如何从android中的所有其他微调器中删除所选项目

标签： android listview spinner

我是android的初学者。我有一个ListView，包含一个微调器，edittext和一个用于删除该行的图像按钮。微调器从列表中填充。有一个添加按钮，可以将这些项添加到列表视图中每次单击时。如果我在微调器中选择一个项目，那么我需要从该列表视图中的所有其他微调器中删除该项目，并且当我删除所选微调器行或更改微调器中的所选项目时，项目也变得可见。为简单起见，我的Spinners填充了以下数据：

{"data1", "data2", "data3", "data4", "data5"};

例如，如果我选择我的第一个ListView的Spinner值为“data3”，然后“data3”条目从所有其他ListView Spinner中消失，这将仅在我更改第一个listview微调器中的选定值时返回或删除该行，类似于每个ListView微调器。如何做到这一点？有人请帮帮我。下面是我的代码。

FundReceipt.java：

private Float amount = 0.0f;
private COAAccount selAcct;
public FundReceipt(COAAccount selAcct, Float amount) {
    this.setAmount(amount);
    this.setSelAcct(selAcct);
}
public Float getAmount() {
    return amount;
}
public void setAmount(Float amount) {
    this.amount = amount;
}
public COAAccount getSelAcct() {
    return selAcct;
}
public void setSelAcct(COAAccount selAcct) {
    this.selAcct = selAcct;
}

}

我面临同样的问题，但我可以成功从列表中删除所选项目之后我做了一个改变网络。所选项目在下拉列表中显示突出显示状态。我知道我的答案不符合您的问题，但想与您分享。

  1. 你的微调器：

             <Spinner
            android:id="@+id/sp_handi_cap"
            style="@style/SpinnerAppTheme"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"                    android:background="@drawable/selector_rectangular_gray_trans_bg"
            android:descendantFocusability="afterDescendants"
            android:gravity="start"
            android:minWidth="250dp"
            android:padding="5dp"
            android:singleLine="true" />

    2. selector_rectangular_gray_trans_bg.xml 

    <solid android:color="@android:color/transparent" />

<stroke
    android:width="1dp"
    android:color="@color/gray6" />

<corners
    android:bottomLeftRadius="0dp"
    android:bottomRightRadius="0dp"
    android:topLeftRadius="0dp"
    android:topRightRadius="0dp" /></shape>

    创建布局：

    <TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/selector_spinner_item_activited"
    android:gravity="center"
    android:padding="3dp"
    android:paddingEnd="?android:attr/listPreferredItemPaddingEnd"
    android:paddingStart="?android:attr/listPreferredItemPaddingStart"
    android:textAppearance="?android:attr/textAppearanceListItemSmall"
    android:textSize="12sp" />

    selector selector_spinner_item_activited.xml：

    <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/selector_rectangular_black_trans_bg" android:state_activated="true"/>
    <item android:drawable="@android:color/transparent"/>

</selector>

    创建适配器：

    ArrayAdapter objAdapter = new ArrayAdapter<String>(AddStudentActivity.this,
                R.layout.layout_text_single_line_activated, getResources()
                        .getStringArray(R.array.arr_handicap_option));

    在微调器对象中设置适配器。

    spinner.setAdapter（objAdapter）;
