启动对话框时如何显示键盘？

Question

我想在打开对话框时显示键盘。

这是我的代码：

var array: Array<String> = arrayOf("Edit", "Delete")
 val builder = AlertDialog.Builder(activityContext)
 builder.setTitle("Options:").setItems(array, DialogInterface.OnClickListener {dialog, which ->
        if(which == 0) { //edit
           val mDialogView = LayoutInflater.from(activityContext).inflate(R.layout.activity_contact_info_description_dialog, null)
           val mBuilder = AlertDialog.Builder(activityContext).setView(mDialogView).setTitle("File name")
           val mAlertDialog = mBuilder.show()
    }

这会有所帮助

AlertDialog.Builder builder1 = new AlertDialog.Builder(context);

AlertDialog dialog = builder1.create();
dialog.getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);
dialog.show();
