LoginActivity.java

public class LoginActivity extends AppCompatActivity { 
        public static final String TAG = "ZCN_LoginActivity";
        private ImageView iv;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_login);
    
            ActionBar actionBar = getSupportActionBar();
            if (actionBar != null) {
                Log.d(TAG,"actionBar不为空");
                View titleView = LayoutInflater.from(this).inflate(R.layout.vrepair_actionbar, new LinearLayout(this), false);
                actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM); //Enable自定义的View
                actionBar.setCustomView(titleView);//设置自定义的布局
                iv = (ImageView)titleView.findViewById(R.id.iv_actionbar_back);
                iv.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        Log.d(TAG,"=====请输出=====");
                    }
                });
            }
        }
    }

vrepair\_actionbar.xml文件

<?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent">
        <ImageView android:id="@+id/iv_actionbar_back" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:background="@mipmap/ic_launcher"/>
        <TextView android:id="@+id/tv_actionbar_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:gravity="center" android:text="aaaaa" android:layout_centerInParent="true" />
    </RelativeLayout>

activity\_login.xml没什么特别的

<?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="match_parent" android:background="@color/white" tools:context="com.sdlj.vehiclerepair.activity.LoginActivity">
        <TextView android:layout_width="match_parent" android:layout_height="match_parent" android:text="我是主界面，哈哈哈哈" android:textColor="@color/black"/>
    
    </LinearLayout>
