我按照本教程的步骤进行操作。我将我的项目命名为“HelloWorld3”而不是“HelloWorld”。我仔细地执行了所有步骤，并在我的“HelloWorldActivity.java”中删除了已经存在的内容（默认情况下），如下所示：
package com.esri.arcgis.android.samples.helloworld3;
import android.app.Activity;
import android.os.Bundle;
import com.esri.android.map.MapView;
public class HelloWorld3Activity extends Activity {
MapView mMapView ;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mMapView = new MapView(this);
}
@Override
protected void onDestroy() {
super.onDestroy();
}
@Override
protected void onPause() {
super.onPause();
mMapView.pause();
}
@Override protected void onResume() {
super.onResume();
mMapView.unpause();
}
}
我改变了以前的代码，并把这个代码改为：
public class HelloWorldActivity extends Activity {
MapView map = null;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Retrieve the map and initial extent from XML layout
map = (MapView)findViewById(R.id.map);
// Add dynamic layer to MapView
map.addLayer(new ArcGISTiledMapServiceLayer("" +
"http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"));
}
protected void onPause() {
super.onPause();
map.pause();
}
protected void onResume() {
super.onResume();
map.unpause();
}
}
（我遵循了教程中提到的内容，但我绝对将其命名为“HelloWorld3Activity”）
然后，我的代码变成了这样：
package com.esri.arcgis.android.samples.helloworld3;
import android.app.Activity;
import android.os.Bundle;
import com.esri.android.map.MapView;
public class HelloWorld3Activity extends Activity {
MapView map = null;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Retrieve the map and initial extent from XML layout
map = (MapView)findViewById(R.id.map);
// Add dynamic layer to MapView
map.addLayer(new ArcGISTiledMapServiceLayer("" +
"http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"));
}
protected void onPause() {
super.onPause();
map.pause();
}
protected void onResume() {
super.onResume();
map.unpause();
}
}
但是，“ArcGISTiledMapServiceLayer”下面有一个红色的下划线！！
问题是什么？！我不知道该怎么办！
我尝试通过单击 Ctrl+Shift+O >> 来更新丢失的导入来解决问题（希望它能解决问题。红色下划线消失了，我的代码变成了这样：
package com.esri.arcgis.android.samples.helloworld3;
import android.app.Activity;
import android.os.Bundle;
import com.esri.android.map.MapView;
import com.esri.android.map.ags.ArcGISTiledMapServiceLayer;
public class HelloWorld3Activity extends Activity {
MapView map = null;
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Retrieve the map and initial extent from XML layout
map = (MapView)findViewById(R.id.map);
// Add dynamic layer to MapView
map.addLayer(new ArcGISTiledMapServiceLayer("" +
"http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer"));
}
protected void onPause() {
super.onPause();
map.pause();
}
protected void onResume() {
super.onResume();
map.unpause();
}
}
之后，我尝试运行它。我右键单击我的项目“HelloWorld3”，然后单击 Run as > Android Application。模拟器启动了，我找到了我的应用程序的图标。但是，当我点击它时，出现了这个屏幕（或窗口）。
问题是什么？！请帮我！！

我不确定，但我认为这是 Logcat：
