android studio 自定义控件

第一种方式:

复制代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#ff28f010"
    android:layout_height="100px">


    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/ic_launcher"
        android:id="@+id/imageButton"
        android:gravity="center"
        android:text="返回"
        android:textColor="#f0a4cc"
        android:layout_margin="5dp"
        />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="100px"
        android:id="@+id/textView2"
        android:text="标题"
        android:gravity="center_vertical|center_horizontal"
        android:textSize="45px"

        android:layout_weight="0.23" />

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageButton2"
        android:layout_margin="5dp"
        android:background="@drawable/ic_launcher"
        android:textColor="#f0a4cc"
        android:text="编辑"/>


</LinearLayout>
复制代码

如果其他的地方引用,直接使用<include layout="@layout/title"/>
