Android 如何从相机中捕获图像，在片段中，
我是Android新手，我做了很多训练，但图像无法从相机加载。以下是我从照相机或多媒体资料中捕获图像的代码：Android 如何从相机中捕获图像，在片段中，,android,android-camera,android-imageview,android-image,Android,Android Camera,Android Imageview,Android Image,我是Android新手，我做了很多训练，但图像无法从相机加载。以下是我从照相机或多媒体资料中捕获图像的代码： public void showDiloag(){ Dialog dialog = new Dialog(getActivity()); AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); builder.setTitle("Choose Image Source");
public void showDiloag(){
Dialog dialog = new Dialog(getActivity());
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Choose Image Source");
builder.setItems(new CharSequence[] { "Gallery", "Camera" },
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog,
int which) {
switch (which) {
case 0:
Intent intent = new Intent(
Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
Intent chooser = Intent
.createChooser(
intent,
"Choose a Picture");
getAcitivity.startActivityForResult(
chooser,
ACTION_REQUEST_GALLERY);
break;
case 1:
Intent cameraIntent = new Intent(
android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(
cameraIntent,
ACTION_REQUEST_CAMERA);
break;
default:
break;
}
}
});
builder.show();
dialog.dismiss();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
System.out.println("OnActivityResult");
if (resultCode == getActivity().RESULT_OK) {
if (requestCode == Utils.ACTION_REQUEST_GALLERY) {
// System.out.println("select file from gallery ");
Uri selectedImageUri = data.getData();
String tempPath = JuiceAppUtility.getPath(
selectedImageUri, getActivity());
Bitmap bm = JuiceAppUtility
.decodeFileFromPath(tempPath);
imgJuice.setImageBitmap(bm);
} else if (requestCode == Utils.ACTION_REQUEST_CAMERA) {
Bitmap photo = (Bitmap) data.getExtras()
.get("data");
imgJuice.setImageBitmap(photo);
}
}
}
此外，图像是从相机捕获并从gallery中选择的，但不会加载到
ImageView getAcitivity.startActivityForResult(
chooser,
ACTION_REQUEST_GALLERY);
startActivityForResult(
chooser,
ACTION_REQUEST_GALLERY);
只需删除getActivity，我发现了你的问题 只需删除下面的行和
getAcitivity.startActivityForResult(
chooser,
ACTION_REQUEST_GALLERY);
startActivityForResult(
chooser,
ACTION_REQUEST_GALLERY);
