我想像这张图片一样创建一个简单的卡片布局

这是我的布局

                <TextView
                    android:text="this is a simple discription with losts of text sjdun a;daiwn adwi"
                    android:layout_width="match_parent"

                <TextView
                    android:text="Distance"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:id="@+id/txt_distance"
                    android:textAlignment="textEnd"
                    android:drawableRight="@drawable/ic_settings_black_24dp"
                    android:hapticFeedbackEnabled="false"
                    android:layoutDirection="rtl" />

            </LinearLayout>

        </LinearLayout>
    </android.support.v7.widget.CardView>
</LinearLayout>

这是结果

你可以看到左图像高度依赖于右边的文本。如何改变这种布局并使其稳定，因为通过改变文本图像将会移动，我还添加了一张根本没有出现的图像（img_logo）。请你帮我找一个好的解决方案改革我的布局？感谢

为了保持您的情况下的布局比例，您可以在TextView上使用此XML属性android:ellipsize和android:maxLines。

TextView示例：

<TextView android:id="@+id/txt_discription"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColor="#FFFFFF"
    android:ellipsize="end"
    android:maxLines="2"
    tools:text="This is a simple discription with losts of text lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."
    />

这是使用以前的TextView将CardView转换为XML布局文件的简单示例：

<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/card_view"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:layout_margin="8dp"
    card_view:cardCornerRadius="4dp"
    >

    <ImageView
        android:id="@+id/card_background_image"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:scaleType="centerCrop"
        tools:src="@android:mipmap/sym_def_app_icon"
        />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" 
        android:background="@android:drawable/screen_background_dark_transparent"
        android:layout_gravity="bottom"
        android:padding="16dp"
        >
        <TextView
            android:id="@+id/card_title"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingTop="8dp"
            android:paddingBottom="8dp"
            android:textAllCaps="true"
            android:textStyle="bold"
            android:textColor="#FFFFFF"
            android:ellipsize="end"
            android:maxLines="1"
            tools:text="Cart title"
            />

        <TextView android:id="@+id/txt_discription"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textColor="#FFFFFF"
            android:ellipsize="end"
            android:maxLines="2"
            tools:text="this is a simple discription with losts of text lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua."
            />

    </LinearLayout>
</android.support.v7.widget.CardView>

希望它有所帮助。
