Question

当我使用MapBox库启动Android应用程序时，我得到了异常：

“android.view.InflateException：二进制XML文件行＃9：错误 inflating类com.mapbox.mapboxsdk.views.MapView“

字段“原因”包含以下文字：

java.lang.ClassNotFoundException：没找到类路径上的“com.mapbox.mapboxsdk.views.MapView”：DexPathList [[zip文件 “/data/app/com.example.my.mymapbox-2/base.apk"],nativeLibraryDirectories=[/data/app/com.example.my.mymapbox-2/lib/arm， / vendor / lib，/ system / lib]]

请帮助

这是我的代码：

的build.gradle

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.example.my.mymapbox"
    minSdkVersion 19
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:4.0.0-beta.2@aar'){
    transitive=true
}
}

MainActivity.java

package com.example.my.mymapbox;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

}

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:mapbox="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">

<com.mapbox.mapboxsdk.views.MapView
    android:id="@+id/mapview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    mapbox:access_token="@string/accessToken"/>
<!-- note the access token string created in the previous step -->
</RelativeLayout>

您的MapView XML必须为com.mapbox.mapboxsdk.maps.MapView而不是com.mapbox.mapboxsdk.views.MapView

使用最新的Mapbox Android SDK版本时可能会有所帮助：

compile ('com.mapbox.mapboxsdk:mapbox-android-sdk:4.0.0-rc.1@aar'){
    transitive=true
}

确保包含所有必需的权限以及遥测服务：

<service android:name="com.mapbox.mapboxsdk.telemetry.TelemetryService" />

要在4.0.0中控制MapView，有一个名为getMapAsync的新方法，它会在地图准备就绪时进行侦听。一旦它，您可以添加标记，更改相机位置等。所以您的onCreate看起来像这样：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mapView = (MapView) findViewById(R.id.mapview);
    mapView.onCreate(savedInstanceState);

    mapView.getMapAsync(new OnMapReadyCallback() {
        @Override
        public void onMapReady(MapboxMap mapboxMap) {

            // add markers, change camera position, etc. here!

        }

...

最后，请确保在活动生命周期中包含所有mapView方法。它看起来像这样：

// Activity lifecycle calls
@Override
protected void onStart() {
    super.onStart();
    mapView.onStart();
}

@Override
public void onResume() {
    super.onResume();
    mapView.onResume();
}

@Override
public void onPause() {
    super.onPause();
    mapView.onPause();
}

@Override
protected void onStop() {
    super.onStop();
    mapView.onStop();
}

@Override
protected void onDestroy() {
    super.onDestroy();
    mapView.onDestroy();
}

@Override
public void onLowMemory() {
    super.onLowMemory();
    mapView.onLowMemory();
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    mapView.onSaveInstanceState(outState);
}

希望这有帮助！

Answer 2

我也遇到了这个问题，但是当将此库添加到我的dependencies

时

implementation 'com.mapbox.mapboxsdk:mapbox-android-navigation-ui:0.23.0'

给予这些证据

Caused by: android.view.InflateException: Binary XML file line #0: Error inflating class com.mapbox.mapboxsdk.maps.MapView

即使我不使用导航！！然后我意识到我必须在setContentView

之前初始化Mapbox。

所以就这样移动

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //first initialize Mapbox
    Mapbox.getInstance(this, YOUR_MAPBOX_KEY);
    //then 
    setContentView(R.layout.activity_main);
}

我的问题解决了

Android MapBox充气错误。没找到类MapView
