Android：添加微调器和editText动态引发异常

标签： java android android-spinner

我试图添加dinamically spinner和两个editText，但我有一个例外。我怀疑这行代码：  ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.id.simple_spinner_item,items);

因为当我试图显示一个空的微调器和两个editTexts时，它工作得很好，但是当向微调器添加值时，它会崩溃。我认为问题来自：

R.id.simple_spinner_item，我在xml文件中添加了简单的simple_spinner_item。

这是我的java代码：

LinearLayout linearLayout = (LinearLayout) findViewById(R.id.SSIDZone);
             String[] items = new String[]{  "3","4","5","6","7","8","9","10","11","12","13"};  

                for (int i =0;i<number;i++)
                { LinearLayout l = new LinearLayout(this);
                l.setOrientation(LinearLayout.HORIZONTAL);

                Spinner spin = new Spinner(this);
                ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.id.simple_spinner_item,items);//suspected line
                LayoutParams lp3 = new LayoutParams();
                l.addView(spin,lp3);
                spin.setAdapter(adapter);


                EditText text1 = new EditText(this);
                LayoutParams lp1 = new LayoutParams();
                l.addView(text1,lp1);

                EditText text2 = new EditText(this);
                LayoutParams lp2 = new LayoutParams();
                l.addView(text2,lp2);


                linearLayout.addView(l);
                }

这是我的xml布局：

<LinearLayout
            android:id="@+id/SSIDZone"
            android:layout_width="312dp"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentRight="true"
            android:layout_below="@+id/linearLayout1"
            android:layout_marginTop="88dp"
            android:layout_weight="0.46"
            android:background="#30ad9e"
            android:orientation="vertical" >

            <LinearLayout
                android:id="@+id/simple_spinner_item"
                android:layout_width="100dp"
                android:layout_height="wrap_content"
                android:orientation="vertical" >

        </LinearLayout>
        </LinearLayout>

最后这是我的LogCat：

Oups愚蠢的问题!!我没有得到足够的重视。这是一个有效的代码，以防有人需要它。

LinearLayout linearLayout = (LinearLayout) findViewById(R.id.SSIDZone);
         String[] items = new String[]{  "3","4","5","6","7","8","9","10","11","12","13"};  

            for (int i =0;i<number;i++)
            { LinearLayout l = new LinearLayout(this);
            l.setOrientation(LinearLayout.HORIZONTAL);

            Spinner spin = new Spinner(this);
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_selectable_list_item,items);//suspected line
            LayoutParams lp3 = new LayoutParams();
            l.addView(spin,lp3);
            spin.setAdapter(adapter);


            EditText text1 = new EditText(this);
            LayoutParams lp1 = new LayoutParams();
            l.addView(text1,lp1);

            EditText text2 = new EditText(this);
            LayoutParams lp2 = new LayoutParams();
            l.addView(text2,lp2);


            linearLayout.addView(l);
            }

这是xml文件：

<LinearLayout
            android:id="@+id/SSIDZone"
            android:layout_width="312dp"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_alignParentRight="true"
            android:layout_below="@+id/linearLayout1"
            android:layout_marginTop="88dp"
            android:layout_weight="0.46"
            android:background="#30ad9e"
            android:orientation="vertical" >


        </LinearLayout>
