我有一个白色背景的列表视图。我已将黑色设为文本颜色。问题是,如果你点击它就可以阅读列表视图中的文字,但只要你再次按住它就会再次显示为白色
这是xml:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#F7EFE8">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:text="SETTINGS"
android:textStyle="bold"
android:textColor="@android:color/black"
android:paddingTop="10dp"
android:paddingBottom="10dp"/>
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@android:color/black">
<TextView
android:id="@+id/selection"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@android:color/black"/>
<ListView
android:id="@+android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"
android:textColor="@android:color/black"/>
</LinearLayout>
</LinearLayout>
这是java:
public class SettingsActivity extends ListActivity {
TextView selection;
String[] items={"Change Password", "Save Credentials" };
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.settingsactivity);
setListAdapter(new `ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice,items));`
selection =(TextView)findViewById(R.id.selection);
}
public void onListItemClick(ListView parent, View v, int position, long id) {
selection.setText(items[position]);
}
}
