如何使用屏幕限制调整textview?
how to adjust textview with screen limits?
我有一个 cardview,其中显示成分列表,但我面临的问题是有时成分名称变得太长,以至于它会将旁边的文本视图和按钮踢出屏幕。即使成分名称变长,如何在屏幕内调整整个卡片视图?
那是我的代码 ingredient_list.xml:
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="65dp"
app:cardCornerRadius="12dp"
app:cardElevation="5dp"
android:backgroundTint="#333333"
android:layout_margin="10dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#333333"
android:layout_margin="4dp"
android:padding="5dp"
android:orientation="horizontal">
<TextView
android:id="@+id/ith_ingredient_inventory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ingredient i"
android:gravity="center"
android:textColor="@color/colorAccent"
android:textSize="20dp"
android:textStyle="bold"
android:padding="10dp"

<TextView

<Button

我将您的 LinearLayout 更改为 ConstraintLayout 并进行了一些其他更改:
<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_margin="10dp"
android:backgroundTint="#333333"
app:cardCornerRadius="12dp"
app:cardElevation="5dp">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="4dp"
android:background="#333333"
android:padding="5dp">
<TextView
android:id="@+id/ith_ingredient_inventory"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:ellipsize="end"
android:gravity="center"
android:maxLines="1"
android:text="ingredient i ingredient i ingredient i ingredient i ingredient i"
android:textColor="@color/colorAccent"
android:textSize="20dp"
android:textStyle="bold"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="@+id/ith_ingredient_quantity_inventory"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/ith_ingredient_quantity_inventory"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:backgroundTint="@color/colorAccent"
android:text="100"
android:textAlignment="center"
android:textColor="@android:color/black"
android:textSize="20dp"
android:textStyle="bold"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toLeftOf="@+id/ith_ingredient_quantity_unit_inventory"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/ith_ingredient_quantity_unit_inventory"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="unit"
android:textColor="@color/colorAccent"
android:textSize="16dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toLeftOf="@+id/add_quantity_inventory"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="@+id/add_quantity_inventory"
android:layout_width="35dp"
android:layout_height="35dp"
android:layout_margin="10dp"
android:foreground="?attr/selectableItemBackgroundBorderless"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent"></Button>
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>
这是结果:
因此,您可以将 ConstraintLayout 与我的属性一起使用,而您希望不覆盖其他视图的 TextView 必须具有 maxLine 值和椭圆大小,以便在较长时在末尾显示三个点。
