Question

我将如何做到这一点。我能够使用getExtra传递一个xml字符串数组，但我不知道为包含一堆@drawable引用的整数数组执行它的语法。

继承人如何引用字符串数组

 //fills route detail image view with xml array of images
final TypedArray image =  getResources().obtainTypedArray(R.array.routeImage);

继承人我现在如何使用putExtra在我的mainactivity.java中使用字符串数组

routeListView.setOnItemClickListener(
        new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                String route = values[position];

                //for loop to increment through each route list item
                int i;
                for (i=0; i < values.length;i++)
                {
                    if (route.equals(values[i]))
                    {
                        Intent intent = new Intent(view.getContext(), RouteDetails.class);

和继承人 intent.putExtra（＆＃34; route＆＃34;，routeDetail [i]）; startActivity（意向）; } } } } ）;

并且在我的routeDetail.java中提到我的getExtra

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_route_details);

//TextView for route details
final TextView routeDetailsView = (TextView) findViewById(R.id.routeDetailsView);
routeDetailsView.setText(getIntent().getExtras().getString("route"));

//ImageView for route details
routeImage = (ImageView) findViewById(R.id.routeImage);
//routeImage.setImageResource(R.drawable.birdsboroareamap);

首先将图像资源存储在整数

中

intent.putExtra("imageResourceId", imageId);

然后在下面添加此代码，将路径Extra

routeImage.setImageResource(getIntent.getIntExtra("imageResourceId", 0);

然后得到Extra Like this

Sys.setenv(SPARK_HOME = "C:/Users/hms/Desktop/spark-2.0.1-bin-hadoop2.7/spark-2.0.1-bin-hadoop2.7",
           HADOOP_HOME = "C:/Users/hms/Desktop/spark-2.0.1-bin-hadoop2.7/spark-2.0.1-bin-hadoop2.7/tmp/hadoop")
.libPaths(c(file.path(Sys.getenv("SPARK_HOME"), "R", "lib"), .libPaths()))

library(SparkR)

sc<-sparkR.session( enableHiveSupport = FALSE, master="local[*]",
                    sparkHome=Sys.getenv("SPARK_HOME"),
                    sparkConfig = list(spark.driver.memory="2g",
                                       spark.driver.extraClassPath="C:/Users/hms/Desktop/spark-2.0.1-bin-hadoop2.7/spark-2.0.1-bin-hadoop2.7/jars/sqljdbc4.jar",
                                       spark.executor.extraClassPath="C:/Users/hms/Desktop/spark-2.0.1-bin-hadoop2.7/spark-2.0.1-bin-hadoop2.7/jars/sqljdbc4.jar",
                                       spark.sql.warehouse.dir="C:/Users/hms/Desktop/spark-2.0.1-bin-hadoop2.7/spark-2.0.1-bin-hadoop2.7/tmp/hadoop/bin") )



persons <- read.jdbc("jdbc:sqlserver://xpto//xpto:1433;databaseName=XPTO_XPTO", "table.XPTO", user = "XPTO", password = "XPTO")

使用getextra将xml整数数组与意图传递给另一个活动
