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
答案 0 :(得分：0)
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.
}
}
}
}
