Question

这里的问题是我试图使用“alignParentBottom = true”将textview粘贴到底部，但它隐藏了textview。以下是布局xml文件：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">

<Switch
    android:onClick="adjustFocus"
    android:layout_margin="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/hhmm"
    android:id="@+id/hhmm"
    android:checked="false"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

<Switch
    android:onClick="adjustFocus"
    android:layout_margin="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/hr12"
    android:id="@+id/hr12"
    android:checked="false"
    android:layout_below="@+id/hhmm" />

<Switch
    android:onClick="adjustFocus"
    android:layout_margin="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/hr24"
    android:id="@+id/hr24"
    android:checked="false"
    android:layout_below="@+id/hr12" />
<Switch
    android:onClick="adjustFocus"
    android:layout_margin="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/hh_double"
    android:id="@+id/hhdbl"
    android:checked="false"
    android:layout_below="@+id/hr24" />
<Switch
    android:onClick="adjustFocus"
    android:layout_margin="10dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/mm_double"
    android:id="@+id/mmdbl"
    android:checked="false"
    android:layout_below="@+id/hhdbl" />



<TextView
    android:textColor="@color/black"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceSmall"
    android:text="@string/offset"
    android:id="@+id/textView2"
    android:layout_below="@+id/mmdbl"
    android:layout_margin="10dp" />


 //below is the textview I'm trying to stick to the bottom
    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Large Text"
        android:id="@+id/textView3"
        android:background="@color/black"
        android:textColor="@color/white"
        android:layout_alignParentBottom="true"
/>
</RelativeLayout>

以下是与上述布局xml文件关联的java代码。这是一个片段......

public class myfrag extends Fragment {
TextView tv;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.my_fragment, container, false);
tv = (TextView)v.findViewById(R.id.textView3);


return v;
}

}

请在我错的地方帮助我。

更新此TextView：

 <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Large Text"
        android:id="@+id/textView3"
        android:background="#111111"
        android:textColor="@color/white"
        android:layout_alignParentBottom="true"
        android:layout_below="@+id/textView2"
        android:gravity="center|bottom" />

alignParentBottom隐藏了textview
