最近要做一个项目，需要使用地图组件，于是准备使用第三方百度地图SDK来实现。

xml文件中

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <com.baidu.mapapi.map.MapView
        android:id="@+id/baiduMap"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:clickable="true"/>
</androidx.constraintlayout.widget.ConstraintLayout>

但是每次启动app时，总是闪退，报错如下

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: com.together.testmap10, PID: 32293
    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.together.testmap10/com.together.testmap10.MainActivity}: android.view.InflateException: Binary XML file line #8: Binary XML file line #8: Error inflating class com.baidu.mapapi.map.MapView

原因就是：

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //SDK初始化必须在setContentView前面执行
        SDKInitializer.initialize(getApplicationContext());
        setContentView(R.layout.activity_main);
    }

SDK初始化（SDKInitializer.initialize(getApplicationContext());）必须在setContentView前面执行
