Android 自定义BaseActivity

直接上代码：

BaseActivity代码：

tap_bar.xml(布局):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="64dp"android:layout_alignParentTop="true"android:background="@color/teal_700"android:id="@+id/topBarLL"android:orientation="horizontal"><!--顶部bar--><LinearLayoutandroid:id="@+id/tobBarContainer"android:layout_width="match_parent"android:layout_height="match_parent"android:visibility="visible"android:orientation="horizontal"><ImageViewandroid:id="@+id/topLeftImg"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center"android:layout_weight="5"android:src="@mipmap/ic_launcher"android:padding="10dp"/><TextViewandroid:id="@+id/topTitle"android:layout_width="match_parent"android:layout_height="match_parent"android:layout_weight="1"android:gravity="center"android:textStyle="bold"android:textSize="24sp"android:text="标题"android:textColor="@color/white"/><ImageViewandroid:id="@+id/topRightImg"android:layout_width="match_parent"android:layout_height="match_parent"android:gravity="center"android:layout_weight="5"android:src="@mipmap/ic_launcher"android:padding="10dp"/></LinearLayout></LinearLayout>

使用(MainActivity布局---继承BaseActivity)：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"><!--引入顶部标题栏--><includelayout="@layout/top_bar"/>**************</RelativeLayout>
