如何在使用setView(int layoutResId)时从AlertDialog中获取膨胀视图?

如果我没记错, create show 首先,然后,找到你要找的风景。

val dialog = AlertDialog.Builder(context)
            .setView(R.layout.layout)
            .create()

dialog.show() // Cause internal layout to inflate views
dialog.findViewById(...)

而不是使用 alert dialog 使用 simple Dialog 很简单很简单

final Dialog dialog = new Dialog(context);
        dialog.setContentView((R.layout.layout);
        dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

        TextView tvTitle = (TextView) dialog.findViewById(R.id.tvTitle);
        tvTitle.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

            }
        });

AlertDialog.Builder dialog = new AlertDialog.Builder(context);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE );
View view = inflater.inflate( R.layout.layout, null );
dialog.setView(view);
dialog.create().show();

你夸大的观点现在 view

EditText editText = view.findViewById(R.id.myEdittext);

试试这个;

View dialogView; //define this as a gobal field

dialogView = LayoutInflater.from(context).inflate(R.layout.your_view, null);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Title");
builder.setView(dialogView);

View yourView = dialogView.findViewById(R.id.a_view_in_the_layout);
TextView yourTextView = dialogView.findViewById(R.id.a_textView_in_the_layout);
Button yourButton = dialogView.findViewById(R.id.a_button_in_the_layout);
