Question

我正在使用下面的代码，但它不起作用。为什么？

MainActivity：

final SongAdapter songAdt = new SongAdapter(getApplicationContext(), songList);
lv.setAdapter(songAdt);

lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
      @Override
      public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

           view.setSelected(true);
           ...

的ListView：

<ListView android:id="@+id/lvP" android:layout_width="fill_parent"
    android:scrollbars="vertical"
    android:fadeScrollbars="false"
    android:layout_height="0dp" android:layout_weight="0.57"android:divider="#555555"
    android:drawSelectorOnTop="true"
    android:background="@drawable/bg_key" />

bg_key.xml：

<?xml version="1.0" encoding="utf-8"?>
<selector
    android:id="@+id/myselector"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Non focused states -->
    <item
        android:state_focused="false"
        android:drawable="@color/activated_color" />
    <item
        android:state_activated="false"
        android:drawable="@color/activated_color" />
    <item
        android:state_selected="true"
        android:drawable="@color/activated_color" />
    <item
        android:drawable="@color/default_color" />
</selector>

color.xml：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="pressed_color">#222222</color>
    <color name="activated_color">#1d1d1d</color>
    <color name="checked_color">#ff0000</color>
    <color name="default_color">#111111</color>
</resources>

编辑：

根据建议，我删除了android：background =＆＃34; @ drawable / bg_key＆＃34;从ListView然后我添加到

song_layout.xml：

<?xml version="1.0" encoding="utf-8"?>

Answer 1

将您的选择器属性更改为此选项，并使用编辑后的Que android:state_focused="true" android:state_activated="true" android:state_selected="true"中的背景。

Answer 2

在列表项目上使用此单击：

    View rowView = view;
setItemSelected(rowView); //use this inside on item click

 public void setItemSelected(View view){
    View rowView = view;
    TextView tv = (TextView)rowView.findViewById(R.id.textView_two); // try your text view here
    tv.setTextColor(Color.WHITE);
}
