在下面的布局中，连接 textview 是从布局中出来的.

In the below layout connect textview was coming out of the layout.

device_item.xml:

device_item.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:orientation="horizontal"
    android:padding="10dp">


    <ImageView
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:padding="6dp"
        android:src="@drawable/lamp" />

    <TextView
        android:id="@+id/deviceName"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="left"
        android:textColor="@color/white"
        android:textSize="17sp"
        tools:text="Solar Enviro SSL 2016" />

    <TextView
        android:id="@+id/connect"
        android:layout_width="wrap_content"
        android:layout_height="22dp"
        android:background="@drawable/rounded_red_view"
        android:text="@string/connect"
        android:paddingBottom="1dp"
        android:paddingTop=".2dp"
        android:paddingLeft="15dp"
        android:paddingRight="15dp"
        android:textColor="@color/white"
        android:textSize="17sp" />
</LinearLayout>

推荐答案

使用线性布局代替 CoordinatorLayout.

Instead of CoordinatorLayout use linear layout.

如果你是初学者，开始使用线性布局编码.很容易理解.

if u r a beginner start coding with linear layout. It is easy to understand.

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
