我使用下面的选择来改变文字的外观在ListView项目：

I am using the following selector to change the appearance of text in a listView item:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
          android:color="#FFFFFFFF" /> <!-- checked -->
    <item android:state_activated="true"
          android:color="#FFFFFFFF" /> <!-- activated -->
    <item android:state_pressed="true"
          android:color="#FFFFFFFF" /> <!-- pressed -->
    <item android:state_focused="true"
          android:color="#FFFFFFFF" /> <!-- focused -->
    <item android:color="#FF000000" /> <!-- default -->
</selector>

整个选择器工作正常，在更高版本Android的（ICS，JB），但姜饼，而pressed_state项目正在正确应用，当我打电话setItemChecked在列表视图中，state_checked项目不适用。

The entire selector works fine on later versions of Android (ICS, JB), but on Gingerbread, while the pressed_state item is being applied correctly, when I call setItemChecked on the listView, the state_checked item isn't applied.

在code我使用设定的项目如下：

The code I am using to set the item is as follows:

@Override
protected void onResume()
{
    super.onResume();

    getListView().setChoiceMode(ListView.CHOICE_MODE_SINGLE);
    for (int index = 0; index < measureList.size(); index++)
    {
        if (measureList.get(index).getId() == appContext.getMeasureId())
        {
            getListView().setItemChecked(index, true);
        }
    }
}

和用于设置选择的XML是这样的：

and the xml used to set the selector is this:

<TextView
        android:id="@+id/item_text"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent"
        android:layout_marginTop="8dp"
        android:layout_marginLeft="8dp"
        android:paddingRight="10dp"
        android:ellipsize="end"
        android:layout_toRightOf="@id/item_thumb"
        android:maxLines="1"
        android:scrollHorizontally="true"
        android:textStyle="bold"
        android:textSize="16sp"
        android:textColor="@color/selected_text_selector"
        />

有谁知道为什么会这样？我还没有测试它在Android GB和ICS之间的版本，但只要我做编辑这篇文章。

Does anyone know why this happens? I haven't yet tested it out on versions of Android between GB and ICS, but will edit this post as soon as I do.

推荐答案

一点点搜索后，在我看来，其原因是， state_checked 不前pressed pre-蜂窝是一个事实，即在查看的 SETACTIVE 方法不可用API级别11日前这意味着选中状态不会传播到我的布局的子视图。

After a little searching, it seems to me the reason that the state_checked isn't expressed pre-Honeycomb is the fact that the setActive method on View is not available before API level 11. This means that the checked state is not propagated to the child views of my layout.

的关键是：

1）中的在XML一个简单的开关，以及用于2）我修改$ C $中的c通过沃伊库链接到答案，得到下列：

1) Was a simple switch in the XML, and for 2) I modified the code in the answer linked to by Voicu to give the following:

public class CheckableRelativeLayout extends RelativeLayout implements Checkable
{
    private boolean checked = false;

    public CheckableRelativeLayout(Context context) {
        super(context, null);
    }

    public CheckableRelativeLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    private static final int[] CheckedStateSet = {
            R.attr.state_checked
    };

    @Override
    protected void dispatchSetPressed(boolean pressed)
    {
        super.dispatchSetPressed(pressed);
        setChecked(pressed);
    }

    @Override
    public void setChecked(boolean checked) {
        this.checked = checked;
        for (int index = 0; index < getChildCount(); index++)
        {
            View view = getChildAt(index);
            if (view.getClass().toString().equals(CheckedTextView.class.toString()))
            {
                CheckedTextView checkable = (CheckedTextView)view;
                checkable.setChecked(checked);
                checkable.refreshDrawableState();
            }
        }
        refreshDrawableState();
    }

    public boolean isChecked() {
        return checked;
    }

    public void toggle() {
        checked = !checked;
        refreshDrawableState();
    }

    @Override
    protected int[] onCreateDrawableState(int extraSpace) {
        final int[] drawableState = super.onCreateDrawableState(extraSpace + 1);
        if (isChecked()) {
            mergeDrawableStates(drawableState, CheckedStateSet);
        }
        return drawableState;
    }

    @Override
    public boolean performClick() {
        return super.performClick();
    }
}
