Question

我正在尝试从自定义alertdilog的按钮单击事件中显示片段，警报对话框在片段的适配器中，我想显示来自alertdialog按钮单击的片段，但我无法这样做。

alertdialog代码：

    holder.commentButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {

                        AlertDialog.Builder builder=new AlertDialog.Builder(context);
                        final AlertDialog alertDialog=builder.create();

                        View viewTmp_comment=LayoutInflater.from(context).inflate(R.layout.comment_show_layout,null,false);
                        RecyclerView recyclerView_commentShow=(RecyclerView)viewTmp_comment.findViewById(R.id.recyclerViewId_commentShow);
                        TextView textViewId_commentShow_layout=(TextView)viewTmp_comment.findViewById(R.id.textViewId_commentShow_layout);
                        ImageButton commentSendButtonId_Post=(ImageButton)viewTmp_comment.findViewById(R.id.commentSendButtonId_Post);
                        ImageButton imageUpload_CommentButton=(ImageButton)viewTmp_comment.findViewById(R.id.imageUploadButtonId_comment);
                        ImageButton smileyUpload_CommentButton=(ImageButton)viewTmp_comment.findViewById(R.id.smileyButtonId_comment);
                        editTextId_CommentPost=(EditText) viewTmp_comment.findViewById(R.id.editTextId_CommentPost);
    //                RelativeLayout smileyLoadLayoutId_CommentAdapter=(RelativeLayout)

                        final CommentShowAdapter commentShowAdapter=new CommentShowAdapter(context,newsFeedClassArrayList.get(position).getCommentShowClassArrayList(),"NewsFeed");
                        LinearLayoutManager linearLayoutManager=new LinearLayoutManager(context);
                        recyclerView_commentShow.setLayoutManager(linearLayoutManager);
                        if(newsFeedClassArrayList.get(position).getCommentShowClassArrayList()!=null) {
                            recyclerView_commentShow.setAdapter(commentShowAdapter);

                            DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(context, linearLayoutManager.getOrientation());
                            recyclerView_commentShow.addItemDecoration(dividerItemDecoration);
                            commentShowAdapter.notifyDataSetChanged();
                            recyclerView_commentShow.onChildDetachedFromWindow(null);
                        }else {
                            builder.setMessage("No comments yet");
                        }

                    //comment show alert dismiss
                    textViewId_commentShow_layout.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            try {
                                if(alertDialog.isShowing()){
                                    alertDialog.dismiss();
                                }
                            }catch (Exception e){}
                        }
                    });


**//here i am trying to lauch fragment**
                    smileyUpload_CommentButton.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            ServiceClass.setSmileyKey("comment");

                            smileyFragment=new SmileyShowFragment();

                            FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction();
                            Fragment fragment = fragmentManager.findFragmentById(R.id.smileyLoadLayoutId_CommentAdapter);

                            if (!(fragment instanceof SmileyShowFragment)) {

                                fragmentTransaction.replace(R.id.smileyLoadLayoutId_CommentAdapter, smileyFragment, "Smiley").commit();
                            } else {

                                fragmentTransaction.remove(smileyFragment).commit();

                            }
                        }
                    });

                        WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
                        Window window = alertDialog.getWindow(); lp.copyFrom(window.getAttributes());
                        lp.width = context.getResources().getDisplayMetrics().widthPixels;
                        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
                        lp.gravity=Gravity.BOTTOM; window.setAttributes(lp);

                        alertDialog.setView(viewTmp_comment);
                        alertDialog.show();
                }
            });

如何解决这个问题？是否有可能在alertdialog.i中显示片段已在谷歌搜索但没有类似的解决方案

您应该创建一个单独的自定义对话框。为此，您可以扩展DialogFragment并在onCreateDialog（）上设置您的视图和正确的分配。为自定义对话框片段类创建一个布局，其中包含一个片段。您可以在自定义对话框上创建界面，以侦听按钮单击或其他操作。然后，单击您的按钮使用片段管理器在对话框片段中显示片段。如下所示：

//给它一个带有FrameLayout的片段来保存片段需要持有多个或只需在布局中添加片段如果你不需要持有人。

public class MyCustomizedDialog extends DialogFragment{

private TextView dialogTitle;
private TextView dialogText;
private FrameLayout myFragmentContainer;
private Button myButton;
private CustomDialogListener customDialogListener;

public interface CustomDialogListener{
  //set listeners here, i.e. for buttons clicked by user
  public void onBtnClick();
}

public setDialogFragmentListener(CustomDialogListener customDialogListener){
    this.customDialogListener = customDialogListener;
}
@override
public Dialog onCreateDialog(Bundle savedInstanceState) { 
  //initialize dialog
  setUpMyCustomDialog(dialog);
  return dialog;
}

public void setUpMyCustomDialog(Dialog dialog){
    dialogTitle = (TextView)dialog.findViewById(R.id.dialog_title_tv);
    dialogText = (TextView)dialog.findViewById(R.id.dialog_text_tv);
    myFragmentContainer=(FrameLayout)dialog.findViewById(R.id.child_fragment_container);
    myButton = (Button)dialog.findViewById(R.id.myButton);

    myButton.setOnClickListener(new OnClickListener(){
        public void onClick(View view) {
        //initialize your fragment here.
        }
    }

}

}
