我想使用API GoogleMaps为国家/地区着色。该代码有效,但我使用的是搜索栏,用户可以在其中输入其他国家/地区名称。
private void colorCountry(String searchString){
String myVar = searchString + "_geojson";
Toast.makeText(this, searchString , Toast.LENGTH_SHORT).show();
try {
GeoJsonLayer layer = new GeoJsonLayer(nMap, R.raw.france_geojson, getApplicationContext());
GeoJsonPolygonStyle style = layer.getDefaultPolygonStyle();
style.setFillColor(Color.BLUE);
style.setStrokeColor(Color.BLUE);
style.setStrokeWidth(1F);
layer.addLayerToMap();
} catch (IOException ex) {
Log.e("IOException", ex.getLocalizedMessage());
} catch (JSONException ex) {
Log.e("JSONException", ex.getLocalizedMessage());
}
}
如何在GeoJsonLayer中用变量“ myVar”替换“ france_geojson”?
GeoJsonLayer layer = new GeoJsonLayer(nMap, R.raw.france_geojson, getApplicationContext());
答案 0 :(得分:0)
使用此:
int rawId = getApplicationContext()
.getResources()
.getIdentifier(myVar, "raw", getApplicationContext().getPackageName());
获取myVar
的ID,然后:
GeoJsonLayer layer = new GeoJsonLayer(nMap, rawId, getApplicationContext());
