android - TextView 在 RelativeLayout 中离开屏幕

Question

这是布局:

<?xml version="1.0" encoding="utf-8"?>

<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:columnCount="2"
    android:rowCount="2"
    android:rowOrderPreserved="true"
    android:alignmentMode="alignMargins">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_row="0"
        android:layout_column="0"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Test:" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_row="0"
        android:layout_column="1"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="too long line too long line too long line too long line" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Test2:"
        android:paddingRight="10dp"
        android:layout_row="1"
        android:layout_column="0" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_row="1"
        android:layout_column="1"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Test line" />
</GridLayout>

如何防止第二个 TextView(屏幕截图中选择的那个)越过屏幕边界？

Answer 1

您可以通过为每个 TextView 提供 match_parent 宽度和适当的 layout_weight 来避免所有这些情况。下面的代码将为您提供您所需要的。享受吧!

<?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" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="3"
            android:text="Test 1"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="line too long line too long line too long line too long line too long "/>
        </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="3"
            android:text="Test 2"/>

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="line too long line too long line too long line too long line too long "/>
    </LinearLayout>

</LinearLayout>
