【问题描述】：
仍在努力解决这个问题，
丢失指向android:descendantFocusability="blocksDescendants" 的帖子是罪魁祸首，但我似乎仍然无法为我的ListView 获得onclick 事件。
我应该指出，当我点击列表时，背景会变成蓝色，好像点击已注册，只是代码中没有任何反应..
来自我的 main.class：

和我的主要活动

android:layout_alignParentTop="true"

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="@string/l_location"
android:id="@+id/textView"
android:layout_alignParentTop="true"
android:layout_toRightOf="@+id/imageView"
android:layout_alignEnd="@+id/textView2"
android:singleLine="false" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="@android:style/TextAppearance.DeviceDefault.Medium"
android:text="@string/l_mylocation"
android:id="@+id/textView2"
android:layout_below="@+id/textView"
android:layout_toRightOf="@+id/imageView"

<ListView
android:id="@id/android:list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/imageView" />
</RelativeLayout>
还有一些 GPS 信息在后台运行，每次位置更改时都会更新 textview2。
