptureUri = Uri.fromFile(f);
                intent.putExtra(MediaStore.EXTRA_OUTPUT, mImageCaptureUri);
                startActivityForResult(intent, CAMERA_CODE);

            } else if (items[item].equals("Camera")) {

                Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                startActivityForResult(i, GALLERY_CODE);

            } else if (items[item].equals("Cancel")) {
                dialog.dismiss();
            }
        }
    });
    builder.show();

我不知道该如何设计，请帮助我。

有两种方法可以实现这一目标。

使用自定义提醒对话框。
通过查询意图活动使用Intent。

默认情况下，Android不会显示单次打开相机和图库的选项。但做一些技巧将有助于实现这一目标。

请参阅以下代码，该代码用于在单个默认对话框中显示相机和图库浏览选项。

// Picks Camera first.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(
        android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(
        captureIntent, 0);
for (ResolveInfo res : listCam) {
  final String packageName = res.activityInfo.packageName;
  final Intent intent = new Intent(captureIntent);
  intent.setComponent(new ComponentName(res.activityInfo.packageName,
          res.activityInfo.name));
  intent.setPackage(packageName);
  intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
  cameraIntents.add(intent);
}

final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_PICK);

// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent,
        "Select Image from");

// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
        cameraIntents.toArray(new Parcelable[]{}));

startActivityForResult(chooserIntent, TAKE_PHOTO_CODE);

这里已经回答了相同类型的问题。！ - ＆GT; queryIntentActivityOptions not working

希望这会对你有所帮助，

对话就像使用完整动作一样
