对齐ImageView& LinearLayout中的TextView [英] Align ImageView & TextView inside LinearLayout

问题描述

我有一个LinearLayout，里面有一个ImageView和TextView。我想将LinearLayout的中心与ImageView下方的Im​​ageView和TextView对齐。

I have a LinearLayout and inside, a ImageView and TextView. I want to align the center of the LinearLayout the ImageView and the TextView below the ImageView.

我只在LinearLayout中获得顶部对齐ImageView。我该怎么做？

I only get the top align ImageView in LinearLayout. How I can do?

       <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="center_horizontal"
            android:layout_weight="1"
            android:layout_margin="8dp"
            android:gravity="center_horizontal"
            android:orientation="vertical" >

            <ImageView
                android:id="@+id/boton"
                android:layout_width="90dp"
                android:layout_height="90dp"
                android:layout_gravity="center"
                android:background="@drawable/plano"
                android:gravity="center" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Plano"
                android:textSize="23sp"
                android:textStyle="bold"
                />

        </LinearLayout>

推荐答案

我会告诉你如何做同样的服用RelativeLayout和TextView的复合可绘制的优点：

I'll show you how to do the same taking advantage of a RelativeLayout and a TextView's compoundDrawable:

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center_horizontal"
    android:layout_margin="8dp"
    >
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:drawableTop="@drawable/plano"
        android:drawablePadding="8dp"
        android:text="Plano"
        android:textSize="23sp"
        android:textStyle="bold"
    />
</RelativeLayout>

复合绘图有助于保持视图计数，因此本质上加快了布局

Compound drawables help keeping down the View count, and therefore intrinsically speed up the layout

关键是 android：drawableTop =@ drawable / plano这取代了顶部的图像。

你也可以设置右侧，左侧，下侧图像。

甚至全部一起。

The key is android:drawableTop="@drawable/plano" This replaces the top image.
You can also set a Right, Left, Bottom side image.
Even all together.
