startActivity工具類

提取startActivity方法為自己的工具類，代碼如下：

public static void launchActivity(Context context, Class<?> activity,Map<String, Object> extraMap) {

Intent intent = new Intent(context, activity);

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

if(extraMap != null){

Iterator<String> iterator = extraMap.keySet().iterator();

while(iterator.hasNext()){

String key = (String) iterator.next();

Object object = extraMap.get(key);

if (object instanceof String) {

intent.putExtra(key, (String)object);

} else if (object instanceof Boolean) {

intent.putExtra(key, (Boolean) object);

} else if (object instanceof Float) {

intent.putExtra(key, Float.parseFloat(object.toString()));

} else if (object instanceof Integer) {

intent.putExtra(key, Integer.parseInt(object.toString()));

} else if (object instanceof Long) {

intent.putExtra(key, Long.parseLong(object.toString()));

} else {

intent.putExtra(key, object.toString());

}

}

}

context.startActivity(intent);

}
