如果我使用 .75 和 .25,为什么布局权重不起作用?
Why is layout weight not working if I use .75 and .25?
这是我的 XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceSmall"
android:text="8 diciembre, 2015"
android:id="@+id/txtFecha"
android:textAlignment="textEnd"
android:layout_margin="5dp"
android:layout_gravity="right" />
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="1"
android:layout_margin="10dp">
<TextView
android:layout_width="0dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text"
android:id="@+id/txtTituloNot"
android:layout_height="wrap_content"
android:maxHeight="52dp"
android:layout_weight="1" />
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:src="@drawable/feclaabajo"
android:layout_below="@+id/txtTituloNot"
android:scaleType="fitXY"
android:adjustViewBounds="false"
android:layout_weight="1" />
</LinearLayout>
<TextView
android:layout_width="fill_parent"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Medium Text Medium Text Medium Text Medium Text
Medium Text Medium Text Medium Text Medium Text Medium Text
Medium Text Medium Text Medium Text Medium Text Medium Text
Medium Text Medium Text Medium Text Medium Text Medium Text Medium"
android:id="@+id/txtExtracto"
android:layout_margin="5dp"
android:maxHeight="110dp"
android:layout_height="wrap_content" />
<ImageView
android:layout_width="233dp"
android:layout_height="170dp"
android:id="@+id/imageViewNoticia"
android:src="@drawable/imagenodisponible"
android:soundEffectsEnabled="false"
android:layout_gravity="center_horizontal"
android:scaleType="fitXY"
android:layout_marginBottom="7dp" />
</LinearLayout>
但现在我只使用以下代码:
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="1"
android:layout_margin="10dp">
<TextView
android:layout_width="0dp"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text Large Text"
android:id="@+id/txtTituloNot"
android:layout_height="wrap_content"
android:maxHeight="52dp"
android:layout_weight="1" />
<ImageView
android:layout_width="0dp"
android:layout_height="wrap_content"
android:id="@+id/imageView"
android:src="@drawable/feclaabajo"
android:layout_below="@+id/txtTituloNot"
android:scaleType="fitXY"
android:adjustViewBounds="false"
android:layout_weight="1" />
</LinearLayout>
如您所见,imageview 和 textview 具有:
android:layout_weight="1"
但这就是它:
图片浏览没看到,Textview
有100%
我设置的任何值Imageview
这不会改变
现在,如果我将文本的值更改为 0 到 .99 之间的值
(图像视图但重量为 1):
如果我使用 .75 和 .25 效果很好,但如果我设置 3 和 1 则效果不佳
我希望能够使用最后一个
