在RelativeLayout中使用重力对齐TextView(Right align TextView using gravity in RelativeLayout)

在RelativeLayout中使用重力对齐TextView(Right align TextView using gravity in RelativeLayout)

我试图让editText坐在我的布局的右边缘，左边有一个按钮，如下所示：

<RelativeLayout android:id="@+id/FindClientLayout" android:layout_width="@dimen/third_width" android:layout_height="@dimen/half_height" android:layout_alignParentLeft="false" android:layout_alignParentRight="true" android:layout_alignParentTop="false" android:layout_below="@id/HeaderLayout" android:layout_margin="@dimen/fragment_separation" android:layout_toRightOf="@id/scrollViewRecommend" android:background="@drawable/login_border" > <TextView android:id="@+id/textViewFindClient" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/find_client" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="@color/Black" /> <EditText android:id="@+id/editTextClient" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:gravity="center_vertical|right" android:inputType="text"/> <Spinner android:id="@+id/spinnerClientList" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:layout_below="@id/editTextClient"/> <Button android:id="@+id/buttonDoFind" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_toLeftOf="@id/editTextClient" android:text="@string/find" /> </RelativeLayout>

该按钮不可见，结果如下所示：

我假设按钮是不可见的，因为editText是左对齐的，并覆盖它或将它从布局框架中推出。 为什么editText和spinner左对齐而不是右对齐？ 另外，为什么editText不是垂直居中？

I am trying to get an editText to sit on the right edge of my layout, with a button to its left, as follows:

<RelativeLayout android:id="@+id/FindClientLayout" android:layout_width="@dimen/third_width" android:layout_height="@dimen/half_height" android:layout_alignParentLeft="false" android:layout_alignParentRight="true" android:layout_alignParentTop="false" android:layout_below="@id/HeaderLayout" android:layout_margin="@dimen/fragment_separation" android:layout_toRightOf="@id/scrollViewRecommend" android:background="@drawable/login_border" > <TextView android:id="@+id/textViewFindClient" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/find_client" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="@color/Black" /> <EditText android:id="@+id/editTextClient" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:gravity="center_vertical|right" android:inputType="text"/> <Spinner android:id="@+id/spinnerClientList" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:layout_below="@id/editTextClient"/> <Button android:id="@+id/buttonDoFind" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_toLeftOf="@id/editTextClient" android:text="@string/find" /> </RelativeLayout>

The button is invisible, and the result looks like this:

I assume the button is invisible because the editText is left-aligned and overlays it or pushes it out of the layout frame. Why is are the editText and spinner left aligned rather than right-aligned? Also, why is the editText not centered vertically?

最满意答案

像这样编辑你的xml文件并检查结果

<TextView android:id="@+id/textViewFindClient" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/find_client" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="@color/Black" /> <EditText android:id="@+id/editTextClient" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:inputType="text"/> <Spinner android:id="@+id/spinnerClientList" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:layout_below="@id/editTextClient"/> <Button android:id="@+id/buttonDoFind" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_toLeftOf="@id/editTextClient" android:text="@string/find" />

这应该解决您的问题，即您正在使用重力将edittext置于右侧，但重力实际上用于定位视图的内容而不是视图本身。

如果你仍然面临问题留下评论

Edit you xml file like this and check for result

<TextView android:id="@+id/textViewFindClient" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:text="@string/find_client" android:textAppearance="?android:attr/textAppearanceLarge" android:textColor="@color/Black" /> <EditText android:id="@+id/editTextClient" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:inputType="text"/> <Spinner android:id="@+id/spinnerClientList" android:layout_width="@dimen/input_text_width" android:layout_height="wrap_content" android:layout_below="@id/editTextClient"/> <Button android:id="@+id/buttonDoFind" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center_vertical" android:layout_toLeftOf="@id/editTextClient" android:text="@string/find" />

this should solve your problem which is , you are using gravity to place the edittext on right but gravity is actually use to position the content of view not the view itself.
