問題描述

SDK 18 有問題.我的文本視圖的重力不能垂直工作.但它適用于 sdk17.

I have a probleme with the SDK 18. The gravity of my text view doesn't work vertically. But it's working with sdk17.

圖片和代碼:

header_of_listView.xml:

header_of_listView.xml :

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/RelativeLayout1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="horizontal" >

        <ImageView
            android:id="@+id/iv_bg"
            android:layout_width="wrap_content"
            android:layout_height="@dimen/entete.size.h"
            android:layout_alignParentLeft="true"
            android:layout_alignParentRight="true"
            android:layout_centerHorizontal="true"
            android:contentDescription="@string/blank"
            android:scaleType="fitXY"
            android:src="@drawable/cellule_flecher_mise_en_valeur" />

        <TextView
            android:id="@+id/tv_message"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@id/iv_bg"
            android:layout_alignLeft="@id/iv_bg"
            android:layout_alignRight="@id/iv_bg"
            android:layout_alignTop="@id/iv_bg"
            android:layout_marginBottom="6dp"
            android:gravity="center"
            android:text="@string/a_remplacer"
            android:textColor="@color/tableviewText"
            android:textSize="18sp"
            android:textStyle="bold" 
            android:layout_centerHorizontal="true"/>

    </RelativeLayout>

AndroidManifest.xml

AndroidManifest.xml

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

AndroidManifest.xml

AndroidManifest.xml

<uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

textview 為黑色背景android:background="#000000"

with black background for textview android:background="#000000"

如果有人有想法.我嘗試用 match_parent 更改 wrap_content.

If someone have an idea. I have try to change wrap_content with match_parent.

唯一有效的是android:layout_height="@dimen/entete.size.h" 在 TextView 上，但邊距不適用.目前我將項目留給 SDK 17.

The only thing that work is android:layout_height="@dimen/entete.size.h" on the TextView, but the margin doesn't apply. For the moment I leave the project to SDK 17.

推薦答案

問題是 RelativLayout 作為 listview 項的根布局.如果您在 RelativeLayout 周圍放置一個 LinearLayout，它也適用于 targetSdk = 19.GridView 也會出現同樣的問題.

The problem is the RelativLayout as root layout of the listview item. If your put a LinearLayout around the RelativeLayout it works also with targetSdk = 19. Same problem appears with the GridView.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent">

   ... your layout like before

</LinearLayout>

這不是一個很好的解決方法 - 但我猜比將 targetSdk = 17 更好.

This is not really a nice workaround - but better than put targetSdk = 17 I guess.
