美好的一天，
我创建了一个方法showDialog，它将显示一个Alert Dialog并列出我可以选择的多个数据。我的问题是当我单击OK时，我想调用的下一个方法（myMethod（））没有被调用。有人可以帮我弄这个吗？这是我的代码：
private void showDialog(List<String> list) {
final CharSequence[] dialogList= list.toArray(new CharSequence[list.size()]);
final AlertDialog.Builder builderDialog = new AlertDialog.Builder(SharingActivity.this);
builderDialog.setTitle("Select Item");
int count = dialogList.length;
boolean[] is_checked = new boolean[count];
String result = "";
builderDialog.setMultiChoiceItems(dialogList, is_checked,
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog,
int whichButton, boolean isChecked) {
}
});
builderDialog.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
ListView list = ((AlertDialog) dialog).getListView();
// make selected item in the comma seprated string
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < list.getCount(); i++) {
boolean checked = list.isItemChecked(i);
if (checked) {
if (stringBuilder.length() > 0) stringBuilder.append(",");
stringBuilder.append(list.getItemAtPosition(i));
}
}
myMethod(stringBuilder.toString()); //this is the method
}
});
builderDialog.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
((TextView) findViewById(R.id.text)).setText("Click here to open Dialog");
}
});
AlertDialog alert = builderDialog.create();
alert.show();
}
这是myMethod：
private void myMethod(String stringFriend){
Bundle extras = getIntent().getExtras();
byte[] byteArray = extras.getByteArray("image");
Bitmap image = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
//Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
SharePhoto photo = new SharePhoto.Builder()
.setBitmap(image)
.setCaption("")
.build();
List<String> peopleIds = new ArrayList<String>();
peopleIds.add(stringFriend);
SharePhotoContent content = new SharePhotoContent.Builder()
.addPhoto(photo)
.setPeopleIds(peopleIds)
.build();
ShareApi.share(content, null);
}
