Question

我有一个dialogfragment，它的视图包含一个简单的搜索栏和正负按钮。当我解除对话碎片onclick时，会创建一个新的对话碎片并显示出来。在第二次单击按钮后，对话框被取消，但我的愿望是在第一次点击后解雇。另外我应该注意，我的活动包含两个片段，我从第一个片段调用dialog.show（）。

MyListFragment.java

FragmentManager manager = getFragmentManager();
fndSrchFragment dialog = new fndSrchFragment();
dialog.setTargetFragment(MyListFragment.this, REQUEST_COLOR);
dialog.show(manager, SRCH_FND);

fndSrchFragment.java

public class fndSrchFragment  extends DialogFragment {
.
.
//variable definition
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
View view = LayoutInflater.from(getActivity()).inflate(R.layout.color_picker, null);
rSb=(SeekBar) view.findViewById(R.id.r_seek_bar);
.
.
//code for interacting with seekbar
.
.
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setView(view);
    builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            int ccolor = android.graphics.Color.rgb(rComponent, gComponent, bComponent);
            sendResult(Activity.RESULT_OK, ccolor);
            // two click is needed for dismiss which I don't know why?
            dismiss();
        }
    });
    builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            // two click is needed for dismiss which I don't know why?
            dismiss();
        }
    });
    return builder.create();
}

先谢谢你。

在onMenuItemActionExpand()内设置日志命令。我打赌你在解除对话后立刻就会看到这个方法。最有可能的是，一旦焦点从对话框返回到活动，系统就会调用此方法。您应该在dialog.show()之内调用onOptionsItemSelected(MenuItem item)，而不是$student_mark = array(); foreach($studen_id as $row){ $mark_obtained = ...... $student_mark[] = $mark_obtained; ....。

Dismiss DialogFragment onClick无法正常工作
