Android 一起从图库或相机显示选项中选择图片

Question

在我的 onClick 方法中，我调用了两个新的意图，一个是用相机拍照，另一个是从图库中选择图像。但是，每当我在开始 activity 之前允许这两个意图时，允许对话的弹出窗口总是相互重叠。

Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);

Intent pickPhoto = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto , 1);

我首先会看到允许从图库中选择图片的选项，向下滑动后，我会看到允许使用相机的选项。如何在一个弹出窗口中显示它？

您可以执行以下操作....

private void showPickImageDialog() {
    AlertDialog.Builder builderSingle = new AlertDialog.Builder(MainActivity.this);
    builderSingle.setTitle("Select One Option");

    final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
            MainActivity.this,
            android.R.layout.select_dialog_singlechoice);
    arrayAdapter.add("Gallery");
    arrayAdapter.add("Camera");

    builderSingle.setNegativeButton(
            "cancel",
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });

    builderSingle.setAdapter(
            arrayAdapter,
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    switch (which) {
                        case 0:
                            Intent pickPhoto = new Intent(Intent.ACTION_PICK,
                                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                            startActivityForResult(pickPhoto, 1);
                            break;

                        case 1:
                            Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                            startActivityForResult(takePicture, 0);
                            break;
                    }

                }
            });
    builderSingle.show();
}

希望这对你有用！！
