没有软键盘的对话框内的EditText [英] No soft keyboard for the EditText inside the Dialog Box

问题描述

我想创建一个对话框，用户可以插入一个号码;所以我overrided的onCreateDialog方法是这样的：

I'd like to create a Dialog Box where the user can insert a number; so I overrided the onCreateDialog method this way:

protected Dialog onCreateDialog(int id) {
            EditText editNum=new EditText(this);
            editNum.setMaxLines(1);
            editNum.setRawInputType(InputType.TYPE_CLASS_NUMBER);
            String strVal=listViewNum.getItemAtPosition(selectedItem).toString();
            strVal=strVal.substring(strVal.indexOf("=")+1,strVal.length()-1);
            editNum.setText(Util.formatNumber(Double.parseDouble(strVal)));
            editNum.selectAll();
            editNum.setGravity(android.view.Gravity.RIGHT);
            return new AlertDialog.Builder(this)
            .setTitle(getString(R.string.DialogEditNumberTitle))
            .setView(editNum)
            .setPositiveButton("OK", new OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                            // TODO Auto-generated method stub

                    }
            })
            .setNegativeButton("Annulla", new OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                            // TODO Auto-generated method stub

                    }
            })
            .create();
    }

但尽管如此我还是允许插入非数字字符，也没有软键盘的迹象......有什么错我的code？

But despite this I'm still allowed to insert non-numeric characters and there is no sign of the soft keyboard...what's wrong with my code?

推荐答案

我不知道，你可以通过编程做什么，而是你可以如下创建自己的自定义布局，将包含一个EditText：

I'm not sure what you could do programmatically, BUT you could create your own custom layout which will contain an edittext as follows:

<EditText android:id="@+id/myEditText"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:inputType="numbers"
android:digits="0123456789"/>

然后在code为onCreateDialog：

and then in the code for the onCreateDialog:

    LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View myLayout = inflater.inflate(R.layout.myLayout, null); //I showed this as a linear layout before, but it must be a view to inflate it
        EditText myEditText = (EditText)myLayout.findViewById(R.id.myEditText);
        //create myEditText listener here, if needed




dialog.setView(myLayout);
